OK so recently I got a new motherboard and CPU (Asus ASUS Z170-E, Intel i5 6600 3.30GHz) and then my hard drive wouldn't boot up Windows 10 after one day of downloading it through a flash drive. Eventually I got a new hard drive (Western Digital Caviar Blue 1TB 7200RPM) and downloaded Windows 10 once more. It did the same problem as before, where I couldn't have it for more than a day without it crashing and not booting Windows anymore. After that I purchased a Windows 7 CD and downloaded that. I'm currently using Windows 7, but the OS isn't detecting my GPU (AMD Radeon R9 290) and I don't know what to do. All I want is to play WoW again after a 2 month hiatus of my crippled PC. Please help asap.

TL;DR: I'm currently using Windows 7, but the OS isn't detecting my GPU (AMD Radeon R9 290) and I don't know what to do.
