Z420
Microsoft Windows 7 (64-bit)

Hello. On 14th January, I decided to finally use a Microsoft free upgrade to Windows 10 ... but oh boy, the problems with and after that! <sigh> Everything seemed to go well but after installation, when the computer restarted, as soon as it past the Win10 logo, the monitor (AOC v22) went completely black and I couldn't see a thing! I have absolutely no idea why and there's nothing wrong with the monitor (obviously it's still working since I re-installed Win7 Pro 64 bit) so my question is, is my desktop (product # WM520 ET) compatible with Win10 (ie is it capable of running it?) and, if so, any idea why I might have had such a display problem? Any help/advice/opihions very much appreciated.

 

Oh I forgot to mention the error message I got at the time was "Input not support" ... the fact it should be supported, we'll let slide. lol

is your z420 win 10 compatible?,...no it's not all of the successful posts on this forum and the internet saying successful installs of win 10 are obviously wrong because your having a problem right?

 

you have a video display issue, not a windows 10 issue per say

 

did you do a win 7 to 10 upgrade? if so i suspect that your current windows 7 video settings are wrong and when win 10 tries to import them it is unable to

 

set your video settings under win 7 back to defaults (no custom video settings) and remove any 3rd party video tweak applications

 

furthermore you might want to set win 7 to 1024x768 at 60Hz before trying to update

 

hint,  dl the latest win 10 usb key installer (16gb key needed) and FROM WITHIN WIN 7 go to the usb key and run setup or install to start the win 10 upgrade doing it this way will grant you a free digital win 10 pro license that is tied to your motherboard

Thank you. Yes I tend to agree it's more likely to be a video display problem. Yes it was a Win 7 to 10 upgrade, you're right. Just surprised me you didn't get the option to revert or keep the settings during install like you get when changing screen resolution.

 

For the time being I'm sticking with Win 7 Pro. I've purchased an annual subscription to BitDefender Internet Security so hopefully that will cover any future security issues there may be but certainly if I do try the upgrade back to Win 10, I'll bear in mind what you said.

 

Thanks, Nick

You shouldn't have an issue running 10, but if you're sticking to 7 and won't be doing any installing/uninstalling, reboot restorerx and timefreez are great to just lock down your win7 install completely.

Thanks again for the tips, Samir. To be honest, I've never heard of Restorex or timefreez (timefreeze?) and no idea what they do but thankfully I know a man who does ... his name's Mr Google. lol
