Problem
Over the last two weeks or so, I have been experiencing what began as intermittent hard crashing while gaming which can only really be described as a hard lock up. Everything is still visible on the screen, but it will not accept any input at all and if a sound was being played at the time of the crash, the speakers emit a buzzing sound as if it's stuck at a particular point in the sound track.
It also very occasionally happens outside of gaming, mainly while watching videos. It never crashes if I'm only doing anything basic like web browsing, photo processing etc.
To add a bit of history, a few months ago I was getting regular BSODs which I pinned down to the graphics card. A full AMD uninstall / clean-up and reinstall of the drivers fixed this and until this started I had no issues.
What I've tried
Spec
Windows 7 Home Premium 64-bit SP1
Intel Core i5 2500K @ 3.30Ghz
4GB Single-Channel DDR @ 808Mhz (9-9-9-24) - Corsair Vengeance - I did have dual sticks but one failed a few years ago and I've never got round to replacing it
ASUS P8z68-V PRO/GEN3
1GB ATI AMD Radeon HD 6850
120GB SanDisk SSD, 0.5GB WD SATA3, 2x0.5GB WD SATA2 in RAID0 config, 2TB Samsung SATA2
On-board audio
Opinions on what causes similar issues for others seem to vary the more you read across the web and include the GPU, CPU, Memory, Motherboard, PSU. It's the fact nothing has really changed that makes me think something is failing, I just can't figure out what. Thanks in advance for the help, if you need me to provide anything more specific let me know.

What I've tried
Uninstalling / reinstalling GPU drivers, chipset drivers, sound drivers
Memtest86 (12 hrs) - no issues
Prime95 (2 hrs) - no issues
FurMark (15 min) - no issues even with sound playing simultaneously and temperatures rising as high as 85C, much higher than when it crashes under gaming
Monitoring temperatures - the below image shows the temperatures at the time of a particular crash
