My custom pc has recently started randomly freezing whilst gaming, usually not long after i start up a game. A buzzing sound is repeated, there is no response to ctrl + alt + del or alt + f4 and i have to use the restart button on my case. After restart, everything is fine. I have had various issues, so i think it could be somehow motherboard related.
I have a gtx 970, i7 4790k (@ 4.4 GHz), ASRock Pro4 Z97 and a coolermaster Nepton 240M liquid cooler. Any suggestions would be appreciated. Btw, I have the latest bios and drivers for my motherboard and graphics card, have tested my RAM with memtest and have no apparent issues with my hdd and ssd (according to that S.M.A.R.T thing)
