PLZ HELP! After playing games for a period of time,( an hour give or take), the screen detects no signal, and sometimes my gpu fans run on max. However, audio, leds, and fans still on. 

Its not an overheating issue, temps of both cpu and gpu are around 40-50 degrees. This rarely happens when im using computer for general usage, however when gaming, it 'crashes'.

Please help

It sounds like a VPU lockup and failed recover, usually due to insufficient power or overheating. 50°C sounds very low for an HD 7950, so I would double check that (use MSI Afterburner to log temps), and also use the program which came with your motherboard to verify your 12v supply under load is not dropping below 12v (below 11.8 it starts causing issues).
