Yesterday I've got a problem on my PC that, my PC always restarting anymore and more and more. What's the point of problems on my PC?

Take the GT630 out. Does it work then?

The Corsair VS450 is not a very good psu.

That's working but only about 6 hours, then it restarting again.

Have you dusted you pc recently? If no, dust it first, including the power supply.

Never. Because I just bought the processor and ram as brand new with box. When I put it on motherboard, then "restarting" was happened
