CPU overheating seems the likely culprit. I had the *exact* same thing happen to me a couple months ago.
I removed the heatsink and saw the existing thermal paste had all dried up and solidified flat stone-hard. Just smeared some more and the problem went away immediately after.
He did mention that he check the temps for the cpu so I dont think that could be the reason.

My computer has been cutting off with no warning at random intervals. It seems to happen most when I am doing something intensive, but has also happened when all the only thing running is Chrome and I am actually away from the computer.
I don't get a blue screen, or any errors. It just powers off, then turns back on.
When it boots back up I get the Windows shut down unexpectedly prompt, but other then that no errors.
Sometimes it cuts off again while booting up. This can happen several times before it gets through the boot successfully.
I have monitored CPU and GPU temps with a log, and there are no spikes or other anomalies.
Some days this will happen very frequently, other days go by without an incident.
I am pretty much stumped so I need help. It might be the PSU, but I have no way to know for sure.
Here are my system specs:
Motherboard: ASUS P8Z68-V LE
CPU: i5-2500K Sandy Bridge 3.3GHz
Video Card: GeForce GTX 560 Ti
HDD: SAMSUNG Spinpoint F3 ST1000DM005
PSU: TX650 V2 650W ATX12V v2.31
OS: Windows 7 64bit
Thank you in advance for your help.
Your best bet is to buy a new PSU and try it out. If the issue still occurs just return it so you can get your money back. However, I really think it could be the PSU and if not, than the GPU.
