"This PC has unsupported hardware" error message

On my Lenovo b570 laptop, I am randomly getting popups during games with "This PC has unsupported hardware" messages.

Which nothing could be further from the truth. This laptop originally came preinstalled with Windows 7 and it never gave that error message with the old now defunct hard drive. And my new hard drive came from another Windows 7 computer so it is not the hard drive either. It says in the error message something about the processor but considering that Windows 7 came preinstalled on this machine, that is false.

In fact, Lenovo has drivers for Windows 7 64-bit only. No Windows Vista or earlier, and no Windows 8 or 10. This is a Windows 7 designed PC.

But I still get the error message

Open Control Panel & select Device Manager & see if there are any yellow exclamation marks alongside any item. Get back to us if there are any.

When you say the Hard Drive came from another Windows 7 computer, did you do a fresh install of Windows 7, or are you using it without a fresh install. If that is the case there would probably have been some hardware on the old computer that is not on your computer & it is looking for that hardware & hence the message.

It is a clean install. I used Gparted to wipe the drive first.

There isn't now after I restarted the computer. I don't know if there were before I restarted my computer.

no exclamation points anywhere and obviously MS is mistaking because Lenovo doesn't support Windows 10 on this machine

That is the message microsoft has been giving to users (like me) who are using a Kaby Lake cpu on windows 7. But the laptop you are on I believe uses a Sandy Bridge cpu, so its weird you are getting that message. Suggest you run intel driver detect to update your drivers. If you indeed are running a Kaby Lake cpu, you're going to keep getting that message, but you can ignore it.

Intel® Driver Update Utility

I don't know what a "Sandy Bridge" CPU is. Mine is Intel. I've only heard of Intel, AMD, and Nvidia. Never heard of Sandy Bridge but this is the specs.
