Read over on operating systems about my buying a new motherboard/CPU etc. because of problems I encountered that were primarily about video appearing and disappearing.
After loads of troubleshooting that culminated in my deciding my DP55SB intel board was dying, and replacing it with a new DH67BLB3 and an i5 7500K. With the new board and system going I began experiencing video loss at times. Ran through a series of trouble shooting new system thinking I had brought something over to the new board when I restored the image. Finally hauled out an old 17inch Sony monitor hooked it up and cured the video loss problems - - - my 3 plus years old Asus monitor is faulty. If allowed to go to sleep, it refused to reawake giving me a black screen that I would hard reboot and sometimes recover video and sometimes not. I blindly (sic) struggled to get my old system to work properly for a couple of months now when the problem is the monitor.
I never gave a thought to the monitor because when it worked it had the usual perfect picture clear as a bell - except when it didn't work. Lesson learned and I'm passing it on for what it's worth. Should I have problems in the future, one sure troubleshooting step will be to switch out the monitor.
The other sad story is when disassembling the old system I found that in cleaning what was excess thermal grease from the socket, I had gotten some accidently under the socket structure and on the many little pins on the CPU socket. I tried to carefully clean it away from those little pins - and thinking the board was shot I wasn't as careful as I possibly could have been. I damaged some of the pins - I've ruined what was possibly a perfectly good board (the onboard lan failed shortly after I bought the board and I used an intel PCIE lan adapter).
Well that's my heads-up for the year. What acts like a perfectly good monitor when it acts right ----could be the source of your problems.
