Solved Stutter

I have a clean install of vista home premium 64-bit and every time I try to run an app or game it freezes and unfreezes so bad you can't access the app to shut it down.Anyone know anything about similer problems possable fixes I have no Idea why this is happening there is almost nothing but windows running in task manager like I said I did fresh install because of this behaviour with the oem 32-bit version of home premium.I am so tired of trouble shooting windows 4-gigs ram 2.4 quad core.

okay so I read about some virus tools that were suggested on this forum and ran malwarebytes (already use ccleaner)it picked up one file called something like hijack video display.I have no idea what this is anyone familier with this kind of thing.I was wondering if the free version removes these infectiouns?

WOW big differance start up is faster sidebar not hanging and crashing at startup great programe guess this thread should be closed.
