Optiplex GS620 random reboot, please help

Question

Have 2 new Dell Optiplex GX620 computers at work, Windows XP Pro, Intel Pentium D processor, ATI Radeon 600 video card, and a DVD-ROM and a DVD+/-RW drive. Programs installed: MS Office 2003, Mozilla Firefox 2.0, Internet Explorer 6.0, Adobe Reader 8.0, Adobe Photoshop CS, Windows Media Player 9.0, Symantec Antivirus, Nero OEM Suite. BIOS v. A11 The problem in both computers - sudden and random automatic reboot during the work with no apparent reasons, couldn't associate with particular actions or programs. Usually happens one - twice a day, very annoying, you can lose good chunk of work if you are writing or doing something. I also noticed that the reboot never happened if computer was just idling, say, was just ON during weekend or overnight and nobody used it. Contacted Dell, they advised first to go to msconfig and disable all non-microsoft services, but it didn't help. Then they advised to backup all data and reinstall Windows, which I don't want to do unless no other choice. Any help/ideas?? Thank you. George

did it restart because of a blue screen error or it just suddenly restart?   check the following option:   System properties->advanced click on settings under startup and recovery Under system failure, uncheck 'automatically restart'.   If this checkbox was checked, your system may suffer system failure and restart by itself. If you uncheck this box, you will be able to get  abetter idea what cause the system error. You can also check event viewer for error log.

It restarted without any warnings or blue screen, and no error messages recorded in the event viewer. The box 'automatically restart' was unchecked. Today came technician from Dell and replaced both mother board and power supply. I wasn't present there and don't know details. I guess it was a hardware problem and hope these measures will be enough. The second GX620 computer we've with the same problem was not repaired as yet. I'll keep you posted.

Mother board and power supply were replaced. They (Dell) blame some faulty capacitors that could lead to this problem. So far everything works just fine.

n2ho, did you change memory, add or else before Dell changed things?

n2ho · Answer

I didn't change anything before Dell came. What happened next after motherboard and power supply replacement was the same problem, but happening rarely (approx. once a week reboot vs much more often previously). I call Dell again and they came and replaced the processor and memory (what else left in the computer after all?). Now everything works flawlessly for about 2 months. What caused the problem I still don't know.
