*PLEASE READ THE RESPONSES IN THIS POST SO YOU DON'T POST DUPLICATE SUGGESTIONS, THANKS! Very Happy*
I am working on a computer I built a little over a year ago for a customer. About a week ago the owner says it just would not turn on at all. He wanted it fixed, and for some new upgrades to be installed. I looked at it and it seemed like the PSU was dead, but even when I tried it with a tester PSU it still wouldn't come on. I unplugged ALL peripherals, and removed and re-seated the video, sound, and RAM. After that didn't work I tried unplugging every thing including the optical drives and HDD... still wouldn't turn on with just CPU and RAM installed. (usually it will at least turn on with just that even if it gives you error beeps) I checked to see if anything was grounding the mobo or anything else, there are no blown capacitors, I reset the BIOS by pulling the CMOS battery, still nothing. We've already ruled out the power switch by pulling the case leads and using a flat head screw driver to make contact on the power jumpers, and we replaced the power cord from the wall the to PSU. (yes, there was power to the wall socket, it was plugged in, and the power switch on the PSU was ON Wink lol) I also pulled everything out of the case and assembled it thinking maybe the case was somehow grounding it. When you turn off the system you hear that faint kinda pitched power down noise that you hear sometimes when you pull the power cord and press the power button to drain residual charge from the board... so I know it's getting power. (if your a tech you'll know what I'm talking about) After all this I ordered a new PSU, motherboard, video card, and CPU as upgrades/replacements. (I thought that the mobo or CPU was dead) Now, even with a new CPU, new Mobo, new PSU, and new video card... IT STILL WON'T POWER ON! Oh, and then I even repeated all of the above steps with the new parts. ANY SUGGESTIONS? I'm at my wit's end!
