RE: No response after running for several hours -- PCTECH

First, check the Event Viewer to see if anything has been logged.  If
there's nothing of interest there...

1. It may not be overheating.  It could be some form of power
management.  Try pressing the power button instead & see if the machine
reboots or un-suspends.
2. I've seen power management schemes where the system will suspend &
won't un-suspend.  So failing that, in the BIOS, disable all forms of
power management. 
3. If it's still locking up, there's a power problem, software problem,
or cooling problem.  
3a. To test the cooling/overheating theory, use a benchmark tool or
something that stresses the CPU like SETI@home or Folding@home.  That'll
max the CPU & generate heat.  If it runs for >1 hour and doesn't lock
up, it's quite likely not a heat issue.
3b. Software is harder to diagnose but try running in Safe Mode and see
of the lockup occurs there.
3c. Power can be even trickier.  Best to describe the system (# of
drives, amount of RAM, # and type of expansion cards, size & age of
power supply) and we can make an educated guess as to whether or not the
PSU is failing.

Subject: [PCTECH] No response after running for several hours

I have a home PC that seems to just check out after a while.  If the
system is left alone long enough, when I come back, it won't respond.
The monitor has gone into sleep mode and moving the mouse or pressing a
key doesn't bring it back.  I changed out video cards and no difference.
I'm wondering if maybe the system is overheating but I don't know how to
check that out.  The system is an AMD 1700 CPU on an ECS K7S53 system
board.  Can anyone help with how to determine if the system is
overheating?  Any other suggestions would be welcome also.

Rick
