Monitor Problem - Need Help Plz

Hey guys,
Here is my problem. I turned my computer on in the morning, then I went out (Like I always do). Then I came back about 4-5 hours later. Then when I looked at my monitor out of nowhere it was all messed up!!!! There is all these gray lines across the screen, the bottom is darker than the top, and color is bright. Nobody had touched the computer the entire time. I checked my monitor and graphic settings everything seems to be normal.
Any ideas on what is wrong???

Details-
17 inch crt monitor by dell
Run a screensaver after 45 min
Monitor turns off after 2 hrs
Geforce 256 32mb (with latest drivers)

how old is your computer?

it sounds like a major problem to me!

better check its warranty and it has already lapsed, better refer to a qualified technician unless you have enough background in crts!
these things are kinda dangerouzzz!!
