Hello, I recently got a sapphire r9 280x from my brother's computer.
I use to play CS:GO a lot and didn't have any issues running it with my 6870.
After I installed the new GPU, I sometimes get black screens and it forces me to restart the game.
I think this might be because of my PSU is not giving enough power.
My specs:
MSI 970A-G43
FX 6300
4gb RAM
300gb HHD
Silencer MK III 500W (Bronze 80+)
I've looked at the specs, that PSU provides 38A on the +12v rail, which should be plenty for a 280X.
My guess is the problem is driver related.
I would use a tool to fully uninstall your current AMD gpu drivers, then go to www.amd.com, and get the latest catalyst suit and reinstall.
I reinstalled windows 2 days ago. I had the same issue before so I thought a clean install from windows and drivers would do the trick but the problem is still here, so Im looking for some advise
Well there are a few things that could cause problems. First thing I would look at is temps (if you have any temp monitoring tools with the GPU that'd be handy, or I think GPU Z can do this). Sometimes the fan profiles for cards are a bit too low, letting it heat up more than it should.
It's also worth looking at the CPU temps- as the 280X is faster than your old 6870 it will put more strain on the cpu (I had an issue with my FX 8320 overheating after I went from a GTX 560 -> an R9 280 as the frame rates were that much higher increasing cpu load, invested in a cheap liquid cooler and problems now fixed).
I mean you are correct it *could* be the PSU, although I run my (similar) machine off a Corsair CX500 supply with similar specifications without issues which is why I think it might not be that.
