Pc crashing with black screen

PC SPECS 
motherboard: ASROCK A320M-DVS
PSU: Riototo builders edition 500W
GPU: GTX 1060 6GB
CPU: Ryzen 7 3700X 8-Core-Processor
Ram: Corsair Vengeance rgb PRO 8x2gb 3200MHz

So basically I started to get into stalker and when I played mod packs my pc started to crash with a black screen (no signal (and no blue screen etc)) and I cleaned my CPU heatsink and that still didnt work so after a bit I decided to do a FurMark GPU stress test and it just straights up crash my pc. My avg temp in windows is (GPU)24 degrees and (CPU) 28 degrees. I even tried another PCI-E cable and that dosent do anything. I also reset the BIOS and I also made sure everything was plugged in properly. I also used DDU and reinstalled my Nvidia and Ryzen drivers. I also checked my windows file integrity using CMD and so far nothing seems to work. I think it could be my PSU but as of right now I cant afford one.
