Hi all, While I'm not super knowledgable I have been building my own for years with no issues, so here goes:
PC was running (It is almost never shut off) I noticed a wierd, intermittent buzzing noise that I managed to trace to the PC. All the fans were running the unit was working flawlessly and I really couldn't identify exactly what/where the buzzing was located. Overnight the PC clearly died. I hit the power button to nothing. MB light(s) on, but power botton might as well not be connected. Nothing; no sounds, no anything, not even a minor spin on anything. played with the obvious (plugged in and yada yada all is good. I put a new power supply in (Brand new never used) and same results.
After taking everything apart I used a DVOM to test the power supply and could find nothing wrong there. Did the jumper, fan runs and all voltages are withing spec. Dusted everything and noticed the video card fan is 'stiff' it doesn't turn freely by hand and it is noisy when you do this. However it was spnning when I checked for the noise.
I have a PSU tester coming to verify my results there but I'm stumped. I can't see or smell anything that appears burnt or fried. I was going to put it back together without the video card to see if it powers but I'm not sure that's worthwhile except for personal satisfaction. Unit was built in mid 2009 over the top noctua CPU cooler and case fans galore.
Any advise anyone can provide is greatly appreciated!!! Thanks!!
