Machine shuts down

    I'm working on an HP 6005. It's a slimline desktop running W7 Pro. It shuts down as if someone pulled the plug.

    The first time it shut down was about 20 minutes after it booted. After restarting, it shut down just a few minutes after rebooting. The sequence repeated. With each sequential reboot, it took less time to shut down.

    So, I'm thinking it's a heat problem.

    But ... I can leave it at the BIOS screen for at least an hour and it won't shut down.

    I pulled one, of two, RAM modules and got it to run for over an hour until I shut it down. I put that RAM module back and pulled the other RAM module. It ran for over an hour until I shut it down. Thought re-seating the RAM fixed the problem. Not so, it continues to shut down when Windows is running.

    Right now, I've been running MEMTEST for 2 hrs, 30 minutes (3 passes so far) and it's still going.

    I thought it may be the PSU, but since it seems to run nicely when not booted into Windows, I think it may be a Windows issue. (A thought just came to me to try it in Safe Mode).

    Unfortunately, I can't swap out the PSU because I don't have a spare for this proprietary unit.

    Any thoughts?

    Psu is the most likely Tony as those things are always underpowered. Here is what I would do is open it up blow out the innards with a "can of air" (especially the hsf) and then retry. If all else fails you can try a normal psu to see if that is it obviously you won't get the case shut but you can find a way to work with it.

    Thanks Rich. Yes, the PSU is suspect. The machine is very clean. Can't try a normal PSU because the connectors are different.

    Ho 6005's are not underpowered for what they are - they are corporate models and in the corporate environment they typically function as needed. We have literally thousands of the 8300 series here in our corporate offices but they are the newer ones with Ivy Bridge 3570's. They rarely ever fail.

    However over time yes, they fail like any other power supply will, and it does sound like it may be a power supply issue on your case.

    After I ran that MEMTEST, it seems to be fairly stable when booted to Windows. Don't know what's going on here.
