Hello everyone, I just joined today. I didn't know who to ask or where to go to get info on Windows 7 so I thought I'd try here. I am no computer genius and I need help. I recently had Windows 7 installed on my PC and now I when I try to maximize a video on You Tube or a game on FB my computer reboots. I do not get an error , but it goes to the black screen where it says "Reboot Window Normal, Safe mode, etc... If anyone knows what the problem could be I would be sincerely grateful. Thank you and have a great day!!
