Computer boots off 2-3 minutes after boot.

Hello, yesterday night I turned off my computer by the PSU switch on the computer and I woke up today, turned it on and it was working fine for a while then it shut off, and then it kept happening. I looked up things about and I thought my CPU was getting to hot, so like my thermal paste was not working, I applied new compound and it boots for about 2-3 minutes, and just shuts off, no "Windows is shutting off" just turns off, my specs are

GPU- Evga GTX 970 ssc (BRAND NEW)
CPU- i7 4790
MOBO- Gigabyte z97x-SLI
PSU- Coolmax ZX-700 700W
I don't know if I don't have enough air flow to my cpu but I have an H105 AIO cooler by Corsair.


Thank you guys!

check your temps in bios and report back anything odd.

if you got your 970 brand new then you might have fried your coolmax PSU as it is not know as a very good power supply. try swapping it out if you have an extra one, or even leave it on for a few min to let the cap get charged fully, buy i bet anything you 970 is and the rest of the pc pulled too much power and it is not maintaining a constant amperage any more fluctuating and causing a crash.
