i bought my PC 1 years ago and last month my PC suddenly turn off (until today),
when i turn it on all fans on, no beep, blank monitor but my PC often went turn on and off for a brief moment about 1 or 2 sec.

my PC spec
CPU intel G2010
Motherboard Asrock B75M-GL r2.0
RAM Kingston value 2 GB PC 12800 (2 stick)
VGA Sapphire HD 6570 1GB HM
PSU FSP hexa 400

the component i already checked
1. PSU - try it on other PC its run well
2. RAM - just back from RMA 2 days ago
3. Motherboard - checked on distro and its fine so i can't get RMA.

the test i already run
1. put the motherboard on its box and disconnect all component except CPU i got 3 short beeps (i check at AMI BIOS beeps code it turn out normal) i make sure the 4 pin and 24 pin already connect
2. just try 1 stick RAM on socket A then socket B (i do it for both RAM) not work
3. try put both RAM on the socket not work to

i already read this http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems and check it all but still no.
and i already check my CPU and RAM seated correctly.

Dude if you think that your cpu is faulty then there are very little chances for that but does your cpu or psu gpu gets really hot then tell me cus it can be a reason and clean everything of your pc and try your cpu in any other pc if you can manage
