So ever since i got my Hyper 212 EVO my PC while standing upright after a while of gaming will crash the system to a blank black screen, but everything on the PC is still running (I dont see the mouse the game noise nothing.) But then when i lay it on its side it will not do this, is it the CPU heatsink stand or whatever causing this problem?? I was thinking the EVO is to heavy for my cheapo motherboard.
