Hi, since yesterday i have had problems with my iMac, whenever i play the my game on Java, it crashes, yesterday it started out slow, happened like every 2 hours, but right now, when i get the error, only option to pull the plug, and then restart, and i open the game again and it happens within 5 mins, i made a video of what it looks like on youtube. (Btw, its lower half of the screen black, and the top is flickering) I cant do anything anymore, i can pause the music by keyboard, which i couldnt do before on the older crashes from yesterday strange enough, and i can move the mouse, but i cant click anything or w/e. Cmd - alt - esc doesnt work either.. Please visit the video and give me advice, i managed to figure out it has to do with Java, i called my local apple store, they said i should try a PRAM reset, i did it, and after it took a little bit longer to get the error, but still after about 15 mins. This is really bugging me out, since i just got summer and i want to enjoy myself with some gaming.
