I have tried contacting Acer to get updates for this driver and the DMA Controller as below but as Acer have told me that they don't support my laptop which is a 2015 one I tried to update them manually but when I went to update from the "manufacturers" option under the PCI options when I clicked on Intel Celeron option under the manufacturers option I wasn't sure whether they were all for my Windows 64 system and a warning popped up telling me not to download unless I knew the source etc.
So I am wondering if anyone else has any ideas. This is a screen shot of the appropriate page:
Also is the System DMA Controller easy to update?
TIA🙂
