First run F12 preboot diagnostics to check the hardware is good:

Upgrade installs in general have issues and reduced performance. I would recommend Clean Reinstallation of Windows 7 or alternatively installation of Windows 10130 to get the free upgrade to Windows 10 Pro (and then clean Reinstallation of Windows 10 Pro after).

Hi Philip. Thank you for your response.

I already did an F 12 pre diagnostic and it found no errors. This is also a clean installation of Windows 7. I'm wondering if a lack of memory could be the problem. The PC has two gigabytes which Microsoft says is enough, but is it? Would upgrading it to 4 gigabytes be a good idea? I don't want to throw good money after bad.

Thank you.

Gary

More RAM will help performance wise but it shouldn't be the cause on rebooting.  Some others have prescribed this behaviour to a bad power supply but the diagnostics should pick this up.

P.S. 

Just to clarify a couple of things...

I realize that a faulty power supply is usually the cause of reboots, but I'm doubting that's the issue since it seemed to be fine in Safe Mode. As I already said, the F12 diagnostics have found no errors at all.

Also, I stated earlier that the PC had 2gb of RAM. That was a typo. It only has 1 gb. (512x2). I want to upgrade it to 4gb anyway, but not if there's something else wrong that would make that irrelevant.

Thanks again for your input. I greatly appreciate it.

Regards,

--- Gary

Hi Phillip,

Thanks again for your response.

The Dell diagnostics are not finding any problems. However, just for laughs, I took 4gb out of another E520 and installed it in this one to see if it had any effect. It booted normally, but almost immediately showed a blue screen error and rebooted again. The BSoD flashed too quickly for me to see what the actual message was, but it happened twice in a row.

Is there a log in Windows somewhere that i can read to determine the cause?

Thanks again for your assistance.

Regards,

--- Gary
