I've come to this area for help before, and it was good, so I shall do it again \o/
So I accidentally left my computer on all night running Mount&Blade. Shouldn't be a problem but every bit of info helps. I turned my computer off, and in doing so XP installed an update. About 5 minutes later I turned it on again.
It will not boot. There is no beep. The video card driver spins at a high speed and stays there. Cpu fan works, PSU fan works, lights, other fans, temp reader are all on. I hear the HD and the DVD drive making acceptable and normal noises. It will not restart using the reset button, the only way to turn it off is the PSU switch or holding the power button.
- but the HD access light doesn't come on. This fact and the fact that windows installed an update right before the problem makes me think it might be a hard drive problem. I have no way to test that, though.
- I'm a little ignorant when it comes to PSU's, but I looked at it anyway. using a voltmeter on the Molex pins gave a reading of 6.3. I don't know which rail that was or if it is significant. The fan in the psu spins and there is no burnt smell. It and the HD are the oldest pieces of hardware in the computer.
- Tried resetting cmos
- Tried a different video card
- Ram is fine
- I don't know if it could be the motherboard or not. The symptoms fit, I guess, but I don't know of a way to test that really. all the fans and lights work, so I'm guessing it isn't? Or maybe hoping.
So, there is my problem. To me, the most likely thing is the harddrive, but all the sites i've been to don't list that as a big cause for a computer not booting. The power supply is listed as a big cause, and again the voltmeter said 6.3. Not sure if that's okay or not. Removing the video card (I understand an 8800gt is pretty power hungry) made no difference.
So, there you have it. I humbly ask for your opinions before rushing off to my local NCIX and vainly throwing money at things.
VVVV Yes, a different video card made no difference.
