The problem is that the computer freeze now and then when I'm usin voicechat and/or videochat in Skype and MSN.
Sometimes the computer freeze after only a few minutes, and sometimes I can chat for hours before it happen.
If I remove the graphics card, and run only with the built-in, then the computer doesn't freeze at all.
It's very rare, but still happends, but not so often.
So I wonder what the problem is?
I think it may depend on the power supply or the mother card.
Maybe the power supply is too weak, I have only 300W.
Can anybody help me?
