I built myself a new computer a little less than a year ago and I am experiencing the following problem:
It will randomly shut off by itself, with no warning. Its a complete power shut down.
DFI LAN-Party board
Foxconn nVidia 256mb video
I cant for the life of me figure it out. It was on non-stop for three days without a signle problem. Then I shut it down for a night, and the next morning I try to turn it on and it would load windows, let me log on, and then shut down. sometimes it would only stay on for a minute, sometimes it would stay on for 20 minutes.
Ive cleaned all of the dust out of the fan parts/heatsinks for the RAM, video, and cpu. I even took the heatsink off of the the cpu, cleaned the grease off, and re-applyed it.
I set my bios to disable any of the heat warnings/automatic shut down.
I cant for the life of me figure out whats going on.
its been running this exact set-up, error free, no heat problems for a little under a year.
I followed the directions to a tee on the arctic silver compound that I used on it. I dont see any squeezing out.
I guess I'll take the motherboard out and try re-seating it all and seeing if that helps. The only reason that I dont think thats the reason is because it will turn on usually for a few minutes and then just POW its off. Ive looked at it from start up to random shut down to see if any fans werent/stopped spinning and the answer is no. Ive even plugged in another case fan to help out the process.
The powersupply cost me about 60 dollars at the local Altec store. Its a logysis brand.
I took every component out of the case and set it aside (inlcuding the motherboard), dusted everything including the mobo.
i re-set everything individually and let sit for 5 or 10 minutes each.
Nothing individually failed, but everything together I seem to have problems getting the screen to come up. All of the fans are powered on (I can see LEDs or them spinning) but none of the other perhiphrials seem to be getting power. I cant hear the harddrive spinning, and the cd rom doesnt open or close.
This is very frustrating. I am but a lowely fireman. I don't really have money for many new parts.
