Dell :: Constant Distorted Image

Hardware:

Dell Inspiron 9400
CPU: Intel Centrino Duo T2400 1.8ghz
Ram: 2gb
Video: geforce go 9700 gs
Audio: Sigmatel?
HD: Seagate 80gb 7200 rpm

Problem: I was using my typing a word document when all of the sudden a pattern of yellow distortion came accross the screen and windows frooze. I tried rebooting windows but even the splash screen that came up right after you turn the computer on is distorted, during startup every image is distorted somehow including the windows splash screen and all shown dos screens(random characters all over the place in dos). It won't boot into windows normally, it gives a blue error screen and then restarts but it will go into safemode (with distortion of course). I tried plugging into two different crt monitors to see if it was a problem with the monitor but they displayed "Signal out of range." I plugged into an LCD monitor and it would display the image but still showed a "Signal out of range." box bouncing around even though it was showing windows in safe mode (still distorted.) I have never seen this problem before. I booted from an xp cd and did a fixboot comand but it still won't boot into windows normal. I uninstalled the video drivers in safemode which would then allow me to boot into windows but I still had the distortion. I reflashed the mobo bios. (nothing changed) Reinstalling the drivers would cause it to crash and then not allow me to boot into anything but safemode unless I uninstalled the drivers. The problem went away completely for about a day and I was able to install the drivers again and everything was working fine but later it happened again. I noticed that while the computer is having the problem hibernation is impossible (doesn't show the option anywhere). I tried replacing the video card (most obvious culprit at this point) and that didn't even work! I'm thinking it needs a new motherboard entirely.
