I wonder if someone can help me with a pc problem. I have AVG antivirus and also Zonelabs on my pc. But everytime I try to login to MSN messenger, the pc just shuts down and I have have to have several login attempts before I can finally get it running again. I tried uninstalling the MSN windows messenger and installing it again but no luck still. It seems that the hard drive makes a lot of noise and when MSN messenger tries to open, it will logout the pc within minutes. I've run the virus check and no known viruses have been found. I ran spyware as well. Anyone any ideas or help.. I really am stuck.
