Dell Optiplex 760 random reboots

June 30, 2009 at 14:48:01
Specs: Windows XP, Core 2 Duo/ 4GB

Hi, I have about 60 dell optiplex 760's and have been having issues with random reboots with a handful of them. I also have other issues where the monitor will go black (nothing) for a few seconds when clicking on anything that will change what might be on the screen. It stays black for just a few seconds and then comes back. The big issue is the random reboots that occur. I am wondering what I can do to fix this???? I have XP running SP3 and BIOS is set to ATA.

Start by disabling the auto-start feature, then instead of rebooting, you'll get a blue screen error meassage that *should* help you to troubleshoot the problem.

I am having the same issue, we just received our fourth or fifth 760. I am not seeing any information in the event log and my auto restart is not turned on. Do not get a standard Blue Screen. I am thinking electrical. I am still swapping different parts to see if it will stop, but the reboots are so random, sometimes it 2 hours sometimes 6 or 7.

I know what you mean. It seems to be very random with the reboots. I also noticed that when the pc goes to sleep mode after some time, a few of the computers do not want to wake up from the sleep mode either. I found that if you hit the space key like 3 or 4 times really strongly it will wake them up??? go figure, have to beat a pc to get it to work:) j.k.

I just wish I could narrow it down to a specific driver or hardware that is causing this problem. I image my machines with XP SP3 so all 60 computers are identical. This makes me lean more towards hardware issues with dells, or incorrect drivers somewhere to where I am noticing problems with a few acting up due to a driver. I have been troubleshooting this for a few weeks now with nothing. Dell has replaced a few of the motherboards and a few RAM chips since there were a few bad ones we got. My guess at this point would be faulty parts. There is always one or two bad eggs out there....maybe we were just lucky enough to get the bad eggs....

Your symptoms indicate faulty power supplies. It's possible that the machines with the problems were built with a bad batch of power supplies.

Hi we have been having the same problem with our 760's. We have also had one 755 and a handful of 620's all doing this same thing. What virus scan are all of you using, and would anyone happen to be using any software that is out of the ordinary? On a few tests we found that Entrust was crashing right before the sporatic reboots occured. If anyone has some more info on their version of the problem it would be greatly appreciated.

I have a bunch of 760's that are randomly rebooting. We have narrowed it down to a power supply issue. The model # of the power supply is F255E-00. These are supposed to be an energy efficient power supply.

Does anybody else have the model #'s of theirs??

I am having the same problem with random restarts on dell optiplex 760...mouse becomes unresponsive and then screen goes black and machine restarts. I would like to try jam's suggestion but I don't know how to disable the autostart feature...is that the same as autorun? Thanks for the help
