Question Graphics Card Crash while playing

Jun 30, 2019

Since I have acquired a built pc a few weeks ago, I have been struggling with this issue: Here and there, but mainly while I am playing a game, and typically shortly after it has been launched, my screen goes black and tells me « no signal »and the computer keeps running (I have to turn it off manually).
I don’t think this is a monitor issue as the same monitor works fine with another computer, same for the HDMI cable. I have tried to update the drivers, and to reinstall them with DDU as well, to no avail.

Would you know what to do ?
My Build :
Processor Intel(R) Core(TM) i5-9400F CPU @ 2.90GHz, 2904 MHz, 6 cores
RAM 16,0 Go
Graphics AMD Radeon RX 580
Motherboard msi z390-a pro
Power EVGA 600 BR, 600W

More detailed infos on GPU :

a £40 bronze PSU is not going to output enough for that GPU buy a better PSU
Oh I see... would you have a PSU to advise? Xhat criteria should I look? The Watts?

Edit: And before I do that, is there nothing else to do? To at least try to reduce the issue

but do not hold me to it could be something different but the only way to know for sure is to test or go pc repair shop local one that is recommended
sorry yeah I would for a start get a displayport cable as long as your screen has one make sure to get the right connectors
I can only advise that with my experience I would go with a 600Watt at least gold,4229.html
Evga g2/g3
Seasonic focus/prime
I would recommend an EVGA SuperNova Gold G2 / or new G3 /GS / GQ, Platinum P2 / PS, or Titanium T2 or a Seasonic M12-II Evo or S12-II
GOOD PSU EVGA is a B2, G2, G3, P2, GS, PS, or T2. Avoid the EVGA B1 and G1 series/ I bought a EVGA G3 with 7year garentee
