Every single game has "stopped working" since installing GTX 660


Recommended Posts

Did a google search for this and a lot of talk was floating around about messages concerning driver crashes but I haven't been getting that. I just swapped out my GTX 260 for a GTX 660, uninstalled all drivers, installed the GPU, installed the latest nvidia drivers and every game I go into crashes and I get a message saying "Far Cry 3 has stopped working". (Or whatever game I may try.) I have a 500W Antec Earthwatts PSU, minimum requirement is 450W. I'm also running a Q6600 OC'd to 3.4Ghz on a Gigabyte motherboard with PCI E 2.0. I've tried a couple driver reinstalls and reboots but no such luck. I'm trying a reinstall of DX now just in case.

EVGA GTX 660 SC

Q6600 @ 3.4 GHz

Antec Earthwatts 500W PSU

I should also note it seems to always happen right after the intial logo screen for the game or a developer logo screen, never during any gameplay. I've also run the EVGA stress test on the GPU with no crashes or issues. Could it be my OC?

You might try Driver Sweeper and see if that helps, but I'm betting the main power rails aren't giving enough juice.

Antec Earthwatts 500W PSU lists this: +3.3V@25A, +5V@24A, +12V1@22A, +12V2@22A, [email protected], [email protected] (Newegg)

EVGA GTX 660 SC needs this: Minimum of a 450 Watt power supply. Minimum recommended power supply with +12 Volt current rating of 24 Amps. (EVGA)

So it seems, both your +12V rails are 2 amps too low, and I'm guess as power hungry as nVidia cards are, that's the problem.

Grab another PSU (keep your receipt) and see if that solves the problem, if so card is good need to keep the PSU. If no change card is probably bad.

DavidM is right. It's your power supply. When you launch a game, a video card draws more power. In your case, not enough electricity is being moved from your PSU to your video card because of the lower amperage (22A vs. the required 24A).

If the GTX 260 worked fine it needed Minimum of a 500 Watt power supply

(Minimum recommended power supply with +12 Volt current rating of 36 amps).

So before you get a new PSU which wouldn?t be a bad thing reset your CPU to stock reinstall the OS if needed and try that.

Could you have bumped something in there? Or maybe even ... some bad VRAM so when games load, hits a certain point in the RAM and *boom*? Probably not... I think Peter has the right of it, start by resetting everything.

1. Is your BIOS up to date? If not do so now.

2. Clear your bios with cmos jumper. Set everything back up, but don't overclock for the time being.

3. Try your games again. If they crash, try running Furmark. Does it crash on you? Does anything seem out of the ordinary?

4. If Furmark crashes, Try to get a better power supply. You are stressing it with that setup.

5. Still crashing? RMA the card.

Edit: Can't hurt to do a memtest too.

Thanks for the replies! I went ahead and just decreased my OC. Well, took it back to stock and everything works fine. I guess I figured if it worked fine with my OC before it would now but perhaps the increased voltage combined with the different PSU requirements caused the issue? Either way, I'm happy. I mainly kept the OC at 3.4 - 3.6 to help prevent bottlenecking but honestly, if there is a bottleneck I sure didn't notice it. This thing flies! Still tempted to take advantage of the step up program in the next 90 days and get the 660Ti...

I will be investing in a new PSU though I think since I plan on getting a new CPU, motherboard and ram in the next couple of months.

Awesome! Glad it worked for you! :)

Yeah definitely get something with a little more headroom. Probably at least a 750W. By running it at it's threshold, you're probably lowering it's lifespan, so you'd hate to have it die and then be out of commission while you wait for a new one to ship.

If the PSU has plenty of overhead, you should get a nice long life out of it. And it'll be a lot more future-proof too for future builds. :)

Might have spoken too soon. After playing some Far Cry 3 and exiting to the desktop, the game froze on a loading screen. Then a few minutes after running a stress test in Furmark everything stopped responding in Windows and I had to force restart. Looks like I should be checking out a new PSU...

It's most likely a faulty card. Update your board's BIOS. I've had it like this except that system would crash turning on Aero.

If no joy, test the card in another computer to be sure and that's it.

As for PSU, it might be going south and is of suboptimal brand as it is, but even then it's not marginal at all, having run GTX 260 without a hitch. Which is a big giveaway, actually. While higher wattage PSUs tend to be several percent more efficient, people are obsessed with their kilowatt PSUs as if it's horsepower of a car or something.

Also, I wish I could downvote people talking out of their ass about amps. Driving 22 amps through a single 6-pin PEG GTX 660 has (given that small part of the required power comes through the other +12V rail routed through the slot itself), with 18 gauge wires packed so close together would not only crash the game, but burn your house down.

Power supplies also do gradually lose capability over time. You didn't mention how old your power supply is, but no matter what, it seems to be the most marginal, so replacing the power supply should solve your woes.

They either work, or they don't.. so they are either good or faulty. There is no "gradually lose capability over time" with hardware...

Not actually true. Leaky capacitors can be a bitch.

Aww...well that's a crock. :( What PSU are you going to get? Do you have another machine you can at least test and benchmark the card in?

Everything degrades in time and with use. So do electrolytic caps. Especially bad quality ones.

And while we're on the subject, so does magnetic field of hard disk platters, charge in flash drives decreases, if unused, and, in fact, semiconductors do degrade, albeit very slowly.

Caps do fail gradually, inhibiting their performance. Rest of things mentioned work until they fail.

They either work, or they don't.. so they are either good or faulty. There is no "gradually lose capability over time" with hardware...

Here's a footnote from a power supply calculator site.

Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years.

Well silly me, I forgot to change my voltage on my CPU back down to stock after decreasing my OC. Running at stock speeds with stock voltage and everything is fine. I'll gradually overclock my PC and test for issues but for now all is well. I had it stable at 3.2 with stock voltage before the GPU upgrade so I'll try that again and see. Maybe it was just my voltage all along. I guess I should pay more attention :p.

haha, Alright. Tell us if you run into anything else. Glad it's working for you. :)

Sorry about that - I was logged in to an out of use FB account on my phone and didn't realize it. Plus, I wasn't able to upload those images.post-45347-0-70704000-1358235982.gifpost-45347-0-45737700-1358236013.gif

I guess the whole reason I was thinking PSU (and forgive my ignorance) is things just started crashing..For example, I opened Chrome and it just ran sluggish and unresponsive. Even trying to pull up the task manager to end the task was delayed and after the system "caught up", I had to restart to have any type of performance I could use. I just didn't think a GPU could cause those issues. Again, my own ignorance.

    • All these CEOs got the biggest boners thinking about firing employees for AI. Turned out it was just a wet dream.
    • And the fact that the majority of people from Poland are white European Christians while the people you are complaining about in post after post are not is just a coincidence... Every sentence in your post I am replying to is racist nonsense. None of it is actually based on any facts whatsoever. All immigrants are seeking a better life too. It's literally the only reason they would risk everything and leave their homes, families, and homeland. They are working and contributing to the economy too, as you even admit. They get the same benefits your partner did AND that YOU are eligible for as well. That is one of the key things of the EU and a mark of a civilization. That is the definition of a society where everyone is given a chance, treated equally and fairly, and is judged by the content of their character, not their different skin color or which version of ignorant superstitious nonsense their parents lied about as children. Racists around the world said the same things about the Irish and Jews and Poles (like your partner) and...every other immigrant movement over the centuries. What's your family's heritage, by the way? Were your ancestors lied about with racist fearmongering crapola by self-entitled locals the same way as you are now? If someone like that said the same things about all people from Poland, like your partner, would they be right? Or would you want them to judge your partner based on who they actually were, not where they just happened to come from?
    • Again, this is an irrelevant attempt to attack the messenger. The truth does not require any justification.

    • Why it's almost impossible to produce a smartphone in the United States by Hamid Ganji If you look at the back of some Apple products, you can see the famous phrase “Designed by Apple in California, Assembled in China.” This phrase appears on products from one of the largest smartphone brands in the United States. These products are designed in the U.S., but their manufacturing takes place in China, India, Vietnam, or even Brazil. But why can’t Apple, as one of the largest American tech companies, produce its iPhones on U.S. soil? The idea for this topic came to me after the Trump Foundation launched a smartphone called the T1 and claimed that it was designed and built with American values in mind. However, this claim did not last long, as it was revealed that Trump’s phone was actually a rebranded HTC U24 Pro, with only a gold case and minor internal component changes. You see? Even a phone that is supposed to represent American values is manufactured in China. With a gross domestic product (GDP) exceeding $32 trillion, the United States is currently the world’s largest economy, while China ranks second with around $20 trillion. On the other hand, the United States is by a wide margin the global leader in various technological fields, and American companies spend hundreds of billions of dollars annually on research and development. From Apple and Google to Microsoft, Lockheed Martin, Boeing, and others, American tech and industrial giants lead their foreign competitors in many sectors. The United States also has no shortage of smartphone brands. Apple, Google, and Motorola are among the major brands in the smartphone market, collectively holding a significant share. However, the vast majority of their products are manufactured outside the United States. So why is it that the world’s largest economy, home to the most advanced technology companies and industrial powers, cannot produce a smartphone on its own soil? Let’s explore this question together. Even threats to impose tariffs won’t work After Trump entered the White House as the 47th President of the United States, his administration adopted strict tariff policies. One of these policies was the imposition of a 25% tariff on smartphones manufactured outside the United States. Trump said he “had a little problem” with Apple CEO Tim Cook over producing smartphones outside the U.S. So he thought that threatening a 25% tax on imported phones might force Apple to bring manufacturing back to the United States. “I have long ago informed Tim Cook of Apple that I expect their iPhones that will be sold in the United States of America will be manufactured and built in the United States, not India, or anyplace else,” Trump wrote on Truth Social. Image via The White House Although Apple currently manufactures some of the iPhone’s chips in the United States with TSMC's help, it still shows no willingness to shift full iPhone production to the country. At the time, renowned Apple supply chain analyst Ming-Chi Kuo wrote on X, “In terms of profitability, it’s way better for Apple to take the hit of a 25% tariff on iPhones sold in the US market than to move iPhone assembly lines back to the US.” However, manufacturing a smartphone in the United States is not as easy as it might seem, and many technical and economic barriers are involved. The lack of necessary manufacturing hubs There is a clear reason why many companies prefer to manufacture their products in China. China has established itself as the main global manufacturing hub for international companies, and over the past few decades, large contract manufacturers have emerged there, allowing companies like Apple to outsource production. One such example is Foxconn, which also manufactures some Apple products in India. Building the infrastructure required to produce smartphones in the United States would require tens of billions of dollars in new investment. Factories would need to be built, essential manufacturing equipment would have to be installed, and, most importantly, a skilled workforce capable of operating these systems would need to be recruited and trained. The United States currently lacks the core infrastructure needed to manufacture smartphones, and for this reason, many companies prefer to outsource production to Chinese contractors rather than spend tens of billions of dollars to build that infrastructure, which is significantly more economically efficient. Additionally, building such infrastructure in the United States could take up to a decade, ultimately leading to a significant increase in the product's final price for consumers. Shortage of trained labor in the U.S. compared to China Decades of serving as a global manufacturing hub have allowed China to build a massive talent pool in the production sector that is almost unmatched worldwide. Today, if a company chooses to manufacture its products in China, it can be confident that the workers involved in production have years of experience in their respective roles and are capable of producing high-quality goods with minimal errors. Even if we assume that tens of billions of dollars were invested in building smartphone manufacturing infrastructure in the United States, finding skilled workers would remain highly challenging. Apple CEO Tim Cook visiting the iPhone 6 assembly line in China in 2014. Image: Tim Cook on X In a 2015 interview on CBS’s 60 Minutes, Tim Cook said the main reason Apple isn’t producing in the US is a lack of skills. "China put an enormous focus on manufacturing, in what you and I would call vocational kind of skills. The US over time began to stop having as many vocational kinds of skills. I mean you could take every tool and die maker in the United States and probably put them in the room that we're currently sitting in. In China you would have to have multiple football fields,” Cook said. Also, in 2017, at the Fortune Global Forum in Guangzhou, Cook once again emphasized the importance of highly skilled Chinese workers. “China has moved into very advanced manufacturing, so you find in China the intersection of craftsman kind of skill, and sophisticated robotics and the computer science world. That intersection, which is very rare to find anywhere, that kind of skill, is very important to our business because of the precision and quality level that we like. The thing that most people focus on if they’re a foreigner coming to China is the size of the market, and obviously, it’s the biggest market in the world in so many areas. But for us, the number one attraction is the quality of the people,” Apple CEO said. Higher labor costs in the United States Producing almost any product in the United States is more expensive than in many other countries, and one of the main reasons is the higher cost of labor in the U.S. According to the Bureau of Labor Statistics, median weekly earnings of full-time workers in the United States were $1,235 in the first quarter of 2026. Meanwhile, the average annual salary in China's private sector in 2025 was RMB 71,590 (US$9,961). In many parts of the world, the weekly wage of an American worker is equivalent to several months of income. Another important factor to consider is that in the United States, the workforce capable of working on a smartphone assembly line is highly specialized and therefore commands higher-than-average wages. According to an estimate by Bank of America, producing an iPhone in the U.S. is technically possible, but “iPhone cost can increase 25% purely on higher labor cost in the U.S.” However, this 25% increase applies only if final assembly is performed in the United States while components are still sourced from China or elsewhere. In this case, the price of a base iPhone would rise from $799 to around $1,000. But in another scenario, if Apple were to produce the required components for the iPhone within the United States, production costs could increase by more than 90%. Trump’s dream for a “Made in the USA” iPhone might never come true In a free-market capitalist economy, one of the primary responsibilities of any CEO is to maximize profit. Using Apple as an example, Tim Cook’s role is to maximize the company’s profits so that it can fund research and development for new products and invest in areas such as artificial intelligence, while also keeping shareholders satisfied. Therefore, it is entirely understandable that Apple would choose not to bring its manufacturing back to the United States and instead keep production in countries where labor is cheaper, and products can be manufactured at a lower cost, thereby maximizing its profit margins. What is your opinion about manufacturing smartphones in the United States? If you are an American citizen, would you be willing to pay hundreds of dollars more for a smartphone made domestically in the USA? Let us know in the comments.
