PC Randomly Shuts Down...

From your description it sounds like a thermal problem, either thermal shutdown due to over heating or a badly fitting component that on expansion is loosing connection.

First off I would ensure that all components are seated correctly.
Make sure there is no dirt or dust causing a bad connection.

Now as a test I would try running it without the case sides on and see if it makes any difference. If it does then its definitely a thermal problem and you coould do with some more case fans for extraction..

Please post back with your results of these steps and we'll see what else we can suggest.

Maybe your right, I'm thinking about a new power supply but when you mentioned thermal stuff it come to mind,

When I got this case and fully mounted the mainboard to the case tray then inserted it, the expantion slots was on a wonk so I was unable to insert the PCI-E slot graphics card I bought, but to solve this I had to put the MB on a slant and screw all of the screws in that was possible.. (but slotted in fine after that)..

Another thing was with this Heatsink and CPU fan I bought, because of my ASUS motherboard I had to attempt to use the brackets supplied but obviously they was the incorrect type so I had no other option but to force them on....seemed fine to me because the CPU was securly on..but the CPU heatsink/fan is on abit of a slant, and touching the plastic...

Was hoping someone would have a similar problem as me, so I could solve it.. I can't think what else to do, appart from to send the powersupply back to overclockers and receive a new one...

Ill keep you updated, if I get some old brackets for the CPU heatsink. Please if anyone else can add a reply on a suggestion possible please post here..

Thanks a lot for your suggestions and help, will look forward to hearing from you again

But again, it's weird because if I leave the system for 15 minutes, too let it cool down or whatever it boots up fine for like another 10-50mins..

Really confusing and fustrating because I've got college work to be getting on with >.<

Thanks, Liam.

Get your heatsink on there proper with the right retention plate and not too much pressure when locking it down...its very important to use the right plate..also when you put paste did you remember to coat both the cpu and heatsink...once you slap those 2 together they must not be lifted off each other or else you have to recoat both all over again...make sure the heat from that vid card is exhausted out of case somehow...extra heat in case is no good....goood luck

Ps..try a different power cord just for the heck of it..may be a defective cord with high resistance

Thanks a lot, you just made me relise about the CPU heatsink so I did some research and come across a guide on how to install the certain CPU heatsink to my ASUS mainboard, and guess what! Instead of putting the brackets on downwards properly, I put them facing upwards, so hopefully this may have fixed the problem. Unluckely I had to remove the heatsink so ill have to buy some more thermal paste again soon.. Before I just put it on the silver part of my CPU and not on both heatsink+CPU, ill keep you informed.

Oh and I replaced the power cord, and I have one side of the case open already..

I imagine it would have been because the heatsink wasn't installed properly but see what happens. What might help is a motherboard monitor that can sound an alarm when your PC gets too hot. The best one I know of can be found at http://mbm.livewiredev.com/

Thanks, I've downloaded it, seems a good program to have - and the computer hasn't yet powered off, so things are looking good

Bleh, just when I was doing good, the computer died once again :/. Can anyone else suggest anything? Please, thanks.
