PC crashing intermitently

I have a 6 month old 'Palicomp' PC. It has Intel Core i7 860 cpu @ 2.80 ghz, 4Gb Ram, Ati Radeon 5800 HD 1GB, Windows 7 Home Premium 64 Bit.
About a month ago It started to shut down and re-start itself. It may go days without doing this then do it 3 times in one day, I'm baffled.I've used System Restore to a date before the trouble started but no luck. I also regularly scan for viruses and run CCleaner. Before I start talking to Palicomp on their expensive helpline I thought I'd post this for any sugestions...and please dont suggest I shouldn't have bought a Palicomp in the first place....I did get the recomendation from PCA

Often this type of behaviour can result from CPU overheat problems. The cause of the overheat may be poor airflow as a result of dirt/dust, a failing fan or a bad thermal connection between the heatsink and CPU. The CPU shuts down if beyond its normal max temp to prevent damage.

Probably the first place to start is to have a look at temperatures & fan speeds using something like Everest Home (its free) click here.

You could also have a look around inside to see if everything is clean. Make certain you turn off and disconnect first.

Windows Explorer - right click 'My Computer' - select 'Properties'
on System properties -select 'Advanced' - select on 'Start Up and Recovery' 'Settings'
under 'System Failure' untick 'Automatically restart' click OK

may be simple thing triggering the restart ;)

If it's only 6 mths old, I would think dust/clogging is unlikely. I'd just return it for them to sort out under warranty.

control panel >> system and security >> system >> advanced system settings >> startup and recovery settings >> untick 'auto restart' box
you can then see whatever error message caused the shutdown, post it back here.

You can also check the Event Viewer to see if it registered anything

I had this exact problem and in the end I had to replace the PSU; after this it was ok.
