Unsure... Seems like hardware but may be OS

Hello and thank you in advance...

We have a desktop HP (coming up on 3 years old). It had been off for a few weeks. Today when we attempted to boot it, it started... gets as far as allowing a login sometimes, others it does not... then it acts as if it powers down... video feed to monitor goes off, power to USB speakers stops and the keyboard locks (no lights work, no beeps on holding ESC). Nothing works, including pressing and holding the power button to do an actual power off. You physically have to unplug the base to get it to shut off. And even then, the power light stays on for 5-10 seconds after unplugging before it finally goes out. This happens in ALL modes... Safe, safe with networking... all of them.

Personally, I am thinking it may be a power supply problem... But wanted a second opinion.

Thanks again!
Brian

welcome to geekstogo, a simple way to see if it is or is the os is to try a linux live CD like knoppex, since if that works with everything ticking then one has narrowed it down to the harddrive or the window installation, while running knoppix one could also see if it mounts the windows system(just meaning shows up the windows harddrive) which would probably rule out the harddrive too, pointing to the os

anyway, because the harddrive is untouched by the test since the live CD loads only to the ram, you do not effect your system one bit by testing with linux, thanks

Hi bbrown103, welcome to Geeks to Go!

I also would suspect a power supply problem, I have heard of problems occurring with the power when the computer has been off for a while. ("I've been on holiday, and now I'm back my computer won't work...)

If it's not the power supply, fleamailman's option may also work, but if you want to avoid a 700MB download (on a working computer, no less) then you can try Puppy Linux for only about 80MB, it should be able to test the same idea nicely.

Let us know how you go. :)

Thanks again. Turns out it was the power supply and the fan... Replaced them both and now all is well! Thanks again for verifying my thinking!
