PC wont reboot

HI

When im trying to reboot my machine it fails. It shut downs and the monitor turns off. I expect the monitor to turn on after a few seconds but nothing happens. The coolers just keep running but nothing happens. I will have to turn off the power and keep it that way for 5 minutes before i can start it up again. Just updated my BIOS and re installed XP and neither of these helped.

Anyone have an idea or experienced the same ?

Does it shutdown during use then need a rest before restarting? If so it is overheating. Check the CPU heatsink for dust clog, and ensure the fans are spinning freely.

It works fine for several hours(even days), its only when i press restart (after some installation) that it does it.

After an installation (or anything else) you should not press the reset button, you should click Start, Shutdown, Restart. Pressing the reset button can damage files and may cause problems restarting.

Thanks to all so far.
I forgot to mention that my reset button is disabled. It happens when i press Start -> Shutdown -> Restart. Will soon test some of the suggestions.
If its restart from the shutdown menu (as you say), then have a look for the sleep level as mentioned above (look in the BIOS). If it's at S3 or similar now, try lowering it to S1, this will make it easier for your hardware to comply with the restart command Windows is giving out.

I had another power supply and it worked much better. It was already set to S1 but now i understand what means. Thanks to all for feedback.
