So my GPU gave up on my totally... I'll try the oven trick after I comeback from holiday, I wanted to upgrade my GPU anyways but never had a need to... 
This is happening on BIOS screen too, so its not a software issue. This has happened before and raising the voltage has helped since the GPU was running fine on stock BIOS with automatic voltage, I've a custom BIOS but never had any issue with it till today.
My Spec
CPU: i5 [email protected] 1.32v
RAM: 2x4gb [email protected] (running at 1.525) Kingston HyperX
Mobo: Asus P8Z68-V
GPU: HIS IceQ 7950@1050/1400 (modded BIOS by khaboom)
PSU: BeQuiet E9 400W
SSD Intel 520 120GB (OS Drive)
Budget wise, I think around £200. I would prefer to go green team again, I've put back my GTS450 1GB card back in for the time being and its still running after 6-7 years? AMD failed after 3-4 years...

) with a custom BIOS that unlocks the voltage and its overclocked by 150mhz on the core and 180mhz on the mem, still running fine and the values are stuck in the BIOS just like my 7950, the only difference is that 7950 has dual bios, the GTS only has 1.
