Resolved Question

Computer won't turn on

by annej96 / October 6, 2014 7:45 AM PDT

Any help or suggestions would be greatly appreciated: I have a desktop computer that was working fine the other night but this morning when I tried turning it on, nothing happened. I unplugged everything but the power chord and the monitor- still nothing. I took out the power chord, waited several seconds and then plugged it back in, and when I press the power button it came on for a second the turned off. There is a little green indicator light showing that the system is receiving power.

The computer is a Windows Vista Home and Premium OEMAct. The tower has a Compaq logo, the model number is CQ511OF. It is an older computer I'd guess maybe 7ish years old.

I'm hopeful it might be the power button, but I know it may also be the motherboard.

Thank you for your time

First guess, PSU failure. HP/Compaq and many other out of the box computers have very basic (pretty whimpy) power supplies, they do fail. If you are not tech savvy, take it to a shop and have it tested. PSU replacement is not a major job and a basic supply is not that expensive. If it is a supply, the whole job should take no more than 15 minutes.

I'd do the canned air and thermal paste before trying to troubleshoot.

I would try unplugging it for a longer period of time. While it's uplugged, try cleaning it up really well (canned air...make sure all dust is out). If nothing else works, you may have to bring it in to have it serviced. Here's hoping it's just the power button. If you haven't noticed any other problems with it at all, it's a possibility.
