So i dont know if this has happend to anyone but i have a windows xp home computer that i bought in 2004, i had minor problems since then and so on but i have this problem with the computer now.

Whenever im on it sometimes the screen flickers like if the computer is going to die yet i dont have anything else plugged in, i thought it was a virus but i used three virus scanners.

Spybot search and destory
macfee or whatever its called
ad aware

maybe i have to many installed? or maybe i have the wrong ones installed but it didnt pick up anything and my computer screen flickers and it also makes a "buzzing" sound. which isnt that loud it only does it when my computer flickers.

any ideas?
