Graphic problems/WinUpdate Problem/Updating BIOS ---> XC-605-EB31

Hi everyone !

I have been Trying to contact support for the longest but for some reason, my SNID and S/N are never recognised...

Anyways,

I have a AXC-605-EB31 which at base was Windows 8, Intel Core i5 processor 4440, Intel HD Graphics, 1TB Hard Drive, DDR3 Memory.

As i booted it for the first time, There was an update right away to Windows 8.1. After an update to Win8.1 a few monts after i got my computer, one of my games started to bug out, and i heard it might have been caused by the game itself being too old for the intel card which was too powerfull for it. In the end, i left the game and never went back to it.I think i did something at the time, but i can't rememeber. I might have tried to downgrade it at some point.

As time went by, the Windows10 Update rolled by, so i signed in and got the update on Day 1.

I must mention that i got multiple graphic card crashes happening from time to time. But i was expecting a Win10 Update to fix the problem.

Later On, Minecraft, for some reason had problem loading textures and i still didn't know why. At the time, came to the Acer Website to try to get some support but couldn't get any (and i didn't know Community existed...) , so i went to Intel to try to fix the problem... to no avail. In the end, i decided to get myself a new graphics card (a Radeon HD 6450) to replace the current buggy one. It fixed the problem... but not the crashes.

and here comes the problems i have lately:

The Graphics Cards Keeps Crashing at least once a day,

The Graphics Cards Shows me a Stroboscope of light every time i try to update it to latest version,

Microsoft Update gives me a "Blank" Error message when trying to update latest Updates (i am stuck on Version 10240 )

When talking over in the Microsoft community, We came to the conclusion that i need to update all drivers (I did all of them, Manually, using the Exe in each pack, even the Intel Graph Card but i'm not sure it worked properly...) and Update my BIOS.

My Current BIOS Version is "P11-A0" while the latest is "P11-B4". I've been told to be extremely carfull with the update so i read the "Readme" inside the package... but still don't know what to do.

So, i would like a bit of support as to how i can update my BIOS, the questions i have being:

-What does it mean by "Booting to windows System"?

-Where is "BIOS Package"? The screenshot provided says "C:\D11\Normal\Win" but it's not making sense as i am thrown at "C:\Windows\System32". And i'm locked there as It told me to go and place the BIOSon a flash drive... which is  "E;\"

-Do you think i am on the Right track with what might cause the problem ?

Thanks for taking some time with me.
