Please download bluesreenview http://www.nirsoft.net/utils/blue_screen_view.html
and post a screencapture if possible. This will help me find what is causing it (Hopefully)
Also, grab CPU-Z and use it to test your computer along with checking everything's temps.
These can help you guys figure out exactly what's wrong.
PSU failures tend to have random bursts of errors and things like that and nomally display no pattern.
Memory (RAM) failures normally have just Memory_Management BSODs along with Irql_Not_Less_Or_Equal BSODs.
I think it's either the RAM, a overheating CPU, or bad RAM, but we can't be sure until I get those screenshots.
