hey, i am having a little problem. i just put a 512 MB stick of ram in my computer, before i did that, i had absolutely no problems with it. now, its shutting off randomly when i play World of Warcraft... my question is: can something as little as a stick of ram cause my computer to overheat? i know i need a new psu, but it was working fine until i put that ram in. (my psu is a 160W, and im getting a 400W tomorrow.. will that solve the problem?
