Graphics Card: Diamond Radeon HD 3650 1GB/GO DDR2
Power Supply: 300W

After installing my new ATI 3650 card my core 2 processor is continuosly
ranging between 90 and 100%, while core 1 is running normally between 0 and
10%, yet my memory usage is only ~35%. Additionally, the system is running at
~58 degrees F.

I checked my other drives and partitions where I'm running Win XP media
center edition and Win XP Pro and both cores are running normally with both
OSs. I also switched processors, 3800+ and 4200+ (939), and the problem is
exactly the same with each. Also, I've un-installed / re-installed drivers
and CCC, and completed a full memory test with and without the HD 3650 card
installed, no errors.

I've attempted to gather the latest drivers, bios, and everything else I can
think of, yet nothing has altered this strange behavior. I really don't know
if this is a Video Card problem or a Vista problem but I suspect a Vista SP1
problem since everything is normal when using XP. Any help resolving this
problem will be greatly appreciated.
