I was plugging in a new modem and I unplugged my pc power cord while it was on by mistake. When I tried turning on my pc after plugging it in I just get a black screen. I have removed all the components and rest them and the same thing happens. My monitor recognizes being plugged in because it does not say cable not connected on the screen. I have 3 graphics cards and it stays black with all of them. I have also tried just using each memory card individually to see if one was bad but nothing changed. It powers on and sounds normal but nothing happens. Any suggestions?

Thanks

With the system powered down...try flipping the PSU power switch to the OFF position for a few seconds...then returning it to the ON position...and then trying to boot the system.

It should not make any difference unplugging pc power cord with pc on or off { other than a disk check } I`ve done it a hundred times with computers running and no harm came of it. I would check your battery on the motherboard { dead or weak batteries causes bios to return to default settings } then after check or replacement of battery, remove all graphics cards and start with either the onboard video or if no onboard video then a single video card and if that works then proceed with setting up the rest of your video cards as if it were the first time . Oh by the way , I hope you mean an external modem because if you tried to install an internal modem { pci or such } with pc running then you have shorted you pci bus and your motherboard is toast.
