PC Games Keep Crashing Ever Since GPU Switch

Hi All,

little bit stuck at the moment and getting a little frustrated now, I recently bought a GTX 970 and installed into my machine to replace my Sapphire R9 280 but my games kept crashing on me - at first I thought it was the drivers not being installed properly and so I re-installed them, this didn't work and I tried re-installing windows - again this didn't work,

I got a blue screen saying "SYSTEM_THREAD_EXCEPTION_NOT_HANDLES (dxgmms1.sys)" and so I googled it, it seems that my MB and CPU aren't compatible for my 970 so I switched back to my R9 280 which at first was going alright but then I realized my PC was running slower than usual especially after a clean install of windows, so I upgraded to windows 10 to see if that did the trick but was still running slow, so I found out that my SSD hadn't been partitioned and so I went to disk management to partition this, which it fixed but now I can't boot off of my SSD and have to put to my other hard drive as no #1 in the boot order and then when it finds no OS it goes to my SSD next and loads windows - and then after I've got my hard drives working (sort of) and fresh install of windows 8.1 pro again, my games are STILL crashing,

I've already monitored my CPU and GPU temperatures whilst on the games and they don't go above 50 degrees so I really am confused as to what's going on, any help would be greatly appreciated, PC Specs below:

MB: MSI 970 (MS-7693) AMD Chipset
CPU: AMD FX 6350 @ 3.9GHz no OC
Heatsink: Coolermaster EVO 212
RAM: Kingston HyperX Blue Fury DDR3 16GB @ 1866MHz
GPU: Sapphire R9 280
PSU: Corsair 600w
HDD: 1TB Seagate
SSD: 120GB Kingston HyperX SATA3 3K
OS: Windows 8.1 Pro

Sorry for rambling - again any help on this would be greatly appreciated.
