I have an issue is my pc will randomly auto turn off without any error message (no blue screen) and after auto turn off i immediately check my graphic card power light is immediately off (because as i know normally if power cut off the graphic card light will still on for short period). After that i cannot turn on my pc after it auto turn off, but i leave my PC and wait for around 5 - 10 minutes until the graphic card light on only able to turn on my PC(without turn off the power switch). It is power supply issue?

I have check event viewer it only return error about system not turn off properly previously and kernel error 41

Solution
Please list the tier rating of your PSU. You can run a stress test that would indicate voltage efficiency under load.

Download HWMonitor and AIDA64 and put them side by side on your desktop.

Run stress tests and monitor temps and voltages in HWMonitor during testing.
If not sure how to analyze then take screen shots at 10 min mark and stop test if temps reach 8OC.
Upload the desktop pics to IMIGUR and obtain the BB url to link to your post here.

Thank, this is temperature on normal mode, idle i not monitoring because is randomly turn off, the stress test i will test and update status on tonight
FYI, the highest temperature i hit is 70C for processor in gaming mode
 
That's pretty conclusive LoyalTraitor. Your temperatures are not holding under load and approached the 100C mark on the FPU within 30 secs. The FPU is an integrated and most complex part of the processor. When stressed it will generate the most heat. Its good you stopped the test when you did.
Considering you have no Overclock then your thermals are way too high and the probable cause of your system shutting down.

You must evaluate your cooling system as its not doing its job or your TIM needs to be replaced.
List the Cooler please.

The GPU temperature is a little high but acceptable under load at Max 77C after 11mins.

Also assess the fans for inlet and exhaust within your Case.

Thank for reply, can i know what is the full form of "TIM"?is it mean thermal paste? I am using traditional fan cooling system (brand : Cooler Master), if not include graphic card and processor build in cooling fan, i only have one cooling fan on front position of my cpu. But this PC i already use for 3 year and this case only happen on nearly period. FYI, I am long time not using this PC to playing any game (normally is facebook, watching video and listen music). I try to open the casing to check the processor, graphic card, PSU cooling fan all are working properly(include the extra cooling fan at front position of CPU).

TIM stands for "Thermal Interface Material". You should replace with AS5 and at the same time consider the following.
Your single 120mm fan is inadequate to cool your system.

You have the option to install:
Front: 140mm fan x 1
Top: 120mm fan x 2
Rear: 120mm fan x 1
Bottom: 120mm fan x 1

I strongly recommend you improve your cooling capability by installing theses extra optional fans.
