Hi Peter,
The problem can be heat related, or they could be a part of a system
failure. Go to the Control
Panel/System/Advanced tab, click on startup and recovery settings. Uncheck
the line to automatically restart in the event of system failure. This
should cause the system to produce an error message (blue screen) that can
be researched the next time it occurs.
If no error message occurs, then it can be an overheating problem. Random
reboots are often a sign of over-heating. Things you can do:
1) Open the case and make sure all fans are operating, especially the cpu
fan. While you're in there, get a can of compressed air and blow out the
dust bunnies.
2) Make sure the drive tower is well ventilated and not stuck in some
department store computer desk pc cabinet with only a little vent hole in
the back.
3) Visit a local pc shop and have them add an intake or exhaust fan. This is
not something you should do on your own unless you are familiar with the air
circulation pattern inside your machine. Adding a fan can be
counterproductive if not done correctly.
