i recently upgraded my PC with a new motherboard and cpu. It would be working fine for 15-20 minutes of gaming but then all of a sudden my screen goes blank but the system is still powered up. I have a small feeling it might be the bios but i am not 100%.

if anyone knows any solutions it would be a massive help! :)
