So i own a PC notebook HP G61-400SP with windows 7 on it. Recently i dismantled and reassembled the laptop in order to clean its air ways for better colldown purposes. Soon after that i noticed that when i closed the lid (i have it set remain turned on when i do that) after i open it up, the screen freezes, goes black with two kind of pixelated white stripes, then i'm forced to manually shut down the pc for it to come back to normal. If i hibernated it, close the lid, reboot, it's all fine. The computer keeps running normally (i guess) while it's frozen, skype calls and videos keep running, just the display gets screwed up so i'm guessing it's a hardware problem. Thank you since now for your attention.
