So iv had this problem for a while and have put aside my pc and been using my g73 (OMGMYLOVE).. But it's time I start to focus on this since Iv already put so much money into it, (iv just been lazy with a working gaming laptop) So while I game my monitor will shut off and the pc will stay on, I have not a clue as what it might be. I thought it might be from running 2 crossfire cards but I put them in seperetly and it still happens. It's odd, I played bf3 all on Ultra and nothing happend, but the second I start playing dirt 2, BOOM.. Or crysis2, Im running a 1000w Psu, with a i7 920, 10g'sddr3. and a Msi x58 pro Mobo. Oh and 2 HIS iceq turbo X's 6870 and 6850 in Xfire. Iv run some test with OCCT but it's kinda like another language to me.. Maybe I could post them on here and someone could help me, Im about to purchase a 580 in hopes that does something. Im %95 sure nothing is faulty.. But who knows. Thanks anyone who might be able to lend a hand!
