NO signal error

[Hackster]

GPU: GeForce GTX 970 CPU: Intel(R) Core(TM) i5-4690K CPU @ 3.80GHz Memory: 16 GB RAM (15.94 GB RAM usable) Current resolution: 1920 x 1080, 144Hz Operating system: Microsoft Windows 10 Pro

this is the specs of my rig for past couple of day's my pc is crashing usually when I start  fortnight clash is like no signal and sometimes my pc is working and sometimes not, either way, I need to restart my pc manually I am using stock cpu cooler and it is over heating becoz of summer temps it is in the high 80s while gaming I am changing my cpu cooler pretty soon but everyone is telling me it's gpu fault but I am not sure there was one time only when I try gta 5 and I was getting 30 fps max after that my gpu is fine even I have done a stress test for about 20 mins with ad64 exterim for gpu only. my Gpu has only 2 month's warranty left. asus gpu app was showing min max same clock frequency .

Things i tried:- 1st all drivers are updated 

2nd. thermal past has been replaced

your cpu shouldn't be hitting 80c if the cooling system is working correctly. I'd suggest turning on the building AC so your room temp doesn't effect the cpu temp.

What I do not understand is that your CPU isn't going 100% and does not thermal throttle on AIDA test..

Okay but my pc is acting weird whenever i play fortnight it will crash saying no signal or it will give low fps 60 max or it will work fine sometimes

I know i am buying cpu cooler pretty soon but i can't understand why my pc is acting weird like low fps constant crash saying no signal pc was working on background and i completely format my pc too same issue but crashing are less now only low fps like 60-65 but i usually get 250-190
