Open System in Control Panel.

On the Advanced tab, under Startup and Recovery, click Settings.

Under System Failure, select the check boxes that correspond to the actions you want Windows to perform if a Stop error occurs:

Write an event to the system log specifies that event information will be recorded in the system log.

Send an administrative alert specifies that your system administrator will be notified.

Automatically reboot specifies that Windows will automatically restart your computer.

Select 'write an event', untick the reboot option.

Now you will get an entry in Event Viewer which should indicate the source of the problem.

It would appear that your shut-downs are due to over-heating. You may need to open up your case and make sure that the inside and especially all the fans, are clean and clear of dust and fluff etc. Also make sure that the computer is in a clear air flow all around.

to stop the problem my pc currently has no sides on it at all! (its pretty much the bare case!!) looking at the temp readings i assume its the temp sensor 2 thats causing the problem,does anyone know where this is?

have a look inside and see that all fans are actually rotating. Some fans are only about £6 and can fail.

Check all fans running.

with PC shut down
Scrape the crud off the fan blades
Clear all fluff from grills
clear muck from fins on heat sink
may even be worth removing PU and hetsink and cleaning off old thermal paste and renewing paste.

A computer runs hotter with the sides off! A through-flow of air normally in at the front, out at the back is best, hence case fans which normally do this job. I would advise you to re-fit the sides soonest.
