Please log in for more thread options physical drive, a PCI video card, and a DVD burner. I used my Windows XP installer to load Windows after nuking the drive. The machine has been working fine for the most part, until this last week when it restarts all by itself, over and over. Even Safe Mode restarts. The OS isn't crashing, but something is telling the machine to restart. The monitor goes black, I get the No Signal Detected message from the ViewSonic LCD monitor, and then it keeps restarting. What could be causing this? A loose connection? A broken wire from the switch on the front bezel? Thanks! | |||||||||||||

>What could be causing this? A loose connection? Loose connection is possible, pull out cards and inspect contacts (including memory), unplug power and data cables (also inspecting contacts as much as possible). When reinserting cards, use a flashlight to look at the contact edge to be sure they're seating far enough into the slots. >A broken wire from
>the switch on the front bezel? That is not likely to cause this, unless in the unlikely case the wire was floating around in the system and shorting out on something else. If you have a multimeter, monitor voltage levels. Had you used the system much or at all before performing the upgrade and if so, did it exhibit the problem at all ever? I doubt you'll find anything but check Event Viewer logs. Examine the board for failed capacitors. If all else fails, unplug the PSU from AC for a few minutes then open and inspect it for failed caps (or anything else you might notice). It appears to use a std. ATX PSU, if you have a spare that's known good/working you might swap it in. It would need be new enough to have ample 12V current capacity, perhaps at least 14-16A but even more would be typical. Check for failed fails. If you have a spare video card try it. Pull out all things you have added (especially the memory) and retry system. | |||||||||||||

> LOL > > Failed fans. Thanks for all of these tips. Every thing is fine for the moment, but I noticed all I have to do is move the case and it restarts. Very touchy. It's got to be a loose connection of something shorting out. I'll go over your notes again and see what I can find. Thanks again. | |||||||||||||
