Black Screen in sertain games

[b.melchiorsen]

Don't know where to post this so i will try it out here.
i have a really strange problem my computer is randomly black screening with in minutes when i play CS:GO and WoW, i can play PUBG and LoL for hours with no problems.
the system is not overheating GPU is on 50C and CPU is at 60C Running Prime 95 and furmark at the same time for about 1 hour without crash
there is failcodes i can use to anything in the windows log. so yeah i don't really know what to do.

i have tryed the following
-reseating the GPU
-reseating the CPU
-reseating the GPU power cables
-changing the sata ports for the ssd and harddrive
-memtest86 (no failures)
- changing CPU
- clean install of windows 10 (3 times)

Here are my specs

Motherboard: Asus Rampage III Extreme
CPU: i7 920 / 930 (black screens with both)
RAM: 16 GB mixed ram, just running stock bios settings
GPU: EVGA 780 hydro copper
SSD: Samsung 840 EVO 250gb
HDD: Seagame 1 TB

You say you have 16GB of mixed RAM. If that’s the case then that may be your issue. Black screens are often a symptom of RAM issues. Try using 8GB of RAM from the same kit and see if the games still black screen.

Yes I agree with Jwpanz it may be your ram try resetting them or try each stick to check if it works

The wierd thing is that it have worked with all these rams, might be the power supply. but the power supply have also worked with a system almost identical the only diffrence was the graphic card, but its a shitty PSU with no name on it 😀
- but i have a PSU comming from RMA soon so i will try that one in the system when it arrives
i just think its really wierd that the system crashes when playing games that not that demanding, and not when running prime95 and furmark at the same time :S
-update have tryed the system with one kit ram problem is still there
