Thread Stuck in Device Driver Update Bios

Hi guys ,

I currently have an Alienware 15R3 with a recurrent  (BSOD) "Thread Stuck in Device Driver ".
It recently went worse as I cannot boot into windows without this BSOD coming up.

So I have decided to update my bios (currently in A06) through safe mode.
However Murphy's law strike again as i get the "Unable to Load driver" error message when I execute the Bios update file.

So i have decided to set up a Freedos on my USB stick and I copy the Bios Update file downloaded from Dell website in order to execute the Bios Flash Update directly from the Bios (F12 on launch --> Bios Flash Update) .
However , another problem strike,  once in the GSET Bios Flash Update I cannot use the left / right arrow from the keyboard (only the ups and downs work) in order to select the bootable disk and run the program. I tried to plug another Keyboard through USB same problem .

My Bios is open and I have no restriction in paramter of anykind.

This is a story when everything goes wrong , so if anyone can help me I would really really appreciate .

Thank you guys and Best Regards

Guillaume
