I have a 1,5 year old pc (intel dual core E8400 3.0Ghz, 4 gb ram, Nvidia 8800GT, XP sp3)
A month ago he started to have nv4_disp.dll errors. When i play a game for 5 to 60 minutes, the screen freezes and the textures get messed up (but the sound is ok). After a minute or so, i see the desktop again in 640*480 resolution with 4 colours and the message the image functionality (don't know the exact translation in English) doesn't work due to nv4_disp.dll and i need to restart to restore the old settings.
I've already did a clean install of windows XP. (i don't see exclamation or question marks in the system management file)
I've updated all my drivers.
I've cleaned my cooler.
I've disabled the card's hardware accelerator, but then i can't game anymore.
I hope somebody knows the answers, but thanx anyway.
