i would like to share this with you.i have the gigavyte 7n400-l mobo with a amd athlon xp 2600+.the videocard is a 9700 pro and i have two sticks of 256 mb ram. the weird about my system is that when the processor works or/and the hard disk works a strange BZZZZZT can be heard all the time the process/execution is happening. it sounds like its coming from the hard disk or from the mobo itself. it feels like its something in the electronics of the mobo or whatever. Another clue is that when i am running prime 95 you can hear all the time it executes the processes the BZZZZT it makes my system. do you have any clues on what maybe causing this unheard phenomenon?????
