N4V_dll error, then crash

After some lengthy work on getting my Nvidia card to work, and after a try with ATI, I am now facing another problem

To make it short, I was having difficulty getting my Geforce 5500fx to put out any quality graphics. All of a suddon, after trying to get a different ATI card to work, with no success, I re-installed the nvidia card and it works perfectly! Or so I thought.

I can have the resolution as high as my monitor allows and all the game settings about half. The quality and performance is very good.

The problem, After about 45 minutes of playing GTA SA the screen froze. I tried again and it froze after 15 minutes, then again and it only plays a few minutes. I had this problem before and posted, and it was thought that I had not enough RAM, and that my card was overheating also.

I bought a duel channel 2x512 corsair set, the good ones, and I have a 120mm fan blowing directly on the card.

Now since I shut off automatic restart, I can see that I get the N4V_dll error. It has to do with the graphics driver. I have been doing research on this and am told I need to turn the AGP down from 8x to 4x. For some reason, everytime I switch to 4x the computer screen goes black and I have to restart. I am not finding any information out about that problem. I am using rivatuner to do the change.

Does somebody know what might be going on here?

Mmm, sounds like a case of driver conflicts to me.
Try uninstalling all of your video drivers, run DriverCleaner Pro/PE/Platinum in safe mode, install whatever drivers you want.
DriverCleaner Pro is free, but is not supported anymore by Spike, so you'll have to search around for links for that. However, PE/Platinum are newer and thus provide better cleaning, etc.

nv4_disp.dll BSOD could be just about anything really. The first thing to check for is definately the display drivers. uninstall and reinstall like fobis said. if you continue to get them, then update your chipset drivers as well. There might be some sort of conflict between the display drivers and the chipset drivers. If that still doesn't work, the next thing to try would be to update the MoBo's BIOS. From there, the next thing to try as last resort would be to format the machine. *IF* you are still experiencing nv4_disp.dll BSODs, then exchange the card. might be some faulty circuitry or something within the card.

OK, I have tried various drivers, same result. I have also updated the chipset drivers. I just installed this windows xp pro on a new HD.

I have not updated bios, I have been told it could be tricky and not recommended I do myself if I have never done it before.

I had this error before on my old OS also. Then I installed this new OS on a new HD.

I have been on the nvidia forums and there seems to be a lot of people with this error, mostly with the GeForce series 6 and 7 cards. That is where I got the changing of the AGP from 8x to 4x. I am having difficulty attempting this, and getting a response on that forum sucks. I thought maybe someone here could help out since this site rocks.

Seems that was the fix on a lot of the problem posts, but nobody seems to explain how to go about it. They just say "to fix this error, change the AGP setting from 8x to 4x." No explaination, no tips, nothing. Like I said about responses, half of them don't even get answered. This is in Nvidia forums.

I hate to start switching drivers for the card again, last time I was doing that, for some reason I lost all performance and could barely play anything on here. I have it working great now, but still get the error, and lock ups.
