i have an odd problem with my computer where it seems to randomly start acting up the sund will get very scratchy the internet will get so slow its unusable and my TV-tunner card will start makeing lines across the picture. All these things seem to happen all at once and fairly randomly to. Its not a virus because i just reformated everything in hopes that it was. but the problem is still occuring. I have a built in sound card on a Nivida nForce mother board. an ATI tv wonder VE TV-tuner card and my networking port is also built into my mother board. Any help is apricated
