I’ve been having trouble with my pc randomly black screening on me after it’s been on for a while. The time it takes to shut off is random (between 30 mins to a whole week). But they all happen the same way: the screen suddenly turns black and if there’s sound playing it’ll keep going for like another 2 seconds then cut out. At the same time the sound cuts out my peripherals stop working (I have a chroma keyboard and the lights stop moving in the pattern and just stay stagnant). At that point I have to restart the entire computer. The screen is black but it still has a connection to the monitor (monitor doesn’t dim). My setup is an sapphire R9 290x tri x OC, MSI Z97 gaming 5 mobo, 4 sticks of ripjaws g. Skill 4gb ram, i7 4790k, Corsair acc 750m PSU, and win 10. Thx.
