So, I was playing a game of Dota 2 and suddenly blackout occurs for like 3 seconds. Electric is back on so I started the computer and and it went to bios. Now, this is not the first time that I encounter this problem. I know i had to do a hard reset on my computer by unplugging all my devices(keyboard, mouse and headphones) to the computer and waited 5 minutes. After that, it may start Windows 7 or not. This problem is getting annoying to me. I do not know which of my devices has a faulty and now all my friends lost the game because of me . HELP!
