Was using my desktop yesterday as normal when the screen goes black. Notice the monitor led light is orange. I check the tower and the noticed that the power led light was off but all fans are running. As recommended I did hard reset, pushed the power button and all fans go on but again the power led light is dark and there is no signal to the monitor. Left it on for 5 minutes and suddenly the computer boots up as normal. After a few minutes of use the monitor goes black again and now I notice the power led light on the tower is orange. Also as recommended I updated the PSU but still experiencing the same issues. Any help will be appreciated!
