Acer Aspire 6 with Optane memory going slow

Hi.
I bought my Acer Aspire 6 with Optane memory almost 2 years ago. I'm currently in France and a couple of months ago I had a problem with the computer so sent it to Acer France to repair. It came back fine but in French, and running very very slow. I called Acer France and they said that it was slow because it only has 4GB DDR4 memory. I told them it also had 16GB Optane memory and they hadn't a clue what I was talking about.
I called Acer UK to ask about the Optane driver and they told me to download the Optane driver from the Intel site. I have done this but I'm not sure that it's running.

My computer is still very slow: hanging up at times and I'll have to wait sometimes 15 minutes for it to get back to normal.
Can anyone help please? In the ABOUT on this computer it doesn't mention the Optane memory, but on the Device manager it's there.
Thanks.

First, F2 into the BIOS menu on startup. What is the SATA mode listed in the BIOS Information and/or Main tab? Also the full model number lister, eg A615-51 or 51G Phonephotos would help. Jack E/NJ

Hi Jack and thanks for the reply.
The SATA mode is RAID and the full model number is A615-51-51V1.
NB. On startup it now says that some network drives aren't accessible. When I click for more information it shows adst (//pxe) (X:) nb that should be 2 backslashes but I can't find the symbol on my keyboard. Also a drive picture with a large red cross on it.

Also, have you any idea how to change the computer language? I've managed to change Windows language and keyboard to English but on start-up it tells me in French AND English.

Many thanks.

As far as I can tell, no optane card is actually installed despite what you seem to see in DeviceManager. Go to the BIOS Advanced tab and set the SATA mode to ACHI. It may or may not boot since for some reason the machine was set up in RAID configuration. If it doesn't boot, I think the quickest and fastest remedy will be to re-install Win10 english version using Microsoft's USB media creation tool in plain vanilla BIOS ACHI SATA mode. The Toshiba HDD you have in there now has a decent internal RAM cache that should be reasonably fast all by itself without the RAID or optane complications. Jack E/NJ

Hi Jack and thanks for the reply. The SATA mode of is RST with Optane, which seems to me to be correct? Here's the photo of the setting. Also the message which comes up at the beginning about the network drives and which one. This may not be anything to do with speed, but have you a suggestion about this too please? Thank you.

The network drives is likely a wireless printer sdcard or usb drive that's either turned off or not detected at boot time before the wireless connection is fully made. Unrelated to your main issue.

The SATA mode should be changed to AHCI since an optane card is neither installed nor detected by the BIOS in its Information tab. Also the F12 boot menu option should be enabled. Then save settings and exit to see if the machine will still boot. If it does boot, it will probably also resolve the slowness issue.
