My desktop was randomly restarting for a long time. Re-installed windows XP, new hard drive, new memory, new power supply, new fan and thermal paste for CPU, even new DVD drive and nothing fixed it. Seems to pretty much only do it when I am watching videos online. It used to shutdown and all i got was a No Signal message on my TV I'm using as a monitor. However all my fans were running almost like there was no video signal. I took out my video card and switched to the on-board video, still restarts but no more No Signal message. The weirdest part of all this is I can watch movies all day off of my external drive with no problems, seems to only be while online. I typically use Chrome but tried IE to see if it was that but still no luck.
Quick system run-down just in case:
Intel P4 3.0Ghz HT
Intel D865GBF board
WD 80 GB SATA HD
2.5 GB RAM in dual channel (1 1GB and 1 256MB stick per channel)
Nvidia GeForce 5200 256MB video card
LG SATA DVD-RAM
Not sure what else to put. If anyone has ANY ideas on something to try it would be greatly appreciated.
