So i recently ran into a problem on my pc as i tried booting it up after being away for a few days , it started up fine and after id say probably 30 minutes my screen would go black for 1 second and turn back to normal i decided to reboot and see if that solved the problem but to no avail , now when i try to boot my pc up the bios flash screens resolution is changed to 1360x something and when it tries to load into windows the screen goes black and says no signal? And if i do manage to get it on 20 seconds after login my screen goes black and i heard a sound but i cant see what the popup is since my screen wont turn back on. Could this be my graphics card turned sour on me or what could be the issue? Please help , Thanks.
