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...
hell_storm is right. We need some system specifications. This sounds like a commercial system. If it is, we need brand and model, CPU type and speed would be nice, a list of the original equipment, a list of what you added - including all the peripherals you have plugged in. What kind of PSU? Take the side off and tell us what is on the label.
If you or someone else built it, we need brand and model of all the components used.
It is unlikely that unplugging the printer shorted the power supply. USB devices are designed to be plugged in and unplugged with the power on.
Unplug all the USB devices from the computer and remove the USB card. Does the system work?
Thank you for all of your responses. I moved the computer to a storage room and it took a minute to get to it.
It is a Compaq Presario SR1922x,
Product # EX319AA
Power supply is HIPRO HP-D3057F3R - 300W
I had the following devices plugged in...not sure if all were on at the time of the crash:
1. Lexmark Printer z645 (low end bought from Walmart while traveling);
2. HP Officejet 6210xi All in one printer;
3. 3 external hardrives (SimpleTech, HD from previous computer [in external case], Acomdata);
4. Brother P-touch printer...don't think it was turned on at the time;
5. Wireless keyboard and mouse;
6. 14" flat screen monitor
Running Windows XP Pro
I did remove the 4 port USB card and tried to restart, but that did not work.
I removed all USB devices from the computer and tried to start. That did not work.
I reinstalled the USB card.
Unfortunately, I don't have a spare power supply on hand at the moment.
Also, the inside of the computer was extremely dusty. I borrowed a friend's air compressor and blew a lot of dust out of it.

Just had a chance to take computer to Fry's...ran check on power supply...power supply no good. I'm going to try to replace the ps myself rather than pay the $50 labor. Hopefully that will fix the problem...will post results.
If you have never done this, I suggest making a list of everything you disconnect so you do not skip reconnecting something.
I am pretty sure that you have a top mounted PSU. I also suggest turning the case upside down before you remove the old PSU. Let gravity work for you, not against you.
Take some of the money you saved by doing this yourself and buy a good PSU. Something like the Corsair 400CX or an Antec Earthwatts 380 will do nicely. Or (this will sound funny) look at all the 400 watt PSU's and buy the heaviest one.
