First off I have a Compaq S5100NX w/ 2.6 ghz processor runiin windows xp home. Last night when I went to turn on my computer and I pressed the power button nothing happened no noise no lights on the front nothing, I did notice that the greenlight on the back by the plug was on. I have had the case opened and see no loose connections, also the fan in the power supply does not run. Are there any checks that I can make with a DVOM that mighgt help me solve this problem
Any help would be appreciated Thanks

your power supply went kaput. The green light means your getting voltage to the motherboard but that's it. You have a 20 or 24 pin harness that plugs into the motherboard. Take that out and re-install it checking for any loose wires in the plug. That fact that no fans are running means the 12volt rail is not working. If replacing the large plug on the motherboard doesn't work then it's time for a new power supply. Good if you're under warranty, bad if you're not.

and life goes on...

You've got a bum power supply. Buy a replacement and swap it in for the burnt out one.

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?
