Hi. So I made a big mistake, updating my bios to v1.32. Now my graphics card (nVidia GeForce 840m) does not work. When I browse internet or write code, its ok, but when my laptop decides to choose nVidia card for use (gaming), the screen freezes in a few seconds, and then I can do nothing, often it ends in BSoD (nvlddmkm, VIDEO_TDR, DPC WATCHDOG VIOLATION). My laptop specs:
Laptop Model: Acer Aspire E5-571G-52VR
OS: Win10
Graphics: Intel HD Graphics + nVidia GeForce 840M
RAM: 12GB
The things I did:
- Uninstalled (with DDU) and installed again the nVidia graphics driver (there is even one, which came out today, tested it already)
- Reinstalled the game many times
- Reinstalled Windows (keeping the files) + checked for both not updated and updated nVidia grahpics driver + checked for both old and new game installation
- Reinstalled Windows (removing all the files) and again checked for both possible ways for driver/game
- I did return to default BIOS settings (v1.32 stayed the same)
- I managed to downgrade to 1.31 - still the same
- Did dozens of restarts, plug-out/ins
- Downloaded a nVidia driver from official Acer site, (was 353, mine was 370 something (from 15th Nov 2016))
Can I do something about it? Cuz I guess I would have to downgrade my BIOS... (dunno what was previous version, but the oldest I can find on acer site for my laptop model is 1.09)
Hello guys first of all i've done some researches on forum and i couldn`t find any usefull information about my laptop model Acer Aspire E5-571G,only one topic from 2014.Am willing to pay or i can buy myself this "chips" from ebay but i need information.
My bios is Insyde Rev 5.0
And i`ve update my bios to the last version 1.32.
If anyone need any other information im here.
I make these because i don`t have the money to buy a new pc and i want to buy only a gpu and connect it as eGPU but the problem is that i got already 2 gpu one internal Intel 5500U and the other one is nvidia 840m.
THANK YOU

Good afternoon, I'm using google translator.
I have an Acer E5-571G-57MJ with an Nvidia 820M. I upgraded the BIOS to V1.32 and am having exactly the same problem. Were you able to troubleshoot or downgrade? I need a lot of help. Thank you!
Hi all
you can try to reduce the BIOS using a BIOS recovery process....but the threat of losing personal data
Hello Dudu2002, So how would this procedure? I formatted my HD yesterday morning. So I guess I do not have much to lose. Could you tell me how to proceed?
My settings are:
Acer Aspire E5-571G-57MJ
Motherboard: Acer - Model EA50_HB
BIOS: InsydeH2O V1.31 (Factory shipped with V1.26)
Processor: Intel I5 5500U 2.2Ghz
Memory RAM: 4GB DDR3
HD Capacity: 1024GB
Nvidia Gforce 820M 2GB
Thank you for your help! I am very desperate with this situation.
I can not play and Gforce is clocked locked at 720Mhz even without using the board.
There is anyone can unlock avanced settings and power option for this computer BIOS?
Because there is a whitelist in m-pcie port and i can't regnize my egpu and i can't set x2 retraining link on pcie port, i have already purchased egpu setup from Nando but i have to do everything from ThE beginning when i power off my laptop
ThE BIOS is: insydeh20 rev 3.7
Ram: 8gb
Hdd: 1 tb
Processor: Intel i7 2.0 Ghz turbo boost up to 3.1
Hi, I got it sorted today. It seems that this problem is due to windows 7. I formatted and installed windows 10 PRO in UEFI and the card came back up and running normally!
