Hello.
Some time ago, I have bought an Acer Aspire 7551G, and for a long time I was really pleased with it, but for some time now I have a problem with it: the screen goes black when playing some games, most notoriously Magicka(I suspected it was just Magicka causing driver crashes, but no change after reinstalling/updating video drivers). This problem also started occurring in other games, such as LoL, which never caused me any trouble before.
After the screen goes black, if I either wait a while or close my laptop screen and reopen it, the image comes back on, although very dark, with way to increase the screen brightness, although the brightness does come back after roughly 20 seconds. Sometimes, I have to restart the laptop for the image to come back.
What could this be caused by? Perhaps overheating? If so, what can I do about it?


Any help would be greatly appreciated. Thank you in advance!
