What can cause a computer to shut down without warning?
I have run memstest86 but the RAM is all OK. Also run a total virus scan
using McAfee (which has always been installed and running) but no virus was
found. No new hardware has been added recently. And I have not noticed
that I was doing anything that could be a common cause of the shutdowns -
they seem to be random and sometimes allow me to work all day and other
times it shuts down after 5 minutes.
I have noticed that I regularly get a disabled desktop waring saying there
was an error 'object doesn't support this action' in line 65 of desktop.htt
but it is the same desktop I have always used and it loads fine in
FrontPage.
Any ideas what to look for next?
If there are NO event log entries related to the shutdown, if it just
SHUTS OFF, then you have one of several problem, check the following:
0) Run a AV/Malware scan using MBAM, download it from:

1) PSU Fan(s) - Are the actually spinning and clean?
2) Video Card fan/capacitors - check to make sure the fan is spinning
and clear of dust, check the CAP's to make sure they have not popped.
3) Case Fans - If your case is one of the smaller ones, or has a lot of
components, case fans can fail causing your computer to overheat.
4) CPU Fan/Heatsink - make sure that the heat sink is clean and that the
fan is spinning. If youv'e checked the other things above, it's been
seen that improperly applied CPU heat sink paste can deteriorate after a
number of years and provide insufficient cooling. You should check this
if you are comfortable with working on the CPU and inside your case -
reapplying HSP should be done following the manufactures EXACT
instructions for your type of CPU.
5) Bad power supply - in many cases, when none of the above are the
reason, changing a PSU with a new one can resolve the problem. A cheap
PSU can be purchased for less than $50, as a test, or a better quality
one can be purchased for under $89.
