Right, I've been working on this for the best part of the day, and its annoying the fuck out of me;
I can no longer access single player, or samp, it crashes halfway through loading, anyone got any ideas for any fixes; I've done the following
Reinstalled 18 times, tried three different gta_sa.exe's, tried a hybrid gta_sa.exe made by myself and a friend from Rockstar North (I have Rockstar North trying to help me :L) Renamed directories, reinstalled a further two times, Updates my Graphics card driver, took out my second monitor (causes SA:MP crashes) spent an hour scouring the samp forums to be told to "rename directories" again, trued that three more times, re-installed a further 3 times, got pissed off, tried another of my GTA:SA discs, and none have given any help.
I'm running Windows 7 Ultimate 32 bit, and my computer kicks the shit out of the recommended requirements for GTA.
If no one can help, I'm going out to obtain an XP disc.
