Hello all,
My homebuilt PC, which has worked fine for a couple of years, suddenly isn't working after I cleaned out the pounds of dust from inside it.
During POST process, the BIOS/RAID controller seems to identify the hard drives properly (I'm running two pairs of RAID-1 mirrored SATA drives) ...and I think it's not the drives anyway because of the last bullet-point below.
System goes through the BIOS part of the startup without problems but then either shuts down or reboots almost immediately:
* If I try to boot into windows, it shuts down after a couple seconds of the "blinking light" moving from left to right on the first Windows screen.
* If I try to boot into safe mode, it shows a long list of drivers on the screen, the last of which I believe is mup.sys, and then says at the bottom center, "press ESC to cancel loading VAX347B.sys", and then crashes. I doubt that VAX347B is the problem, however, because of the following:
* If I disconnect all hard drives from the system and boot from a Windows XP CD, it shuts down or reboots when screen says "Windows is inspecting your hardware configuration."
During the cleaning process, I removed the CPU fan, cleaned it and replaced it. Someone suggested to me that if it weren't back on exactly right, that could cause the problem so I took it off again and put it back on and the computer then worked...for two days...after which all the symptoms returned. I don't believe it's overheating because the crash will happen 15 seconds after starting a cold computer (though I suppose that doesn't mean the computer couldn't think it's a heat issue.)
When I was restarting the PC after the original cleaning, I thought I heard my UPS make an odd noise as if turning on the PC caused a sudden (bad) power draw...and I thought I smelled something burning. It was very faint. I moved around some cables and tried again and that issue went away, but that certainly could have caused a problem...I just don't know what problem.
When I boot into BIOS setup, the computer will run without stopping. When I go into the BIOS monitor sections for voltage and for temperature, all readings seem to stay within very narrow and normal ranges.
Any thoughts on this would be GREATLY appreciated!
