I'm putting together a new build and my machine is shutting down after about 1-2 min of the windows install and sometimes while in bios as well. I've run memtest86+ and it successfully ran though 3 passes with no errors, also it ran for about an hour and a half and did not shut down during this test, so at least my memory should be OK. I'm thinking i may have a bad MB, but I was hoping for some suggestions before RMAing it, especially since it's currently out of stock on newegg. I've reset the bios to default as well.
