I have researched and written this very carefully.
Perhaps AMD or someone would like to help nudge my pc toward working decently, despite AMD and Microsoft, by providing some solution or workaround that might be very obvious to you but that i am missing. That would be so appreciated.
The outdatedness of the AMD driver on my new pc seems to be the cause of the pc's extreme slowness, after many hours working on the pc with Microsoft.
But AMD seems to be preventing an update of that driver:
I want to use the Manually Select Your Driver tool at http://support.amd.com/en-us/download. But i can only do that if i simply have my pc's AMD graphics card's model name, which i have, and also the model number, e.g. 'M350' or similar alphanumeric string:
model name: The name is variously stated as 'AMD Radeon R7 Graphics Processor' and 'AMD Radeon R7 Graphics'.
model number: AMD reveals no number such as 'M350'. That's so even after i followed the detailed procedures in http://support.amd.com/en-us/kb-articles/Pages/HowtoidentifythemodelofanATIgraphicscard.aspx#DID -- that webpage leads to the result that the device is supposedly 'Audio Controller' vended by Intel, which is false. If you want the detail, that webpage sends me to the pc's Window's System Information, which gives the Device ID as 0x9874 (aka DEV_9874) and gives the model name/series, which is, again, 'AMD Radeon R7 Graphics Processor', without any 'M350' or similar model number.
Or, if this card has no model number beyond the 'R7 series' name, then AMD needs to add that quoted choice to the Manually Select Your Driver tool at http://support.amd.com/en-us/download (in its Step 3: Select Your Product) in order to allow that tool to work for this AMD-driven pc.
- The pc is an HP Envy x360 laptop pc (Model M6-ar004dx), with 8gb of RAM, running Windows 10, 64-bit.
- The AMD driver on the pc is Radeon Software Crimson Edition 16.6.
- The AMD driver-auto-detect tool at http://support.amd.com/en-us/download is also no help because it too has an error: it is falsely reporting that the pc already has the newest AMD driver, when my notes document that previously the driver date was a more-recent, specific date.
