Need a few suggestions thrown my way in regards to a desktop pc im trying to troubleshoot.
Here are the problems.
Started a month ago; wouldn't come out of sleep, would just power down as if the plug had been pulled. After a few days of this wouldn't restart after powering off unless I pulled every plug except the power cord and monitor cable, only when Windows was loaded could USB devices be connected. Next problem was one of the monitors (have dual monitor setup) displaying a green tint, then the keyboard (ps2) stopped working, finally plugging a USB drive into front port would also generate a complete power off)
Here's what I have done so far.
Checked RAM, graphics card etc all seated correctly. Check.
Removed graphics card and run from onboard GPU. Check
Removed 1 RAM of 2 and alternated. Check (This actually worked for about 2 days, so thought it was bad RAM module....on the 3rd day, back to square one)
Replaced monitor cables. Check. (Monitor fixed due to using its vga port instead of dvi port, weirdly enough it works with dvi on another PC, again this happens with both onboard GPU and Graphics card)
Replaced power supply. Check.
Installed pci network adaptor. Check.
Replace case. Check (Thinking it was a short on the front USB ports)
I am now running out of things to replace (New board, CPU and RAM next, let's face it, great excuse for a major upgrade). CPU temps are all normal and the PC will actually run fine for days, just won't start if it's shutdown for more than an hour or two.
Absolutely got me beat; my assumption is now the main board shorting somewhere under load, but really that's just a guess.
Love to hear your opinions.
