I'm having some head scratching issues with my XFX R9 380, any suggestions would be appreciated. I installed the card in my newly built pc and I couldn't do much, it allowed me to enter Bios but the screen would only be revealed if I moved my mouse. I then tried my gtc 960, and that worked perfectly fine and so I contacted the gpu supplier and asked for a refund. However, I then updated to Windows 10 from Windows 8.1 and the R9 380 began to work, only problem is it only works if I turn on my pc after turning off the plug. I cant just restart the pc, it has to be a complete power down. I'm rather confused, thanks in advance.
