HELP: PC Randomly Goes Into Black Screen

[killmykill]

So I got a brand new built PC, and I noticed that after using it that sometimes I just randomly get a black screen.I can't do anything when I get it, my only option is to shut down the PC and start again.
My PC Specs:
Motherboard: ASUSTeK COMPUTER INC. Z97-P (SOCKET 1150)
GPU: 8192MB ATI AMD Radeon R9 390 Series (ASUStek Computer Inc)
CPU: Intel Core i7 4790K @ 4.00GHz
OS: Windows 7 Home Premium 64-bit SP1

I had similar problems and a bios update solved them

First the Motherboard he linked has a BIOS version for the z97-p chipset of 2601, You only need to flash the bios for a Core i7-4790K if the BIOS version is below 0310. Considering the CPU he linked is compatible with all z97 chip-sets that is not the issue. -Source

Your problem is lying in the fact that you have a r9 390 which can pull max torture testing around 40-45 amps, so unless your 12v rail is a big, bad sob more then 55+amps dedicated 12v rail. your computer wont do anything.

700W 80+ PFC 12cm Silent

This is everything the store said about the PSU I have. Should I try to open it up and look for more info?

Okay, so I'm pretty sure this is the PSU that I'm using.

Taip, iš varlės. Čia kaip supratau tai problema tik su PSU yra,visa kita veikia puikiai,dar palauksiu atsakymų iš kitų pažiūrėsiu gal kažką naudingo pasakys. Jei ne tai į varlę eit reiks ir sakyt jiem kad tvarkytų.

Tomorrow I am going to the seller to talk about this problem,but I'm pretty sure its the PSU because when i turned off my from LED fan the problem was'nt occurring as often as before. I also removed some unnesessary USB devices like controlers that I was'nt using at the time.

yes he most likely solved his problem by changing the PSU.
