unexpected shutdown

[Guest]

my computer shuts itself down unexpectedly either if theres too many programs
running, or when i running a java game. the computer lasts about 20 minutes
before turning off, withought re-starting, and then needs to be switched back
on. also, directly after the computer shuts down, u cannot imediatly turn it
back on, it would turn on,and turn of imidiatly, and i'd need to wait about
30secs-1min before it could be started again.

In order to find a more specific cause for this problem, please turn off the
Automatically restart option - here's how to do it:

Go to:
Start...Control Panel...System...Advanced tab...Startup and Recovery
Settings Button

Uncheck the box that says "Automatically restart", then click on OK to save
the setting.

Reboot your system for the changes to take effect.


The next time that your system tries to spontaneously restart, you'll be
shown a Blue Screen (fondly called the Blue Screen of Death - BSOD).

Please write down all the numbers and letters after the word STOP in the
stop error message - this will help in troubleshooting the problem.

Also, occasionally a filename will be listed in the error message - please
write down the file name or note that there isn't one listed. This filename
can narrow down the search for the problem with your system.

This sounds more like a hardware problem. Overheating would be
the first thing I'd check. Open the case with the system
running and make sure that all fans are running properly. There
should be at least two, one on the processor, the other on the
power supply. Turn off the system and carefully blow out any
dust and dirt with a can of compressed air. Be careful not to
make contact with any of the internal components.

See if your system has a utility included that displays system
temperatures. If not, go to this web site and download Everest
Home Edtion. Run the program and look under Computer -> Sensor
for the relevant info. Most systems at idle will display temps
around 40°C or less. Anything above 60 is on the high side. If
your system's running in the 70's, you're flirting with
disaster.

FYI, overclocking this system would add to any overheating
problems that already exist.

If it's not overheating then you might want to take a look at
the power supply and the memory. Make sure your power supply is
strong enough to run your system. Take a look here for a
utility which gives you a rough estimate of what size power
supply you should be running:

Run the following utility to test your memory:
