I started having problems with my comp a couple days ago. I would boot up my comp and after a couple minutes it would lag horribly. I looked in task manager and it says that one of the system svchost.exe's is using 99% of the cpu's power. If I end the program that's causing my comp to lag, my sound stops and the graphics reverts to a crappier setting. I have no clue what's wrong. Is it a bad driver or a virus or something? Hope someone knows how to fix this. Thanks folks.
