I was trying to get a Lexmark printer to work and wasn't having any success. The pages were printing out blank. I thought maybe the ink in the cartridges was dried out since I hadn't used that printer for months. I also thought about re-installing the printer.
At that point, I unplugged the printer's usb cable from the rear of the desktop computer and the screen went black - except for vertical lines in the top 1 inch or so of the screen.
The computer was frozen. I tried control alt delete without success. At that point I powered off the computer via the power button. When I tried to restart the computer, it would not restart at all. No power. Nothing.
The printer usb had been plugged into a 4 port usb card that I added over a year ago. It was the only usb device plugged into the card. The other usb ports were used by other devices (external hard drives, p-touch printer, HP printer, etc.).
I am wondering if unplugging usb printer cable shorted the power supply...
Any advice out there???
Thank you,
Jeannie
