Hi there this is my first post. I installed a gtx 765m in my m17x r3 and couldn't get the machine to post. I would only get 8 beeps. The system did post with integrated graphics enabled but would lock up right after the loading bar during post. I could not get into bios. HD Audio has been disabled in bios. I am on official bios a12. The 765m did come with its own x bracket and I am upgrading from a 560m. I did reset the cmos multiple times and it didn't affect anything. I am almost sure the card must just be faulty but I wanted to know if anyone else had an idea about my problem. Thanks, glad to be here.
