Hi guys. For like a week ago, me and my friends bought a game on steam called Dungeon Defenders. Then we was talking on skype, having an awesome time. But suddenly my screen just turned black. And the last half second of the word my fra said, got repeated in my headset. And it played the word 100 times per second. And i think my pc turns off too, but it immideately restarts, so i really dont notice it. And then nothing happends, the only thing i can do is to turn off my pc. And now when i try to turn it on (The lights works, and the fan's start) the screen just turn black, and nothing happends. I haven't tried to clean it yet. Cause i dont really think its the problem. Help me My big brother said i should update my GFX or something like that (How should i update it, if i cant see anything im doing on the pc ?) with this: I can't set the link in. The site does not allows me too it. But just ask, and i will send it. I need some help Im really sorry for the bad English it can be hard to understand. Thanks in advance.
