Hardware diagnosing question...

I have a new build that I got last Thursday in the mail. I assembled all the parts and installed Windows 7, it would boot up fine then it would BSOD on me every now and then.

I thought it was the RAM, at first. I find it a lot more common for that to be the culprit for the random BSOD issue.

I ran Memtest86+ twice and it came out clean. I was puzzled for a second.

I bought an SSD drive for this build and I've seen reviews in general that some SSD drives can be faulty, that was my second thought of why it was happening.

I put in an HDD and it ran fine... For a while. Now it won't even turn on at all.

Now, before all this happened I had run a Prime95/Furmark CPU/GPU stress test, lasted for hours fine.

I recall something odd happening with one of the stress tests with the CPU (I ran several). On one of those tests I clicked "stop" on prime95 and as soon as I clicked OK the whole computer froze. Not sure if it has anything to do with what I'm about to say next.

The bottom line is that I'm not sure what to RMA next. The motherboard or CPU? I know that the computer won't turn on if the CPU is faulty... what do you guys think?

Specs:

Processor: Phenom II X6 1090T

Mobo: ASUS M4N75TD AM3 NVIDIA nForce 750a

RAM: Kingston HyperX 3GB (3 x 1GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) KHX2000C9AD3K3/3GX

PSU: OCZ Fatal1ty OCZ550FTY 550W

GPU: EVGA 01G-P3-1371-TR GeForce GTX 460

SSD: OCZ Solid 2 Series OCZSSD2-2SLD120G 2.5" 120GB SATA II

Well, fault could be at anything actually. My best guess is motherboard at this point.

Can you list your specs? specifically power supply, as that could have been an issue.

Do you have a speaker on your motherboard?

The best thing to do is try parts on other computer, Except PSU, you don't want to risk anything with that.

For now, give it a rest, and try to power it on in maybe 30 minutes with only MINIMUM connected (1 ram stick, no HDD SSD or ODD, no fans, no graphics card), meaning the power supply will only give power to the motherboard (24 pin and 8 pin)

The freezing most likely signifies hard drive issues from my experience. Otherwise the crashing could be memory, and not it being faulty but rather undervolted, check to make sure the motherboard is giving the right voltage to the ram that meets the rams required voltage, my 790i undervolted my ram and that cause lots of crashing.

Well like I said, when I could at the time I tested the RAM. And it passed the test twice on Memtest86+ (latest version).

I have a power supply tester and the PSU tested ok on the voltages.

HDD/SSD are fine, it was known working HDD from another computer. Plus I used the SSD on another computer for a day and it never crashed. It's not the storage either.

I do have a speaker for the motherboard but it's detachable and I haven't put it on. Thanks for this tip, I will try to see if the speaker gives any beep errors tomorrow when I have time.

Update:

I put on the speaker but now it actually turns on again. Except it keeps crashing every now and then, giving me inconsistent results. Right now what I can make it do is have Prime95 open and every time I do a blend test it crashes immediately.

What could this possibly mean? Is it pointing to a processor problem or motherboard?

Then again, even if I'm not running Prime95 it will crash in the middle of loading windows sometimes or just opening my web browser.

What do you guys think it is?

It could be ANYTHING. I actually had the same problem with the build I just did for my girl, and you know what it was? A pci slot USB 2.0 card that plugs into the empty spots on the motherboard. I had even used this previously working just fine. For some reason it won't work without crashing in her computer. So, as I said, it could be anything. You will have to remove or swap one device at a time and test the results

Sometimes I get BSOD's sometimes I don't and the computer completely freezes.

The only thing that's attached to the motherboard is the video card, cpu, 1 stick of RAM (which memtest86+ tested good), and a keyboard (not even a mouse).

I'm thinking of RMAing my motherboard... any other suggestions?

you are looking at the wrong part being faulty

Then what do you suggest, wise one?

Anyway the only things that are plugged into the motherboard are the GPU,CPU,1 stick of RAM and a keyboard. (Not even a mouse is plugged in).The motherboard's RAM checker says the ram is ok (makes sense considering Memtest86+ also told me the RAM was fine.)

I have already updated the BIOS and resetted to default settings more than once.

Update: It was the motherboard.

I've never had a motherboard do that to me.

Motherboards usually WORK or the DON'T WORK at all. Never halfway in between.

Anyway, thanks for the suggestions.

I'm just glad I made the right call, even though it was tricky. :)

    • You pay just $100 per TB with this rare 4TB PCIe Gen4 NVMe SSD deal

      "just $100 per TB"? Just? Are we trying to make this seem like the new normal? Kinda weird to make it sound like that is not a ridiculously expensive asking price.

      The reviews you refer to mean nothing. Where there is no journalism there is no reason to call the gaming media's opinion pieces "reviews". For GP games there is indeed a metric for success - increasing subscriptions. Which turns in revenue. The only circumstance in which subs do not rise when great is being released is a Game Pass system where the company is close to fully saturated with customers in a subscription. However, in that case as the theory goes you spend aplenty in all kind of games - from shady live service cash cows and customer offending agitprop crap in purple colours to robust and entertaining single player games. And keep a solid level of profitability. Ignoring the simply innocuous but mid games MGS has released primarily of the second kind.
    • Report: Microsoft to use AWS to help GitHub deal with a major surge in demand

      By pradeepviswav · Posted

      Report: Microsoft to use AWS to help GitHub deal with a major surge in demand by Pradeep Viswanathan Thanks to the surge of coding AI agents, GitHub's usage has skyrocketed over the past 12 months. To meet this demand, GitHub started with a plan in October 2025 to increase capacity by 10x. However, by early this year, the company realized that it needed 30x scale. This rapid growth has caused severe strain on the platform's reliability, resulting in several small outages over the past few months. In April, GitHub published a long blog post explaining the steps it is taking to resolve these reliability issues. In the post, the company also confirmed that it is working toward a multi-cloud architecture for better resilience. Today, Business Insider reported that GitHub is turning to Amazon Web Services to help deal with a major surge in AI-driven coding activity. It is important to note that GitHub is still in the process of moving completely to the Azure cloud. The current plan is to move the platform fully to Azure by 2027 so that it can scale better as per developer demand. Therefore, the current decision to utilize AWS might be part of a short-term plan to meet immediate demand. A Microsoft spokesperson confirmed that GitHub is using multiple cloud providers with the following statement: For Microsoft, the decision highlights the operational pressure behind the AI boom. GitHub has to stay reliable for developers at a time when rivals such as Codex, Cursor, Claude Code, and other AI coding tools are gaining attention. And the decision to use AWS for computing capacity seems practical given the circumstances.
