Windows 7: Computer does random restarts after putting in a 350 watt PSU

The UPS is a good suggestion as well. ThermalTake and CoolerMaster are good brands for PSU as well. Was the PSU branded as such or just a case PSU. a lot of times, the case PSU's that are included are pretty cheap even if in a good brand case.... Not sure if you need more than 350W or not...

Did they run any types of programs during that 24hours? or was it just sitting? I would want to test it under full or close to full load for a bit....

Thanks for the response.

I honestly don't know if it was "branded" or "case" - I asked the tech who worked on it, and he removed the cover and looked, so guessing it was branded.

They did not run any programs, I'm very sure.

However, when I had the thing at home, I had several programs running concurrently, including Firefox with 10+ tabs open, multiples of which were auto-updating web pages, or pages with Flash or video content, plus I was using a USB drive, and doing an antivirus scan of the entire unit (because of the off chance it was a virus causing the restarts), and nothing bad happened - yet four restarts happened when the computer was just sitting at the login screen, with nothing running other than the normal background tasks and processes.

So I've subjected it to heavy use (about as heavy as it's likely to see in normal day to day use from me) and it held up, and I had it restart four times under no use whatsoever, never lasting more than about 3-4 hours without a restart.

So at this point I'm fairly comfortable it was something in the power source at my house (hopefully just the cord), but only letting (say) 72 hours pass with no issues is going to leave me 99% comfortable.

Near-final update, I hope.

The repair shop had the computer plugged in and logged into my account for about 30 hours, and other than it going to sleep on occasion - they'd wake it when that happened - it ran without restart or incident.

I brought it home yesterday afternoon, plugged it in with a different power cord, and it's been running for 13 hours now without restart or incident. I used it for about five hours last night - nothing deliberately challenging, but a Firefox session with 10-ish tabs open at once, Freecell, Excel. Pretty much an approximation of typical use. And I didn't restart it before bed like I usually do, and this morning, it was still logged in as I'd left it, with nothing "funny" in the event viewer.

If I have a couple more good days with this, I'll mark it solved.
