Hello,
I've seen many people getting trouble with mods,if they are using low level computers.
Then for removing mods,they need to Uninstall the whole Gta Sanandreas.

But if you create a backup you dont need to uninstall the whole game.
Young Generations is providing mods which do not crash your samp.
But low level computers may be laggy.

Before installing mods,
You have to back up your models folder.
Go to Gta Sanandreas.
Copy ''models'' folder.
And paste it somewhere you can keep it as backup.
When ever you feel to remove your mods,just replace the backuped models with modded models.

If im missing something,please tell me.

Regards,
Lordz.
