Solve : Ramdom reboot? |
|
Answer» DELL Dimension 5150, Windows XP home SP2. Here is a puzzler for you. It is driving me crazy. About 3 months ago I got up one morning to find my computer was on, I shut it down but after a few minutes it rebooted its-self. I pulled out the plug. Later it booted up normally but after about an hour Windows shut down while I was working and immediately rebooted only to shut down again and continue in this loop until I pulled the plug again. Sometimes I could work for an hour, sometimes only a few minutes before this would happen. The computer would also crash in the BIOS at this point and as all anti-virus software was up to DATE it was thought to be a hardware problem. The CPU fan was changed to no avail. I took the computer to an IT colleague. He ran the computer with all removable stuff taken out but the problem persisted. He tried a different processor and wow! it worked ok but strangely when he put my processor into another computer it also run ok. He then reassembled my computer with the original processor and everything was fine for a couple of weeks. Then the whole thing started again. I took Windows Media Player back to an earlier version as this had been updated around the the same as the problem first stared and surprisingly Windows no longer shut down while I was working. However the booting up on its own problem persisted and I had to pull the plug to stop it HAPPENING. I checked and remade all connections within the computer but I didn't find anything loose and surprise, surprise everything has been fine for weeks...until last night when the computer booted its-self up again. I shut it down and it booted up again. Here we go again. The only thing I did yesterday was update virus definitions from Semantec. Help!!maybe you could look in the BIOS and see if "Wake On LAN" or "WOL" is enabled. Also, when you shut down do you shut down completely or just suspend or hibernate? Not sure how to do that but I will look into it, thanks. Could the CMOS battery have anything to do with it? Computer is only 2 years old. I always shut down completely by the way.Could be. Could be (sorry to be blunt) crappy Dell parts getting flaky. Well that is certainly the cheapest OPTION. I will try that first. Thanks again. |
