Laptop works well if i disable the gtx560m.

Motherboard is new, bought in taiwan (or in china, i don't remember). I live in Italy, Brooklyn NY is a little bit too far from here

Good luck with the repair, feel free to pm me if you have any questions. You can also try to buy repaired units from China, though it takes a bit longer for it to arrive. If it's not repairable they will refund you. Here's a link to an ebay listing to repair the computer (you send the whole computer in). I've used L2 several times when I owned a computer repair shop and never had an issue with them. Though if you don't want to send it out you can always buy another motherboard and hope for the best. L2 computer repair in Brooklyn NY has an awesome automated machine that can probably fix it (either replace bad component or reball the chip). If I was you I would send out the motherboard for repair. I have sold probably 5 or 6 G74sx's with Windows 10 loaded and functioning properly with generic drivers from Nvidia. Please tell me if You have some suggestion The only way i've found is disable the gtx560m, and the laptop run well. I've tried different drivers (old, new) but none of them works. I can't find a correct nvidia gtx560m driver. Yes, i'm experiencing hardware malfunctioning (even on windows 7)
