You can uninstall absolutely everything (I mean GTA, MTA and every related thingy) and then remove every game folder, cause they are left even after uninstalling (that's why mods are here still after reinstalling GTA for example). Remove:
C:\Program files (x86)\Rockstar Games
C:\Program files (x86)\MTA San Andreas 1.5
You can also remove GTA San Andreas User Files (located in "Documents" idk why)
Then install GTA and MTA again, when everything will be deleted. If this wont help, idk what will
