I have 2 4gb sticks of ram in my pc. A couple of weeks ago it started acting funny and every time I've started it up lately it says "cpu or memory has changed" F1- Setup F2-Defaults. So I thought maybe one was not completely pushed in so I pushed on them to make sure they were in and now my computer will only start up with one of the ram sticks. If both ram sticks are in it goes just keeps shutting down and restarting continually. It also blue screens sometimes "error irql not less or equal
