Need help with PSU again...

post #1 of 2
Thread Starter 
So this time, my friend installed a somewhat cheap 400W PSU in his machine and it worked fine for one day. This morning he went to turn it on and he got an unusual beep, then no video on the screen. I tried to swap ram for him, installed a GPU (he was using onboard video) cleared CMOS, tried a different PSU, everything results in the PC powering on (fans going, HDD's starting up) but then theres no video.

Any clues on what is going on? Any help appreciated. His PC definitely does not exceed 400W since its a Pentium D with 2 hard drives, on board video and 4GB's of RAM.
