Flashing bios in an Aspire 5515 without a working monitor

Hello All, I have a ASPIRE 5515 with the so called black screen of death. I upgraded to Windows 10 and it worked well for a few days but now won't post to the LCD at all. I then tried an external monitor and that worked for 1 or 2 reboots but now it won't post to that either. I've gathered that I need to update the bios. It was at version 1. I downloaded the bios file from the support site but there is not a filename.fd in it. It says to update, to update from a dos prompt command line (which I cannot do as a don't have a screen that works).

I've read a few posts about naming the *.fd file very specifically to something and then booting with the FN + Esc + Power and a thumb drive in the laptop to get it to flash the new bios. Can anyone provide more details on how to do this with the 5515 (where I cannot even find a bios download that has a file named like that).
Any help would be greatly appreciated.
Thanks, ce

Try turning off the computer, disconnecting the battery and pressing the power for 60 seconds.

Thanks for answering. This didn't work. Any other ideas?

Where is the .FD file? I downloaded the bios from the ACER support site but there is not a .FD file in there... What am i missing?

have you ever tried to change the slot ram?

I tried the RAM swap with no effect. From what I've read, I really think I need to reinstall the bios. I've tried several procedures with no luck. One suggested making a crisis disk with the bios which I tried. The instructions were far to vague and I wasn't sure exactly what they were saying.
