I reformatted one of my computers a couple of weeks ago with XP, and dispite early problems with I finally got it running well. I was fine tuning a few lingering problems this morning, one of them being how the screen fit my monitor. I'm using a 32" flat screen tv for a monitor, the computer was hooked up to the tv breifly before I reformated it, and the screen fit perfectly (it was the main reason I dicided to get that computer up-and-running again. After I reformated everything was oversized the taskbar was giant, I had to remove items from my start menu (there weren't many to start with) just so I could get "Run" to show up in it, many opened windows were extended off the screen, and web pages were the worst. They were contained on my screen, but the slide bar at the bottom was at half, so trying to read anything online I had to swing the bar back and forth for each line of text.
I went into desktop properties and tried to ajust the resolution (it was all the way to the left). After swinging the resolution to the right I'm now looking at a black screen with a horizontal green line through the middle, and smaller green line flashing in the upper left corner. I've turned the computer off and rebooted, but that didn't do anything. Any help would be great, thank you.
-My computer is Dell about 7 years old
