Hopefully someone can help me. I started working on my computer this morning as usual. Opened up my programmes ( Internet Explorer, Outlook Email ) and started to reply to my emails. I then opened up MS Office Word to print labels and my screen went blank, yet the power button stayed lit. I pressed the power button off, then back on again and my screen came on for two or three seconds and went off again. It did this several times before I decided to reboot to see if that made any difference but no, still did the same thing. Then after a few minutes, I turned it off/on again and this time it stayed on - great I thought. But no, it started doing it all again after a few minutes. I've now managed to get it to stay on again ( hence my typing this ! ). I'm running a full virus scan and a spyware scan in case that is the problem. I don't think heat is a problem as my monitor and computer are fairly well aired, with a fan blowing at them most of the time. I have an HP Pavillion computer with Flatscreen monitor F1703 which I've been using since Christmas, so far with no problems. Would it be possible that this problem is virus related, or maybe it is overheating - although the computer is running as silent as it always does. Any suggestions would be great. Thanks Mark.
