Hey guys I need some help. Recently I've been playing starcraft 2 and for some reason my computer screen turns off randomly. I looked up some forums for a some people said ur insides of the computer might be too dusty so I open up my computer and clean it with a duster. I close my computer, turn it on but the monitor doesn't turn on. I tried taking out graphic card and putting it in but nothing. This is extremely frustrating so if anyone can help me I would GREATLY appreciate it. I can't get on my computer for the specifications and I'm typing this from my phone lol. Well, tnks again and pleeassee help!
