My newly build PC's keeps shutting down and restarting. I can use my PC for like
5-10 minutes, then it shuts down. I'm 100% sure its not the CPU overheating because I did not overclock it.
I think its the power supply. because when i change the socket for power supply after it shuts down , it starts and works for like 5 mins then shuts down. However problem is consistent, i don't know when its gonna shut down. Windows 8 shows no crash report.
Do you guys have fix for this problem ?

Specs:
-Intel i5 3570k
-Evga Geforce 650ti boost 2gb
-mobo t z77b
- Power supply corsair CX430
- 8GB ram
- Running windows 8

When you say shutdown, do you mean that the machine just cuts out, bluescreen or does it suddenly come up saying windows is shutting down

Also it could be an overheating CPU if the CPU cooler isn't installed properly (which i hear is quite easy to do with the intel stock heatsink, assuming that is the one you are using). Download HWMonitor for CPUID and it'll tell you the temps and voltages of all lot of your components.

What are you doing when it shuts down? Does it matter (ie if you leave it idle at the desktop does it still do it or if you stress it out it will happen after a shorter period of time)? Try running some stress tests (OCCT or prime95 for the CPU and unigine heaven/valley for the GPU) with HWMonitor open and look at temps etc and whether the shutdown happens quicker.

Finally, and this one is only possible if a troll has used your computer, check your startup folder for a batch file that includes a line saying something like:
shutdown /s /f 300

Hope this helps you start to resolve the problem, and report back any findings.

Machine just cuts off electricity, no power, jst BAM. I wil try out the heatsink, but what about the thermal paste thing? is it okay? Also the mobo has temp meter and it says around 40.
No trolls I built it like 5 days ago.

What do you mean by "I will try out the heatsink?"
As for thermal paste, the stock intel one comes with it pre applied, which will be good to go for first installation. If you have used the heatsink before and are reusing it, you'll need to clean the heatsink itself and the CPU of the old paste and apply new stuff.

I assume the mobo says it is around 40, that you are in the bios and reading the CPU temperature from there. In which case that is the idle temperature, and the load temperature is what would be causing you trouble.

Out of interest does it still cutout when you leave it at the bios?
