So my desktop died last night. I'm trying to diagnose the problem before I go out and buy new hardware. To give a little relevant background, I'm running (or was running) an Athlon XP 2000+ on an ECS K7S5A (rev. 2, I think) motherboard.
Basically, I got back to my room and my computer was off. I didn't remember having turned it off. I pressed the power button. Nothing, no sound whatsoever. My first thought was that it was a power supply problem, so I went out this morning and bought a new 400W PS. Didn't help.
Then I tried unplugging basically everything (IDE devices, etc.) except the motherboard itself to see if it would at least beep at me. Even took the RAM out. No response. But the interesting thing is that sometimes -- seemingly randomly -- when I press the power button, the CPU fan spins for a split second, and then stops immediately.
Since I've tried a brand new PS, I'm guessing that's not the problem, and since pressing the power button does make the fan spin slightly sometimes, I figure it's not a problem with the wiring in my case. Therefore it seems to me that the only thing left is that my motherboard is done for. Is this right? Is it possible that there's anything I can do to salvage it (e.g., would clearing the cmos help?). Granted, a new mobo isn't too expensive, but I'd like to know if there's something I'm not thinking of before I go get a new one.
Also, this is the second time this has happened to me using my current power supply. Is it possible that even if the power supply itself isn't fried, it's frying my motherboards? Second time in less than 3 years. First mobo was an Abit, and this ECS was touted to have "rock solid stability," but a year and a half doesn't seem that rock solid to me, so I'm wondering if this could all be the result of a bad power supply.
