Montior took a crap?

[Bukem_]

24" dell may have just gone bad. Everything is a flickering hue of pink red or purple. The black border of my background now looks like the black and white fuzz on tv, only its red and black. I can still make out what images should be. I can't seem to take a screenshot either. All cables are in place. Looking for when I bought the thing to see if its under warranty. Also if anyone knows a way to get screenshot besides print screen, ctrl-v let me know pls.
