Im using the MSI R9 270 2G card (sort of using.. because of the existing problem) on a WIN 10_64bit computer.. The mobo is MSI Z97 Gaming 5 +(2x4GB Kingston HyperX memory) And NO MATTER WHAT I DO - I always have the black screen as soon as I instal ANY gpu driver, new,old - its the same! Im not a fanboy.. or someone that will fight with people over TEAM RED vs TEAM GREEN talk.Who is better, who is worse.. but READ: AMD,THIS IS HOW YOU LOSE CUSTOMERS! My card is OUT of the case,now.. because is USELESS. I don't know who is to blame AMD or Micro$oft! But this card work just FINE before! Win 7 and Win 8(8.1) But just recently stop working. SO I JUST HOPE (and i know im NOT the only one) THAT YOU FIX THIS THING WITH THE NEXT UPDATE! This is just frustrating! I DID EVERY SINGLE THING I COULD DO TO SOLVE THIS MYSELF, read who know how many posts online.. from people like me and NOTHING happend! And I would HATE to see an generic answer - to try to clean install the latest drivers because NOTING fix this! The big letters is so that you could see YET ANOTHER GUY WHO IS COMPLAINING ABOUT THE SAME ISSUE,SOU YOU FIX IT ASAP!
English is not my language, so I'm sorry if i didnt wrote it 100% correct - but EVERYTHING is 100% TRUE!
Nobody doubts it's all true, so relax...;)
It sounds like a simple matter of the card not syncing to the resolution and refresh rate of your monitor...evidently, the driver installation is installing the incorrect monitor driver and bam, you lose sync and you get a black screen.
When you boot to Windows *before* you try and install a gpu driver, what do you see? You see your normal desktop, correct? Answer here is important. If you answer I'll suggest a couple of things...
Next obvious answer is that you got a bad card and it has stopped working, but I think the solution above is the correct one...But if setting up the right monitor driver doesn't work, contact the seller of your card and get him to send you another one. It's rare in my experience, but it does happen. Some companies think nothing of selling a warranty return as if it was brand new, etc.
