Hi, I subscribed to this forum because I've read some posts about bootup problems. I recently ran into this problem myself and was hoping that I could find some advice as to where things went wrong.
Here's what happened... I left the computer on all night, when I woke up I restarted windows, not a full reboot, to refresh the ram. I had been running the computer for about 2 hours, checked my email, did a little bit of searching online, and was running mIRC also. I checked on what I was cooking and returned to the computer to check out what was going on. Suddenly I heard a higher pitched buzz, sort of like the fans kicked in overtime. (Louder version of a fan running) Then the computer just shuts down completely. Everything else on the power strip at the time stayed on including the desk light, phone, and answering machine. I turned off the power supply, let the computer sit for a few minutes and tried to turn it back on. Once again, I got the high pitched buzz and after 2-3 seconds it shuts off again.
After that I unhooked everything from the back, opened it up to see if anything had fried or melted... nothing. I decided to clean it out thoroughly because it definately needed it. I reattached everything in the back and tried again just hoping it was the dust buildup... and again, nothing.
There was a CD-Rom recently installed... so I upped the power supply voltage. It started when I rebooted but the only thing that came on were the fans and the leds. There was no initial beep like all startups, the harddrive wouldn't spin and the CD-Roms wouldn't open. Also the computer wouldn't turn off. The only way that I could get it to shutdown was to unfortunately turn off the PSU. Once it was off, there was a burning smell coming from the Mobo/PSU area.
I haven't done anything since then just because I'm afraid to I'll ruin more components than already harmed. Any help would be appreciated. Thanks.
Oh yeah... all cables are connected securely, RAM and video cards are pressed down completely, I also turned down the voltage on the PSU for fear that it might be too much.
