On older PC's that happend every time. On my first PC i was having that problem. Was from the video memory it was lower 256 mb then from the gta sa mods. So don't install mods like high texture pack new skin weapons on night vision ******s high resolution car skin or ENB Series. if you try this and isn't work try to reinstall your windows

Best windows
Windows Xp SP3 32 mb
Wwindows 7 Proffesional 64 mb
