i had this problom for a few months and read all the fixes over the net. none seemd to work. i found omega drivers for my nvidia card but that didn't work either. i brain stormed and was going to replace the nv4_disp.dll driver with the omega one when i went into my c:/windows/system32 folder. i found that i had 3 of the same driver so i went back and reinstalled the newest nvidia drivers from the nvidia website. after that i went back to the c:/windows/system32 folder an got rid of the other nv4_disp.dll files and kept the one for the newest drivers. and low and behold. i have never had that problom again. so try that. if you have more than one of the nv4_DISP.DLL files in that folder that just might be your problem. so try it. if it works please email me with the subject thanks for helping me nv4_disp.dll. hope you all figure it out this is the only place im posting.
