PC reboots a few seconds into skype videocall

[spirosbomberkl]

I have a pc which had windows xp. I have been using skype a lot. A few days ago a very weird problem appeared. When I start a videocall the pc reboots 10-30 seconds after I start it. If I start a call without video, everything happens normally. I reinstalled skype and windows and the problem remained. I heard that the latest version of skype had problems with windows xp and I wanted to upgrade to windows 7 for a while anyway, so I installed windows 7 and the problem remained. I have tryed 3 different web cameras, no luck.
I tryed to use my web camera at another computer, and everything works fine. Any help?

If you haven't already, install Service Pack 1 and all windows updates. It sounds like it's crashing due to a graphics problem and the crash causes the PC to restart.
