Problem:

- I've been having an issue over the last couple of months with my computer whilst gaming. The screen freezes into a pink, blue or green screen, with vertical lines.
- It ONLY seems to occur whilst gaming, very randomly. I'm finding it really hard to troubleshoot because it can happen 2-3 times a day, and then it'll be completely fine for a few days. It only occurs when gaming, and usually when I've been playing for a good hour or so, at least.

Temps:

CPU
Idle: 40-50c
Peek(gaming): 40-60c

GPU
Idle: 50-60
Peek(gaming): 65-75c

I was under the impression these temps were normal.. the GPU never goes above 80c, and the CPU usually hits 55c at most.

What I've done:

- I've tried to reinstall drivers, different versions of drivers, and even an entire format of my OS.
- I've tried to move my GPU to the second slot on the mobo, and I've tried different combinations for my ram (different slots, single stick..etc).
- Memtest no errors
- FurMark no errors

Spec:

GPU: Sapphire R9 280X
RAM: Corsair Vengeance 16gb
Mobo: Gigabyte Z77X-UP4 TH
PSU: Coolermaster 600w silent pro
Case: BitFenix Neos
CPU: i7 2600
Storage: Samsung SSD 850 Evo

I've no idea what else to try now, I'm worried it might be my GPU failing, but is there any way in which to test this? Any help at all would be massively appreciated!
