I recently built a gaming pc about 2 months ago that worked great the first 2 weeks then out of no where I started to get these random black screen crashes. The monitor will go black, but it's still receiving a signal, the sound cuts out every time although the amount of time it takes varies but no longer than 2 minutes after initial black screen, and the mouse and keyboard become unresponsive. The HDD light on the case flashes as normal and the fans do not speed up before or after this occurs. I monitor temps and don't do any OC so I'm positive it's not over heating, plus it only seems to occur when web browsing or watching a movie or sometimes when left idle and has never happened during gaming or under any sort of heavy load. I have it set to never go into sleep or turn off the monitor. All drivers and recent updates are installed and I don't have any viruses. Like I said, it seems to happen completely at random, sometimes I can go weeks without problem, other times it will occur multiple times a day and the only way to get it back is to hard restart. I never see any error related to the crash in event viewer, I'm completely perplexed!! Please give me any advice you can offer, I would greatly appreciate it!
