The computer I am having issues with is my friends which I built for him recently (November I think), it has been working fine until now ,the computer restarted during the division beta I checked event viewer and found that this was caused by 'nvdlkm driver stopped responding' which I know is a display driver crash. I removed the graphics driver using display driver installer and did a clean install of the latest Nvidia driver 364.51 (an earlier version was installed before around 342 I think) it worked fine . This didn't fix the issue permanently but it worked until a game was run, I could boot without any bsod but I got no signal when I connected over hdmi after a reboot. I could however connect over vga so I uninstalled the graphics driver fully and did a clean install again, this allowed me to boot using a hdmi monitor but the display output stopped when running a game, this time leaving the computer running. I tried removing the graphics card and running on onboard graphics, this worked over vga again, but it didn't output anything over hdmi, even when I installed the intel graphics drivers. I tried different monitors over hdmi even using different cables but having no luck. Because its a recent build it didn't have much on it so I did a windows refresh (reinstalling windows via usb but keeping old files) I tried the graphics card in my own computer and it ran fine. Could this be a corrupted windows update that keeps breaking my gfx driver? or is it more likely a hardware error?
The specs of the system are: windows 10 64bit Asus strix 980, 4690k, asus maximus vii hero, corsair modular650i power supply, samsung 850 evo ssd. All of the parts are at stock speeds and have not previously been overclocked.
I don't know what bios version it is running but I have updated it when I built it and can find out if it is needed. If I'm missing anything or need me to give you more information please let me know and I'll do my best.
Any help would be greatly appreciated thanks!
