I can go into the power menu but it won't tell me what the problem is.
If i hit F1 the thing will boot up and run normally.
What could be the problem?
It is running Windows XP Pro.
Could this be a problem with the power supply?

You can try restarting your laptop and then hitting F8 repeatedly and then choose LAST KNOWN GOOD CONFIGURATION.If this doesn't fix the issue then you will have to go for a recovery.This is the only way to fix the issue.

My Viao will bootup and then restart after a couple of minutes. This continues until I finally unplug the PC.

Hardware monitor error


Sounds like loose connection on your monitor card, if installed seperately, otherwise the wrong drivers installed.

Boot up in safe mode and uninstall the monitor drivers. and try and boot again.

Let me know if need further help.
