Hey my mom accidently unplugged the power strip from my wall turning off everything connected to it including my monitor, computer, speakers, ect. So I obviously plugged the power strip back in and everything turned back on and when I tried turning my computer back on...it wouldn't. I held down the button for awhile...still nothing. A led light on the mobo says it's on so I'm not sure what my problem is. Also the dimension 8200 doesn't have a power switch on the back so I have no clue what to do now. Any suggestions?
