HELP!
I have the same problem.
I have had my computer for about a year and everything was fine until the blue screen of death and NV4_disp message.
Dell Dimention DM 4600, Intel Pentium 4 CPU 2.80 GHZ, NVidia GeForce FX 5200, Windows XP Home Edition. Bios Version 4.34.20.22 BF.
I have talked to Dell Techs for days now, and they are clueless. I did the obvious things that they told me about - - deleting NVidia drivers and reinstalling, going back to earlier configurations, etc.
Can anyone help with this?
