100% core utilization in vista

I recently built a new computer and decided to try out vista (LOL FAG). I obtained an OEM copy from a tech shop in town, and ever since I've installed it, one of the cores in my athlon fx2 6000+ is always at 100% utilization. even sitting on desktop with no services running besides the default windows ones, it's always maxed out. I have all available drivers and updates for windows and my hardware, and microsoft is of no help since this computer isn't a dell or HP system. Anybody got any ideas as to why this is happening, or how I could fix it?

U VISTARD!  U NAO HAFF VISTAIDS!  UR VISTARDATION HAZ LED U 2 DIS END!  DIE DIE DIE B4 BILGAYTES AZZFUKKS U MOAR!

realize that FX2 6000+ is not an AMD model and does not exist. Realize vista = fail. Realize ur an idiot. go jump off a cliff. problem solved.

Must be one of those phantom processors.

vista = epic fail

Vistards!  Your Vistaids infection resulted in Vistardation!

Never tried Vista.  Keep hearing it really sucks.  What the hell is supposed to be so great about it that'll make me want to leave XP?  (Or win 95 for that matter)

>>7 dont leave xp, and if your leaving xp then go use ubuntu or something else since vista has this DRM thingie ( you might want to read this page http://badvista.fsf.org/what-s-wrong-with-microsoft-windows-vista ) basically it tries to control you :(

What computer was the OEM for. Please tell me it was at least close to the same brands as your hardware. If not there-in is your problem. OEMs are only meant for the computer they where originally on. This is a bigger problem with Vista as opposed to XP.
