Dear Team, 

I have a G9-791 with 32GB Onboard Ram, and Later on I installed 2 x 16GB Additional Crucial Rams by removing backpanel of the Laptop. Total memory was upgraded to 64GB and everything worked fine. 
My YouTube Videos started stuttering recently, and overall system felt lagging .. hence I wanted to update all my drivers and bios. 

I have updated my bios yesterday using the self update tool located https://www.acer.com/ac/en/US/content/support-product/6371?b=1&pn=NX.Q09EM.012
Which is the support page for my Model. 

After updating the Bios, which was V 1.11 (The Update went successfully, completed and the laptop shut down itself). 
I was unable to turn it on after the bios update. When I press the Power button, The Machine lights up, Fans starts, (Display remains blank) and after about 3 seconds everything switches off again. 
Did the Battery Pin reset, 5 Second, - tried several times, nothing helped. 

Finally, I removed the backpanel and removed both the Rams and tried booting it. It boot up fine and everything works.
System shows the installed 32GB Rams, and everything seems to work fine. 
 
Then I tried to Troubleshoot the issue as below ->

* Install one RAM on Bottom slot - Power on, No display - shuts down
* Install one RAM on top slot - Power on, No display - shuts down
* Install both RAM's - Power on, No display - shuts down
Removed both the rams again, and the system seems to work fine. 

What should I do ?
Is there a way to change some setting and make the device detect the additional Rams again?
Or Can I downgrade Bios? - If yes - How?
