I have an IBM Thinkpad T30 that wouldn’t take. I, too, have an old Acer that it brought back from death. I use it as a terminal interface for a Cisco networking lab.
Yeah, in my case it was because I use a add on video card...Nvidia, that I use for two big VGA monitors..
It kept crashing....(the new blue screen actually has a frowny face on it) and the crash linked the video driver package.
I had to force the machine to accept the old one that was not rewritten for 10. I put up with a number of warnings that the driver needs updating...but I can deal with that. I think it’s just a bug associated with my original motherboard built-in video...The driver tries to default to something it sees....and that screws up my Nvidia card..
I kinda doubt it will get fixed....it probably does not show up on anything but this motherboard and combination.
My permanent fix would be to purchase a new card, most likely..
LOL....You got me thinking with your remark about your IBM issue....
Does it perchance use a intel based video driver..?
I actually may have created this problem myself by deleting the intel drivers years ago when I added the first Nvidia addon card (upgraded since)..It’s easy enough to test..I may do it later and load the original drivers, allow the Nvidia card to update to a win 10 driver and see if it fixes the problem....I can always just roll it back..
