Monitor turns itself off randomly

[stampsUser]

Hi Guys

I am running Windows XP Pro and the system has been fine for the past six month. However, starting last week, the monitor turns itself off at random times. After login, at times it turns off at startup, and other times it turns off after staying on for couple of hours. I have tried the following:

1. Made sure the Power Options are set to Never turn monitor off.
2. Checked settings on monitor.
3. Ran Virus Scan and Spyware.

Any ideas what could be causing this?

Could it be an overheating issue ?

Open up your PC and get rid of dust on your fans and heatsinks. Try running the PC with the side panel taken off.

Take a look at your event logs (EVENTVWR). Any nasty red error messages ?
