computer randomly shuts down
Posted on 2008-10-01
I have a problem with a computer that was reported to me as "randomly shutting down" by one of my users when doing random things such as reading/deleting e-mail, etc. This is a Dell optiplex GX270 w/ Windows XP Pro sp 3 I have been trying to duplicate the problem seem to have figured out a sure fire way to duplicate the problem. If I go into device manager and start randomly expanding the + signs on seemingly any devices, I hear the hard drive give one hard spin, the monitor light turns amber and the display turns off.
Oddly, the light on the front of the tower itself always stays green and never really "reboots". It just makes the hard drive spinning sound and acts like it is rebooting but never really does do anything accept black out the screen. I also notice that fairly regularily if I start browsing for computers through "My network places" on my network, this tends to cause problems but only rarely. I also don't seem to have any problems brosing the internet.
I don't show any problems with devices when just looking at device manager, and all fans look to be spinning fine in the PC itself. The one thing that for sure causes the problem is me clicking around pretty much anywhere repeatedly in device manager. Any idea what the problem could be here?
