Sick of losing my game progress, today I installed XP Pro on another parition and installed the game from there. Last week, the crashes started to hapen after I play for 30 - 40 minutes, and it also always crashes whenever it rains in game. No issue, I thought because Windows 7 isn't officially supported. It used to crash only once every 2-4 weeks. I had GTA SA installed on my old PC (specs below) with Windows 7 on it.
