Hello everyone, i have been reading a lot about this topic but i cannot figure out what's my problem.
I have a m17x r3 with win7 and since my gpu did not work anymore i decided to upgrade it and got a 765M.
This is what i did:
Since this link for the modded A12 bios in this forum is no longer working, i looked for the modded A12 bios on google and found the one on this post http://portables4gamers.com/forum/topic/18078-m17x-r3-bios-a012-bios-a012-unlocked/ so i downloaded the modded version (second link) and installed it
Starting win7 in safe mode I uninstalled every audio driver and nvidia driver
Reboot and F2 into BIOS, then Integrated sound card disabled -> disable the integrated graphics - Second Advanced Menu ->Video Configuration -> set display to PEG ->F10
I then shut down the computer
Removed the old card, put the new 765M (with thermal pads etc...)
Started the PC and the monitor "lights up" but it stays blank, i see nothing, just the backlight on, but nothing more: pure black
Since i could do nothing, I removed the CMOS battery, waited for 30 secs and then put it back in
Turned the PC on again, now the screen turns on but it stucks on the screen with the alienware logo, the "loading bar" goes from 0 to 100% but I cannot access BIOS, not even boot in safe mode, nor anything else (i read somewhere that this seems like a BIOS problem, not recognizing the gpu...)
If i put the old (non working) card instead of the 765M, i can then re-access the BIOS
I'm really lost, hope you can help me.
Thanks a lot!
