I just turned on my computer this morning, I use it almost every day. When I start World of Warcraft as soon as I log in my computer turns off, same thing when I open Call of Duty, computer just turns off, is this a RAM related issue? I don't have a virus and it's not a problem with my operating system i'm sure, only thing I can think of is RAM or HDD, but i'm almost 100% sure it's ram, any help?
