I don't know whether this was asked or not (at least i couldn't find) but as the title says the screen gets fixed suddenly and I haven't any other choice except closing the game.for the first time a message box told me that there is a problem with my GPU and I should fix it but I unfortunately ignored the message and now I don't know what to do.(and I don't remember what the message was.I think it was about my GPU cores but I'm not sure) .this happened for digimon rumble arena 2 for the first time and now shadow the hedgehog sometimes crashes.could you please help me?
these are specs
(OS:windows 7(64 bit) - cpu:intel core i3 3.30Ghz(4 logical threads) - gpu:NVIDIA Geforce GT430 - RAM:4Gb-dolphin v2)
