My friend reformated my computer.. I dont have the windows xp disc on me either. I have a problem with my motherboard. The NV4_DISP.DLL error is caused by an outdated motherboard driver i guess? The problem is i dont know how to update it , because i went to the website to do it and i just got a weird download that goes into dos. I have a Gigabyte GA-7IXE4 and i cant figure out how to update it. I cant play any games on the internet and its making me mad. Please respond if you know what to do or how to update my driver step by step or something. Thanks
