-So I had an issue with my PC, "personalised settings (not responding)".
I found out its to do with my RAM and that updating "motherboard BIOS (update) changes how the hardware and memory addressing space is accessed, this has a big influence on Windows".

-I spoke to MSI forums and the person said I had to "update (flash) BIOS for my Motherboard to fully support the Windows 8/10 UEFI features" . But also "for UEFI to work you must do a clean install and the BIOS options must be set to have Windows 8 mode / Windows 10 enabled" ... as apparently now my current W/10 was installed in 'Legacy' mode, which UEFI mode does not support..?

You can read more about what he says here> https://forum-en.msi.com/index.php?topic=290365.new;topicseen#new He is called 'electrostingz' so you can just read his comments.

I just wanted to get 2nd opinion and confirm on other forums, such as here, that I would need to do this; Once I flash update my BIOS, I need to then clean reinstall Windows and all my games/apps etc

I have been instructed to:

1-Flash BIOS
2-Check BIOS settings, enable Windows 8/10, disable Windows 7.
3-Save&Exit
4-Enter BIOS check Boot options, are they showing UEFI
5-Boot from Install device, DVD or flash drive. (I don't think your current Windows will boot)

My Motherboard: B75MA-E33. I currently have v1.1 and I need to upgrade to 1.7

Thank You
 
UEFI is worth the change, I'm not sure if there is a way for you to change without reinstalling. Try overriding system, you might keep all games, data going to windows.old

Bios update is a risk as always. Prepare life usb ubuntu or second PC just in case.
 


Why is BIOS update a risk? I presumed everyone does it once in a while?

Also what is life usb ubuntu? I have been told just to use Microsoft link to obtain the files for bootable usb download.

And I dont have a spare PC sorry
