Please help! (Grand Theft Auto: San Andreas)

Hello, I would like to ask you for help! In Gta you play for a long time, but in this case I have first. So either I'm just going on foot or going by car, or flying in an airplane, at some point, I have all of two seconds, the screen goes out. The monitor does not turn off, because the still burning button. It is possible that all the matter in the mod, but for prevention, I wrote to you. Thank you.
