Hi everybody,

Starting recently I'm experiencing Vista lock ups after some period of activity. Both keyboard and mouse stop responding and I have to re-boot.

I switched to Microsoft Essentials antivirus over AVG and it found and removed few viruses (why they were undetected by AVG?)

Anyway, does anyone else experience the same problem and what can I do to troubleshoot?

Thanks in advance.

One more thing - after each such re-boot all my IE sites lose their settings and I have to type my passwords again.
