CPU Maxing Out at 100%

March 29, 2006 at 00:58:38
Specs: Win XP Pro SP1, Athlon XP 2400 / 1.25GB 3
I seem to have a problem with my CPU utilisation maxing out at 100% and staying there whenever anything that uses 3D graphics is open on my desktop.

System:
AMD Athlon 2400+ (Not overclocked)
1.25GB DDR 333 RAM (Not overclocked)
Windows XP Pro (SP1)
2 HDD (One is 80GB one is 200GB)
Sapphire Radeon 9950 256MB (Unlocked to a 9600 but not overclocked from there)
Belkin Wireless keyboard and mouse
One PCI card (Wireless Lan adaptor)

The problem's started occuring over the last week or so (I installed the new graphics card over a month ago). Whenever I open a game or application that uses graphics (examples include Homeworld 2, Empire at War, Football Manager (which is 2d graphics), or even ATITool (which just features a spinning cube) ) the CPU maxes out to 100% and I struggle to use the mouse or keyboard etc. Some of these games aren't that new and used to run just fine on my old Radeon 9200.

I've checked all the obvious things (spyware, viruses, rouge processes etc), I've dialled down the clock speed of the graphics card to below the manufacturers standards, and I've removed all graphics card drivers and installed the latest catalyst drivers.

It's driving me crazy. Can anyone help?

"Whenever I open a game or application that uses graphics (examples include Homeworld 2, Empire at War, Football Manager (which is 2d graphics), or even ATITool (which just features a spinning cube) ) the CPU maxes out to 100%"

I own an Radeon 9500 mod 9700 360/585, when I open ati tool to show the 3D view, it also use 100% CPU, there is nothing wrong with that. As long as the programs you open yourself ultilize 100%, I see nothing wrong with that. For example, I open homeworld2.exe and it uses 100%, it is normal... What is not normal is when yo open homeworld2.exe, it uses 10% and some other background program like xxxx.exe uses 90% or without open any program, the CPU ultization is 100%, then either you have sypware or virus on your computer... What I would do is whatever you install a new graph card, always uninstall your old drivers before installing new ones. Go to www.ati.com to download the latest driver for your r9600...

Thanks for the response. I would expect a game to use a high level of cpu, but not to the point where the mouse and keyboard stop responding WITHIN that game. That's just silly on a system with this much power.

Try OC your processor and see if that helps.
