I have an Acer Aspire TC-120-UC22. I recently decided to buy an identical stick of 4GB in order to upgrade from 4 gigs to 8. When I installed it, my computer didn't recognize that it was there. When I tried to problem solve, I learned that both stick worked in either of the two blue slots but didn't in either black spot (meaning that I have four slots in total). I then downloaded CPU-Z to see what it would say about my RAM. when I read some articles, they said to check if your BIOS version is up to date. I checked and mine was over three years old. I went to the Acer website and downloaded the new version they had. I then proceeded to follow the instructions on the PDF document. When I started trying to boot the Flash drive, my computer just boot up normally. At this point, I don't know what to do. Any help is appreciated.

Acer website where I got the BIOS:

The Stick on top the foil is the new one, the close up stick is the old one, and the last image is after the install.

Thanks for the details!

Something is not quite right here. With the flash drive installed, the system should boot from the flash drive first. If it is not (as it seems), the flash drive might not be (made) "bootable"(?)

Boot into Windows using the old memory only.

Download the BIOS file (P11.A4) and PDF instructions, and save the extracted contents from this zip file.

Follow the downloaded and extracted PDF instructions to update the BIOS. It doesn't require a bootable USB drive for this process, just click on the Flash.bat file within the WIN directory to run the BIOS update process.

After updating BIOS and re-starting etc as per PDF instructions, try the new memory again. But, again, note that individual memory modules may not be...

Boot into (original) BIOS, and change the boot priority settings so that the system should boot from the USB port/drive first (then second boot option for CD/DVD if have this option; and finally third boot option via HDD/SSD). Save, exit and reboot with USB flash drive.

Flash latest BIOS following the documented procedure.

Clear CMOS with both modules installed in blue slots.

Note that even though both modules are the same part number, they may not necessarily be compatible with each other due to module characteristic variations.

I tried what you said but either it didn't work or I did something wrong.

Here is a video showing what I did: https://youtu.be/xZlkqZsaJsE

Thanks for taking the time to make a video, but as I'm on a slow dial-up connection (see my signature), I can't view most videos on YouTube and elsewhere. Sorry.

If you could describe in words what was done, that would help (me). Otherwise, maybe someone else who can view online videos can comment(?)

Thank you for responding so quickly
The first thing I did was select all of the settings for boot priority as you suggested.
For #1 I had [removable device]
#2 was [P1: HL-DT-ST DVDRAM] which I just assumed was my DVD rom
#3 [Windows Boot Manager]
and #4 [LAN]

Then I saved and pressed F12 on restart to select the location for my computer to boot. I selected "TOSHIBA Boot Manager" from the blue menu and pressed enter. After a minute of flashing a black screen, it just started to boot as normal. Then I tried restarting the computer without opening any menus. Still nothing. Did I select something incorrectly?
