RX580 crash

[Daan._official]

So I bought a sapphire rx580 nitro + about a month ago. Installed it and everything worked fine except that when booted into windows, the fans weren't spinning at all. 

 

I installed msi afterburner and just put the fan control on manual 60% and that seemed to work. 

 

I'm into overclocking and since msi afterburner is pretty much a safe overclocker, I used it to boost the rx580 to 1500 mhz core speed with 9gbit memory speed. Read that most cards should be able to get that and mine did too. Played some warzone and seemed to be stable. No high temperatures or anything out of the ordinary. 

 

Now yesterday I was starting warzone when suddenly the screen turned light brown and crashed. I restarted it and it booted into windows but it kept crashing.

 

I tried to turn off the afterburner overclock, but that also crashed it. Booted up into bios and that works just fine. Sometimes when I boot it works for some time (like 3 minutes) but it keeps crashing into either black screen, light blue screen, yellow or I can see screen with all these colors on it. 

 

I unplugged the pc to do a hard reset but crash keeps happening. 

 

Setup;

I5 4670k oc at 4,7 ghz

Z97 mpower max ac

16 GB ddr3 1833 mhz

Thermaltake 530 watts, which is on the low side, but so far it seemed to be working fine

 

 

Any suggestions?
