Hello everyone, i would like to ask if anyone knows what could be the problem i'm facing here. Well, i have an alienware m17x R1, with 2 GTX 260M SLI, well, i am not new on this, so you can avoid asking me about driver or anithing else. (the motherboard is an nForce 730i). Ok, so the problem is: When i run the computer there is a chance (%50) for the computer to detect the secondary video card, i mean, it just disappears, not visible on device manager, not like unkown device or like defective one. This isn't driver related or OS related (same happens on Linux). The big question is: ¿Could it be the SLI Bridge? or that only makes fail the SLI and the card should always be visible?. Thanks a lot.
