Computer crashes while playing games

[LGDX_lepou]

Hello! I bought this computer a year ago and last week it was the first time that my computer crashed while playing a game. At first it would do it once per day but now it has become worse. Up to 5-6 times. Usually happens when I play high-demanding games including COD:AW, DayZ and League Of Legends (not really demanding but that's the first game it crashed on.). I looked up in the dump folder in "C:\Windows" to see if there was any crash report and there's none. The way it happens is that while playing normally, the game starts to drop FPS and after about 1-2 minutes the screen goes black and the computer makes a weird sound and it shut itself down, although it restarts immediately after.

Specs:

Operating System -> Windows 8.1 64-bit
CPU -> Intel Core i5 4440 @ 3.10GHz
RAM -> 8.00GB Single-Channel DDR3 @ 798MHz
Motherboard -> ASUSTeK COMPUTER INC. K30AD_M31AD_M51AD (SOCKET 1150)
Storage -> 931GB Western Digital WDC WD10EZEX-22RKKA0 (SATA)
1863GB Seagate ST2000DM 001-9YN164 USB Device (USB (SATA))
Graphics -> 3071MB NVIDIA GeForce GTX 760 (192-bit)
PSU -> 500 Watts

All of my drivers (so far) are updated. I've never experimented those crashed until last week.

You should try running program the check temperature and voltage. hwmonitor works very well. http://www.cpuid.com/softwares/hwmonitor.html

When you say "crash".. It just die.. and reboot? or give you a crash screen or something?
If it just resets, and if its not temps.. I would look at PSU
What brand your PSU?

Cheers

I found the problem. Last time I opened the computer I cleaned all the fans except the GPU one which ultimately led to it having issues. It would go up to 100 degrees. After I cleaned it, everything got back to normal.
