I recently ran into sound problem on alienware 17r2 with bios a00. I downloaded and installed website sound drivers then problem returned so I used a windows 10 1809 usb and reformatted and when I got back into windows I proceeded to download any missing drivers and also downloaded bios versio a10. I ran the bios file as administrator on ten minuite old windows installation with no other software installed. It got to second block turned block white and froze. I left it for couple hours but eventually rebooted to black screen with no alienware logo. I have been trying to do bios recovery with a fat 32 8 gb flash drive. I have tried many different bios versions even aw15a05 and used the aap10.hdr file name AMIBOOT.ROM, BIOS_IMG.rcv and a fx000064.fd and using the written hdr file aw15a05.hdr and it will read from the flash for about two min after I start notebook by using end with battery unhooked and after about two min led goes solid on flash drive notebook turns off leaving you feeling like it was successful and then still black screen when I reboot. Lights are on but no fan noises unless started using end key. What am I missing to complete this successfully is the file name wrong for recovery, thoughts? Please help. I contacted dell they want 369 us to help me over the phone to recover a bios, not willing to spend about 500 or more Canadian to fix this.
