100% Cpu Usage After Driver Update

Specs: Windows XP Media Center Edition

I've searched everywhere and i just can not seem to fix this 100% CPU Usage. I've reformatted my computer and did everything until i got to the desktop. I Open task manager it showed everything normal again (No 100% CPU Usage). SO i went to update my Graphics card Driver and it suddenly jumped and stayed at 100% CPU Usage. I checked my processes over and over and its all at 0% except the "Sytem Idle Process" Which really doesnt count.

Computer Details:
AMD Ahtlon 3500+ 2.2ghz
1 gb ram
ATI Radeon Xpress 200 Series (Chipset)
200 GB Hard Drive 7200rpm
8-in-1 Memory Reader

Have you thought about adding more RAM to ease the load?

Yes I Have Added More RAM before, but it didnt seem to work.So I Took It out.

EDIT: IT has seemed i have seen something that came back in processes. I found that "System" Ran by system is taking up 90-99 of CPU. The Usage by that only goes down if something else take some cpu
Example:System 70

Adding RAM won't affect CPU usage, but it will definitely improve overall system performance...I suggest you put it back in.

Other than that, it's possible your system is infected. When's the last time you did a full virus scan or scanned for spyware/malware?

ATi's god awful drivers use microsoft .net framework. Until the framework is fully compiled it will use 100% until you the user start doing something. Just force .net to compile, should only take a few minutes to an hour or so. Go bitch at ATi for making crap drivers.... To bad Nvidia's drivers are almost as bad as ATi's now.

I once had an AMD 64 laptop with the X200 chipset and that's what I had to do in order for it to stop using 100% cpu time at idle. Hope it helps!
