Update: never mind! MSI afterburner turned out to be corrupted. Running my stable overclock again after a fresh install. I'll leave this post as is in case other people run into this problem.

Hi, I searched for a while but couldn't find a solution for my problem.
Yesterday I tried overclocking my GPU, a MSI R9 390 gaming, for the first time. I used MSI afterburner for the overclocking and Unigine Heaven for testing. I didn't increase core voltage and temperatures didn't go over 80℃.
All went well: I got my core clock up by 100MHz stable (went higher but got artifacts). Then I overclocked the memory as well; also got this up by 100MHz without any issues. Then I tried increasing it another 20MHZ, this was running stable for a couple of minutes but then it crashed. Screen went black and I had to restart my pc. After this restart, my previously stable clock now gets 19fps in Unigine Heaven in stead of 123 average. Fresh small overclocks (+20 core, 0 memory for instance) also get very bad results (around 30 fps). Standard clock however performs the same as it did before, around 113 fps average.
I did some research and read that it might be the driver. I uninstalled it with the help of Display Driver Uninstaller and installed the latest version again. However, this did not change anything. So what is the problem?
