New Build but monitors go black and pc keeps running

[Zyph]

Hi ,

 

I really hope you guys can help me out since I don't know what the issue can be for this problem.

 

I recently bought myself a setup but have some issues with it.

 

AMD Ryzen 2700X

X470 Prime Pro

16GB DDR4 Trident G 3200Mhz ( is on the QVL list )

MSI Rx480 ( 4GB ) -------> coming from my old build

 

 

Now mostly since gaming , I noticed that sometimes ( once or 2 times a week , my monitors don't get any signal anymore and so I have to reboot my pc to get signal again )

 

What I already have done but those crashes still remain: 

 

Reinstall windows 10 

Driver reinstall ( DDU )

BIOS update 

memtest ( No errors )

Used 1 monitor on different cable connections 

Bought new PSU ( Since I had a old PSU that will still strong enough ( works on another build so no issues there )

 

What I found out now , it that when I use Furmark for benchmarking. It instant crashes ( Black screen but pc stays on ) when starting the benchmark. 

Other benchmarks 3D mark works well. no crash.

 

CPU temp max 50°C stressed

GPU Temp max 60°C stressed

 

So will it be my gpu or any other guesses ?

 

thx in advance.

 

sorry for my english since its not my main language.

Do your peripherals lose responsiveness as well?

Very often my USB mouse or Keyboard does not get recognized yea. So I have to plug them in again
