There is a very long time that I search an issue for the problem of infinite loop, nv4_disp.dll, ...
Now I think that I have the solution ... It's work for me !
I load the defaut options in my bios.
Then I set my Ram timing to Turbo, my latency to 2, I enable "read around write" I set my AGP aperture size to 64 and I disabled the AGP 2x !!!
Yes, I know I lost a lot of performance by disabling this option, (AGP 2x) but it seems work without it ! It's crazy !
So I made a lot of test, and if I enable the AGP 2x, directly, when I boot my computer, XP don't boot up and I have the boring message "infinite loop , ...".
So I think that it's the AGP 2x which cause the problem.
What do you think about that ? Is et possible ?
Try to disable this option and say me if it works for you !
Thank
(Sorry for my bad english :-)
