Hello all, just built a new rig and it seems to have a hiccup that is a little over my head.
The PC will start-up and run normally for a little while (up to 10 minutes), until the monitor cuts to black and displays "DVI no signal", which will last until the computer is restarted.
Despite the display giving out, the computer seems to keep running apps (assumed by checking a large download's progress before signal loss and then after a later restart).
So far I have tried many restarts, uninstalling/reinstalling the drivers/OS, disconnecting extra components (second GPU and second RAM chip), using different displays connected to different GPU ports, disabling the integrated graphics and asking it really politely to work, all with no result.
I'll try my best to answer any questions quickly, and I really appreciate any help you all can give.
