My PC keeps rebooting!

[crelm1974]

This all started when one morning I noticed my computer rebooted in the middle of the night and it was stuck at the part of the boot process where it decides whether to boot from primary HD0, floppy, CDROM, etc. At the same time I noticed that one of my CPU fans bearings was causing it to rattle and not spin correctly. I discovered that the boot order was not set for HD0 so I changed it back. This worked and it would load windows but it would only stay up for a short while and then reboot itself. I bought a new fan because I thought it might be the heat causing the reboots. Everything worked fine for 1 1/2 days and when I got up in the morning it was back at that boot section of DOS where it says "Verifing DMA pool". I turned the computer off at the power supply switch and waited ~3 minutes. After doing so I turned it back on and it loaded windows. I was able to get into Explorer and about 2 web pages and then everything locked up and no input from keyboard was being accepted. I turned off the computer again and it stopped at the "verifing DMA pool" part again right where it decided whether to boot from floppy, HD0, etc.. I checked the BIOS and my primary boot HD0 was disabled so I enabled it. Now it will load all the way up to the Windows XP screen and then after seeing it for ~4-5 seconds you see a flash of a BSOD with white memory register numbers and it REBOOTS!. Now it just does this every time. My Mobo is a Abit VP-6 w/ 2 X P3 @ 933mhz with 512 RAM and lots of fans to cool it. Could this be voltages? Bad memory? Virus? Any ideas?

Sounds heat related. I would first; Make sure the cpu fan, and vid fan are turning, as well as the PSU fan. If they are, I'd pull the cpu, and clean/then aplly thermail paste again. Could also be a corrupted bios due to heat? Not sure on that 1.

Mine started acting similar a couple of weeks ago. I noticed that when it did complete a boot I was short some memory. I had 1 stick only showing up as 128 instead of 256. When the memory showed up as 256 it would run fine for a few minutes to serveral hours then reboot. RMAed the memory waiting on replacement.

Good Luck

Thanks for the advice. I did notice the vid fan spins but has a periodic hiccups. The blue screen/reboot happens at the exact moment that my desktop should display in the boot sequence. I fear it might be my vid processor or card thats forcing a reboot. Or maybe it's fried. :frown:

Thanks,

You need to replace the video card fan/ stuttering sure isn't going to cool it.
