Windows 7: Dell Optiplex 755 randomly restarts

Dell Optiplex 755 randomly restarts

Hi All, as the title says I have a Dell OptiPlex 755, with a clean install of Windows 7 64 bit. I have been having a lot of problems getting this thing to work correctly. I will list each problem below, and separate them:

The first problem I have been having is an immediate restart when I woke the computer from sleep. I would get a flash of the login screen, and then the system would reboot. Doing some research, I figured out a couple of settings to modify in Windows. I disabled Wake timers, Disabled Hybrid Sleep, and I unchecked "Allow This Device to Wake The Computer" for the Ethernet adapter. Without installing any Windows Updates, ie, right after installation, the computer would sleep and function normally.

The second problem I am currently having is a very similar problem as before. At this point, all the mandatory Windows Updates are installed. What happens is when the computer is woken up from sleep, and sits Idle for about 45 seconds to 2 minutes, it will shut down, and then turn back on. I have no idea as to why the computer is doing this.

I have used memtest86 all day today testing the ram, and that is not the problem. I have not ruled out the mobo or hdd yet. I have also looked through the event logs, and I get a critical event 41, and in the error section I see errors 10, 6008, and 7023. I do not suspect events 10. I will post the details for each error below.

I really hope one of you guys can help me; this is without a doubt the hardest time I have ever had getting a computer to work. I am getting kind of frustrated with this. Any ideas are very sincerely appreciated. Thank you.

Problems like this indicate a issue with the power supply.

Have you tested your power supply?

PSU - Test DC Output Voltage

Have you tried a new power supply unit?

Hi andrew129260, thanks for your reply. I took the computer into a local computer store, and they discovered the hdd went bad. I bought a new one and tried it, and it didn't really cure anything.

However, I've noticed something peculiar. When I leave my ethernet cable plugged into the computer, the computer resumes from sleep, and will restart within 1 minute. BUT, if I leave the ethernet cable unplugged, put it to sleep, wait 10 minutes, and resume it from sleep, the computer does not restart. I sat and watched it for 10 minutes, but it just stayed at the login screen, and it behaves normally.

I assume this is a windows problem; but what?

Have you double checked the "Allow this device to wake computer" on the Ethernet adapter since you ran the updates? It may have reset itself.

Hi Mellon Head, thanks for your response. Yeah, I have double checked the Ethernet settings, and the "Allow this device to wake this computer" is unchecked. I have tried with it checked, and it does the same thing.

I am beginning to suspect the power supply is bad. Could this be the problem?

Unfortunately the only real way to check a power supply is to substitute a known good supply. Considering the age of this model the power supply is suspect.

There are 4 different versions of the OptiPlex 755. On most (all that I've seen) of Dell's compact case (Small Form) models they do not use a standard ATX power supply. There are TFX power supplies that are used on many compact case models. The full size case models are BTX style but use an ATX power supply.

Hi fireberd, thanks for your reply. I ordered a power supply for it, and also a power supply tester so I can test future ones. I will report back with my results when I place it in.

No guarantee that the power supply is the problem, however as I mentioned unfortunately the only way to fully test a power supply is to replace it with a known good one.

As far as the "tester". That only shows voltages under "no load". A power supply can test good under "no load" but fail when it is hooked up and "under load".

Hi fireberd, thanks for the advice. I still think a tester would be handy, and it could help guide me in a direction in future situations.

I know there is not a guarantee with the PSU, I am out of ideas on the issue. I have changed Windows settings, and it still isn't working.

Another reason I think it is the PSU is because of the ethernet adapter issue. While a Windows setting could cause this problem, there are not very many settings to try in device manager, and I have tried them all. This tells me that it is most likely hardware, at this point, and not software, especially considering it runs fine while the ethernet cable is unplugged.

Hi all- i put a new power supply in, and it did not cure the problem. I can now officially rule the power supply out as the problem.

I am going to retest the RAM with known good RAM from my personal computer. If the computer functions as it should, I will know the RAM is bad, and if it doesn't, I will rule the RAM out as the problem.

After that, I will test the HDD using seatools. If the HDD passes, I am not sure where to go from there. I have screwed with Windows settings, and cannot get it to work.

I might try installing Windows 7 32 bit, but what I have on it now, Windows 7 64 bit, should function just fine. If this does not cure the problem, I might just say the heck with it and swap the mobo.

Could anyone point me in a good direction, I feel like my ideas i've laid out here are literally a "shotgun" method to diagnosis, when I would rather just focus in on the problem. If this is the only way to do it, then so be it. Thanks for anyones reply.
