    Hello Guys this is my first Post after reading several threads here seems like a nice place.
    My Notebook is an Acer Aspire 7750G.

    What originally happened ???

    - I have downloaded a modded bios A_A_7750_P5WE0117_UlkMenus_ByCamiloml.exe from here bios-mods.com (under insyde)
    - i flashed it worked and then i set ide graphics to Enable (in the modded bios)
    -
    Im unable to boot normaly in Windows The Notebook keeps restarting after 5 seconds ( infinite boot loop) unable to get to windows or the bios only in Recoverymode it stays on with the FAN-Speed at MAX

    The goal was to be able to choose between onboard graphics and the graphic card i know it was stupid now *facepalm*




    Mission Bios Recovery


    - I used Andys Tool to find out the name for the FD file and put it on a USB (The same files with several other names also as stated in the insyde bios recovery thread)
    - Used the FN+ESC Method
    - The USB light is showing for 2 secs and then nothing is happening ..


    Questions


    1 - Does that mean he didn't find the right file on the usb?
    2 - Since it lighted up i assume it has been read?
    3 - What might be the right filename otherwise?

    USE THE FILE FROM WINdows folder.
    install 7-zip and right click P5WE0113_winflash.exe then extract.. and there u have P5WE0x64.fd 4224KB ( if u notice the file is already named properly .fd )

    not 4096 from dos the BIN = BAD !!


    also very important.. did u create crisis disk in XP or 7 ?
    copy flas**t.exe to usb and P5WE0x64.fd after crisis disk is made. (if it even needs crisis disk made.. some dont.)
    in that case the usb brand matters.. i find sandisk to be best type.

    Thanks for your suggestions! : )

    - i did like you said and i also created the fd by myself using dos commands both fd files didn't work.
    - The crisis disk just gave me an empty usb I thought its because it's only for Phoenix bioses?.

    So far no luck for me i only got one 16gb maxflash usb 3.0 drive.
    It's lighting up in Crisis Mode (FN +ESC) but then nothing.
    I assume it should be read by the notebook and then shutdown, wasn't the case so far tho o_O

    Could it be because the USB 3.0 usb?

    empty ? strange.. make it in xp also use sandisk 2.0 (sandisk has worked for me on many laptop models)
    after disk is made.. then u copy the files. disk might be empty cause hidden System files.
    i dont think it needs crisis disk..
    says copy the file Bios.fd only

    No luck so far i think the same as you insyde bios only needs the right bios file with the right name for recovery

    I tried with a bootable USB anyways well no luck. With another version of the win cris programm i managed to do it. Showed up as floppy ( Fat formatted ) again unsuccessful :(

    New /Last updates
    - Removed both rams put in different slots.
    - Used CMOS Jumper
    - Removed cmos battery completely (bios settings should always revert on every boot)


    No sign of a change
    If the complete Ram is removed it doesn't bootloop but stays on
    Well i tried it : )

    Thanks for your Suggestions on solving the problem LatinMcG

    Hi, I've exactly same error
    I've tried removed all, flash with USB (2gb in FAT and FAT32) on USB2.2 and 3.0 port and I tried to burn CD.
    Nothing work... I've with 4 différents name for the BIOS :
    P5WE0.bin
    P5WE0.fd
    P5WE0x64.bin
    P5WE0x64.fd

    When it start I can see disk drive work (with or without cd) and the USB seem to no work because I never see any light...
    have you another idea ?

    I had the same problem. None of things i tried worked. A user at InsanelyMac (nai22) repaired my Laptop. Maybe You can contact him at InsanelyMac.
    I cant post links, search for "6650M Graphics Enabler / DSDT", you'll find him at page 4
