I'd advise posting the identical message on a board specializing in your brand of monitor. The manufacturer probably sponsors one that is monitored by one of their experts.
If not, take the monitor back.
If it's still there, replace the video card
A vertical line would almost never happen with a flat screen CRT monitor, but is very possible in a flat panel LCD type monitor. If you have a flat panel, I would strongly suspect the problem is in the monitor, not the signal from the computer. If you have a flat screen CRT monitor, I would suspect the problem must be in the signal from the video card.
Also make sure that you unplug your equipment when there is a thunderstorm in the area.
Good luck.
I took it back and it was replaced with an indentical monitor. First, I made sure it was not an artifact of the signal by plugging in a CRT monitor and then running the monitor without a signal. It was a genuine hardware problem.
The advice about power schemes here is good, but the damage is probably done. Replace it.
Do you have anything close by that might contain a magnet, such as headphones? This used to harm the older monitors. I am not sure about the new ones.
Try a good name brand like ViewSonic. Costs a little more but probably worth it.
Moniters?????
My computer's on-board video card started showing alternating lines of white and gray on the screen, resulting in a washed-out display. There was no way to fix, so I bought a new AGP card to put in the upgrade slot on the computer and everything's back to normal. After a couple of years, a video card will fail. If its not an on-board one, it can usually be replaced. If its an on-board card, it can be by-passed. Hope this helps.
"Flat screen" is a term referring to CRT screens that aren't curved in the front, but they're just as deep as other CRT monitors.
IIWY, I'd take that off-brand monitor back to Circuit City, talk with the manager, and either get a full refund or replace it with a Viewsonic.
Viewsonic is the most dependable LCD flat panel monitor, IMO.
Get an uninterruptable power supply (UPS). They work as line conditioners and can take a number of monitor related variables out of the equation.

I'm in the business and have experienced an unusally high failure rate with flat-screen LCD monitors. I recommend against buying them until the technology advances.....for more reasons than just the high failure rate.
Get a monitor, they work better.
Most displays now have their own drivers, which historically hasn't been the case. I solved one flat-panel display problem by installing the correct driver. Check your manufacturer's website to see if something like that is offered. While the problem that I fixed wasn't a single line, it was a display problem that made it seem as though the monitor was on the fritz.
