i have an amd xp 2800 clone and it has been down for some time. at first i thought that the mobo was ba but now i'm not so sure. when i turn on the machine the screen stays blank (it doesn't turn on), and i don't hear the mobo beep. i have taken it apart numerous times, and can find nothing apperently wrong. my ps has a small 4 pin plug hooked to the board, what is that, and can i use a name brand ps form a dell? please reply fast!!!
