Here's an annoying problem that I've been having lately. My computer
has been freezing at random intervals. The strange thing is that
nothing is listed about it in the Event Viewer when I check it after a
reboot.

I updated the drivers for my video card; I ran my virus scan; I ran
CCleaner; I ran HIJACKTHIS and submitted the log file to
http://www.hijackthis.de, and I have found absolutely nothing.

It usually seems to happen more when the screen saver becomes active,
but yet it's still an intermittent occurrence otherwise.

Does anybody out there have any thoughts on this matter?

Thanks in advance.
