[Ham-Computers] Question on Win 95..has me stumped

[Brian K. Gaskamp]

I recently got a weather station installed on a old computer running Win 95
and I leave it running pretty much all the time, when I'm not around the
computer I leave the monitor off and after leaving the computer unattended
say overnight or during the day and I turn the monitor back on the screen
saver is on BUT the machine is froze...

I reboot it and everything runs fine.

Whats causing that...Its probably simple and I'm overlooking something.
