Thanks !
There are currently showing 228 plus 46 optionals showing. So far I have de-selected nearly all of them and tried to download just a few.
It sort of worked, but the .net frame work ones failed.
Originally it was 243 important updates, so at least I have installed some of them.
I did try updating to Win 10 but that failed trying to get updates, so I just had to cancel it after about 20 mins.
Tomorrow I shall have another go, and de-select the majority to try and install them in small amounts, but I am not holding my breath.
I had absolutely no problems at all when I built my last machine based on an i7 920, on an Gigabyte EX58 Extreme flagship board, and the BIOS was a darned sight easier to navigate than this shiny new uefi BIOS !
I have the latest F7 BIOS updated from the original.
But although everything works just fine (I have Win 7 mounted on the Samsung 950 Nvme 256GB, and also cloned a copy of it onto a Samsung EVO 850 250GB drive, so that once I can succeed on one, then I can clone it over for safety, like wot I always does.
It really seems to be hard work to get this PC running as it should, and almost tempted to call in a PC fix it matey to help me out, and hoping the money will be well spent.
I only had to do that back when I first started with a PC on Win98, when I didn't know how to install an OS, and managed building PC's just fine ever since.............until now.
The expectations of building a new PC has now rather soured as I can't get it running properly....*sad face.
P.S. It hurts a bit because I always buy Gigabyte motherboards....
But thank you all for helpful replies.
