I built my computer about 2.5 years ago with the help of this forum. Everything worked perfect until a few months ago, when my computer would go black. The led lights would be on, the fans running, but not display on the monitor. When I held the power button on the front of the computer, I could force the power to go off, but when it came back on, there would still be no display. I could restart the computer, by turning off the power from the power button on the psu and it would work when it turned back on. My computer was packed with dust. I blew it out with a can of air and it worked perfect until today. Same thing happened to me today. My computer does hibernate, but I never turn it off. This issue happens when the computer hibernates. What do you think I need to check to fix this issue? My computer is still dust free. I checked my hardwire profile and did not see any errors.
