Hello there, hope all is going well.

So 3 days ago I started having 'no signal issues' while playing games like The Division, Days Gone, WoWs & GTA. With that being sad wows is the only one that I have been playing longer without any issues. But as mentioned before I started having issues. First I thought it might be overheating with temperatures being over 35 degrees outside. So I thought that might be the case. But now we had like 18-21 degrees. But yet again having the same issue. After 30 min or so of playing wows I got no signal anymore. Gpu temp was at 61 degrees at that time. On the hotter days it was more towards 77-79 degrees.

I looked online and saw that I had to check the cable. which I did and could not see anything wrong with it. Next I checked if the drivers of the gpu were up to date and they are. Also I cleaned my pc to see if that helps, but still the same issue. Next I saw that it might be the psu that could be the problem. I am not sure how to go about checking if this indeed is the problem.
Are there any other sollutions to my problem?

Please narrow it down. Partpicker has 229 '850w psu' on file: https://pcpartpicker.com/products/power-supply/#A=850000000000
Also, how long has it been in use?

By 'check the cable', they probably meant to try a different one, or replace it.

Are there any other sollutions to my problem?

-Try the gpu in another PC.
-Depending on what the psu is, we may ask you to try a different one.
-Try a different monitor cable.
-Do not use the pigtails, but plug separate PCIe cables to the gpu.
-If you are using a riser device, extension cables, or 90 degree motherboard adapter, make the necessary connections without those devices.
-Relay to us not just the gpu core temperature, but the hot spot and memory junction as well, just in case.
