When I see a dead PC I usually strip it down in stages. But in your case you may want to go all the way down to just the motherboard and the motherboard on cardboard. If that won't power up then there is one more thing to check. The CMOS battery. If it's too low, some boards will not power up.
Alright, here's the stats on my computer
- ASUS M2N32-SLI Deluxe Wireless Edition AM2 NVIDIA nForce 590 SLI MCP ATX AMD Motherboard
- G.SKILL 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ
- AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000CZBOX
- SILVERSTONE ST1000 ATX12V / EPS12V 1000W Power Supply
- EVGA 512-P2-N773-AR GeForce 8600GTS 512MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card
The other day, I went to power up my computer and nothing happened. It just stopped working. I don't recall any power outages or anything. Whenever I turn the power on to my PSU (not the power button on the front of the computer), the heatsink fan, video card fan, and the PSU fans start up for a couple seconds then stop. After the fans stop, I can do nothing. I try the power button and nothing. No bios. No beep indicating the computer is starting.
I first thought it was the PSU that had gone bad, but I test it on a different computer and it worked just fine. At this moment, I think it might be the mobo or the cpu but I don't want to get another mobo if that's not the problem. Are there any ways I can test to see if its one or the other?
