[jacobkindy]

My pc keeps crashing and im not sure what is wrong with it. I've only had it crash while playing fortnite. The Specs are :: gtx 970, i5-7600k, 8gb ram at 3000mhz liquid cooling and two drives. Please can someone help?

1| List your specs like so:
CPU+CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

2| Can you elaborate what you mean by crash? Does it reboot?

3| Are you on the latest BIOS update for your motherboard?

4| Can you verify that the issue is isolated to Fortnite alone?

CPU+CPU cooler: i7-7600k corsair liquid cooling
Motherboard: ASUSTeK COMPUTER INC. Z170I PRO GAMING (LGA1151)
Ram: Ballistix Tactical 8GB DDR4-3000
SSD/HDD: Drive (c) im not sure but it has 119gb storage my (d) drive is a samsung 850 evo 550gb
GPU: NVIDIA GeForce GTX 970 (Gigabyte)
PSU: im not sure ill check later but i think its the SF Series™ SF450 — 450 Watt 80 PLUS® Gold Certified High Performance SFX PSU
Chassis: Cooler Master Elite 130 Mini ITX Case
OS:windows 10 pro
I also have some things overclocked but even de-clocking them wouldn't help

2| By crash I mean the screen goes black and my lights on my keyboard stop in their tracks. Everytime this happens I have to press the restart button on my case.

3| I am not sure if you could tell me what the latest one is if so i could go into my bios and find it out

4| Can you verify that the issue is isolated to Fortnite alone? I'm pretty sure, I have tried video editing and photo editing and it didnt crash but that is the only game I have played. I have re-installed fortnite a number of times and not once did it stop the problem.

Try a more powerful power supply. My recommendation is 500w minimum.

Is their anything else I could do? I could try swapping my parts out from my pc with my brothers pc to see what it is?
