I need a little help my M18xR1 original gtx580m cards cooked out so I thought I would buy a pair of gtx765m cards and stick them in but all I get is a blank screen (you can see the screen light up) but nothing else so I installed one of the fried gtx580s in and flashed the 05 unlocked bios that went well but my gtx765s still don't seem to work? 1) what do I need to do to get them up and running and can they be made to work in this laptop I see someone else got gtx780s to work so what am I missing:upset:
