PC randomly shutting down?

[YOMAN282]

Hello,

I've been getting this problem for few weeks now, my PC just shuts down doing random stuff gaming or surfing... But it's not common, it's like twice a week maybe, 3 times max. Just a few minutes ago it shut down while I was surfing, no shutting down screen or anything, just shut down and starts itself again. I just recently upgraded mobo and cpu, before the upgrade it wasn't happening. Temps are: GPU - idle: 37-40(now it's hot here so it idles at 39-40C but when it's colder it drops to 37-38C) and when I'm gaming it's around 60C, CPU is idling around 35-39, it can idle even lower as I sad it's so hot here right now and when gaming around 50C. PSU is XFX Core Edition 550w and GPU is VTX3D HD 6770, it's around 1.5, 2 years old, maybe it's dying?

What cpu, mobo, OC?

Take a look in windows/administrative tools/event viewer. Look for critical errors, they are usually the cause of shutdowns if temps are good. Anything under cpu-70 and gpu-80 is acceptable range. Also, is the pc water cooled or air cooled.

No overclock, i5 3470, B75MA-E33, air cooled

Event viewer?

 

[YOMAN282]

There are no any events that happened at that time, 20 minutes earlier was application error and a bit later Kernel power critical error ID 41

ID 41 is where for what ever reason, the cpu is short on voltage. That's odd for an XFX and locked Intel as vcore voltages should be auto.

Huh weird. It happened today but before that, last shutdown was 2 weeks ago as i remember while i was playing csgo. I checked the time of the error and its almost 40 minutes later than it actually happened?
