I have an interesting issue:

-different patterns of single- or dual- colored lines,squiggles,columns, and/or patches appear on my screen, from the initial dos screen (some characters, I believe periods or hyphens, are replaced by garbled characters) an onward.
--Normal scenario: after boot, Windows screen has several columns of lines, then after sign-in, as processes go on and applications run, the screen becomes more and more garbled until either I cannot see anything behind it, or the system slows and then becomes unresponsive.
--pattern and color(s) change each time a new window opens or closes, and even while scrolling through a webpage like this one.
--sometimes the garbled colors are manageable to where I can still see what I'm doing, and other times it gets so garbled I can no longer make anything out, and many times the whole system eventually becomes unresponsive or freezes.
-System setup: Alienware PC, (2002) Win XP MediaCenter SP 3, Nvidia GeForce 8800 GTX, 3GB ram, AMD athlon 64 X2 dual core processor 5600+, 2.81GHz
--AFTER the problem: Tried uninstalling and reintalling drivers, tried unplugging and replugging monitor cables.
--I do not think it is the cable or monitor, since sometimes it works better and sometimes not, it is not a predictable thing, and jiggling the connection wire does not change the pattern(s). Only changing what the computer is doing (scrolling/loading webpages or applications seem to change the patterns)
-BEFORE: Several things have recently been done before the problem started.
--Fans were whining loudly, so we cleaned out most of the dust from inside, being careful not to touch any actual pieces inside.
---Problems did not start then.
--A couple weeks later, downloaded and installed a different Nvidia driver to use a downloaded editor toolkit for a PC game, Dragon Age: Origins.
---Besides the driver, (to my knowledge) the only files edited were in the game files itself.
--Onscreen issues started shortly after downloading the toolkit and driver, and editing the game.

Thank you all for any help, in advance.

have you tried reverting to the old video driver?
