i tried downloading some 3dfx files from the site but nothing worked, can someone give me help?
thanks in advanceohh ho ho i was replacing my opengl32.dll with a few that i downloaded from the net thinking i was smart, and it turns out i got 1 that must not be very compatible because even games such as diablo2 wont run, please help asap, because i seem to be damaging my computer by trying to help it  Can you use system restore to a date before you got adventurous and hosed your system?well that might have been a good way to get back to point A, but im looking in my system restore file now and it says "there are currently no restore points available". and wont let me change the month. any suggestions?ok i was able to get an opengl32.dll that seems to put me back where i was in the first place so thats a good thing i think. i got 3dfx voodoo 2 or 3 and windows xp, i once fixed this problem by replacing some dlls but that was long ago and cant remember which ones other then opengl32.dll if any i replaced. i cant find the site that told me how to fix it either. this is really a last resort for me so help is much appreciated, thanks again.Update your video drivers.arg, the reason i am posting for help is because i am *stupid*. i tried to update my video driver and i ended up almost killing it. they give me thousands of files and i dont know the right one to choose.To INSTALL the new drivers we must first find out what video card you have.
Download & run Everest, it will tell you & then you can tell us.
http://www.comcen.com.au/~fed/everest.zipWithout the correct drivers how would you even expect it to work correctly? Why should it? How could it?  alright i hope this is what you guys are looking for. i can post other INFO if you need it, just ask.Uninstall the present drivers and use this one:

https://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&folderID=293sorry, but how do i un-install my current drivers?Is it in Add and Remove Programs in Control Panel? If not, just delete it in Device Manager. Use Safe Mode if necessary.
