CPU usage 100% for no reason

I have a PC that that I bought awhile ago and it is 100% perfect according to the vista upgrade advisor app.

I am using my powertogether (MS Campaign) version of vista business(32bit) and it installs without a hitch. but it is laggy. I used actual drivers for vista on my Vid card, Printer Etc. but it is slow and laggy

I used EVEREST home edition to snoop out my specs.

my specs:

Compaq SR1730Z CTO(Custom to order)

AMD64 3700+ Sandiego w/ 1MB cache

2GB PC3200 DDR ram

160GB SATA drive

lightscribe DVD burner (dual layer

no name DVD-Rom

SB Audigy4

ATI x1800GTO 256MB DDR3

ATI Xpress200 chipset (ATI RS482/RX482 northbridge, ATI SB450 southbridge)

Now mind you, it runs nicely otherwise albeit the lag and the task manager telling me my CPU is screaming along at 80-100% usage.

My best educated guess is my chipset doesn't play well. So i spoke to a rep at HP and he said that ATI hasn't released official drivers yet for Vista. no idea when but HP does have Vista added under the support/drivers. So i guess that will come soon!?!

what causes the CPU to run so high when my task manager says it is running at or near 100% the idle process uses like 80% but nothing else seems to come about when i click the "processes by user" button.

any ideas? I like Vista and it was free and otherwise a fun OS to tinker with.

BTW, I tried to use the WEI (windows experience index) rating app and it always gets to the end then says that too much interference causes it to not be able to finish.

Yeah, what Mio said. If you click the Performance tab, your CPU shouldn't be too high (mine's 0-2% idle).

However, CPU aside, memory does seem to be a high-end resource :unsure: With just tasks such as Firefox and Gaim, Vista uses up nearly 1.3 GB of memory. Anybody else noticing this?

Vista actually doesn't use as much RAM as it seems, but it caches your frequently accessed files on startup so that frequently-used apps and such will load faster. This is otherwise known as SuperFetch, and is why hard drives tend to do a lot of "thrashing" when Vista first boots.

If another program actually needs any of this memory, Vista will instantly release it.

The idea here (and accurately) is that free RAM is wasted RAM so Vista tries to use as much RAM as possible.

Nobody seems to get this and reports that Vista uses massive amounts of RAM, and while it definitely uses more RAM than XP, its not as bad as it first appears.

Thank you. That clears that up for me very nicely.

Have you clicked the "Show process from all users" button and then clicked the CPU column header to sort by CPU usage and see which process is using the most CPU cycles?

yeah but, there's nothing showing why other than system kernel which is running like a cat in heat :cry:

    • This hidden Windows 11 setting makes the system feel a lot faster

      By eiffel_g · Posted

      I've set since XP - Best performance in the Performance settings. 11 included. I enable only the show shadows after that, so I can see better fonts and mouse.. But hardly I can say I can see a difference today.
    • Next-gen AMD GPUs reported to support HDMI 2.2 with up to 80Gbit/s bandwidth

      By Paul1979UK · Posted

      Yeah this kinda means nothing to me if it's going to be the same mess as HDMI 2.1 where it was difficult to know what features you were getting. It was way too confusing, designed to fool us into thinking we was getting something better with the higher number when a lot of the times we didn't get anything better because companies can add and remove features at will, which if that is the case for 2.2, then who cares lol.
    • Someone wrote a script to block 'brainrot' content online using an $8 smart plug

      Someone wrote a script to block 'brainrot' content online using an $8 smart plug by Usama Jawad Original image via Neil Chen Many people use smart plugs nowadays due to the various advantages they offer, including automation, integration with mobile software, increased home security, better energy efficiency, and compatibility with other smart products. However, a smart plug customer has gone a step further by enhancing their hardware in a way that it blocks them from viewing "brainrot" content online, or any website, for that matter. As seen in a popular thread over on Hacker News, a person known as "NWChen" has written a script that connects to the $8 Kasa Smart Wi-Fi Plug Mini and utilizes it to restrict access to websites of your choice. In essence, this plug then acts as a physical switch that you can toggle to visit certain websites. NWChen's main motivation behind this initiative was to avoid brainrot, with examples listed as X (formerly known as Twitter), Instagram, YouTube, and Reddit in their blog post. In terms of technical functionality, the smart plug connects to Wi-Fi (obviously) and hosts a physical switch that can be used to turn it on and off. NWChen's script connects to the smart plug via an API and then polls its state. If it's on, websites of your choice get restricted and you can't open them anymore, until you physically get up and turn off the plug, or remove the website from you blocklist. NWChen has recommended plugging in the hardware far away from you so there is sufficient resistance in turning off the plug. In the thread, many have praised this invention, believing that the nature of this mechanism provides enough hurdles where you'd rather just not visit the problematic websites anymore. However, some have noted that "those without self control cannot be trusted if they hold the switch". Some have also highlighted a problem where a user can simply stop the script's execution without much friction. Overall, it's a fairly interesting setup, even if it's fairly rudimentary in nature. Configuring this physical block with a Kasa smart plug is fairly easy. You can simply download the script from the laptop-brick GitHub project here, install it, get the IP address of your smart plug, and then use it when you're executing the script. You can modify the blocklist using a dedicated file present inside the GitHub project.
    • Another win for EU users? Ads in WhatsApp won't be coming this year

      By Paul1979UK · Posted

      We'll probably mirror the EU rule, we've done that in many other areas, but if we don't, well we can add this as another reason why Brexit shouldn't have happened. Personally, if I started to get ads in WhatsApp, that would be a big incentive for me to want to switch to an alternative, and I doubt it will be difficult for me to get my contacts to change as well.
    • Nvidia and Foxconn planning to deploy humanoid robots within months

      By Paul1979UK · Posted

      It reminds me of fossil fuels, as they try to push the price up and renewable energy continues to get better and cheaper, it's putting the squeeze on the fossil fuel industry. In this case, bringing jobs back to modern countries with higher wages would be a big incentive for corporations to remove humans from the workforce and replace them with AI and robotics, and the funny thing is about that, consumers will demand it because they want things cheaper not more expensive, also corporations will be forced to do it if they want to survive against others that go that route. At the end of the day, they didn't pick cheap labour because they wanted to do so, they did so because competition forced companies to do so, bringing jobs back to western countries would make these companies less competitive on the world stage, unless they use a lot more AI and robotics to remove a lot of humans from the workforce. With that said, bringing jobs back to more stable regions and using AI and robotics does have the benefit of reducing the risk of political trade wars and tariffs, but let's forget this idea of jobs coming back home to higher paying wages, that idea is dead in the water with the advancement of AI and robotics, and with humans, it would only end up making a lot more things more expensive.
