My Dell dimension 4500 desktop was accidentally shut off at the power strip and now I can't get it to power up by using the power button. THe light behind the button will light up but after holding down the button for about 15 secs, it goes out again. Still no power, though. There are no diagnostic lights at all on back of cpu. Help! Do I need to replace the power supply? I have tried to get to the power switch board but can't figure out how to do so and am afraid to mess it up.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
