Strange Hardware Issue Preventing Windows booting.
Hope I could get some suggestions for a desktop I built 3 years ago that has been working flawlessly until a couple weeks ago running Windows 10 V 21H1. It has a Gigabyte X999 motherboard with four, 4 Gigabyte memory sticks for a total of 16Gig.
During the morning boot, the windows icon appears, but all disk activity stops and it just sits there forever. If I try to reboot, it does the same thing over and over. Never will boot, not from the internal HD, or USB or DVD sources.
So I started switching out a different video card - no help. Boot stops at the same point.
Next I removed the two of the four 4 Gig memory sticks that were in the last two memory slots and bingo - the PC started normally. Problem seemed to disappear. So I figured bad memory and ordered two new 4 gig memory sticks and put them back in the original slots. System acts normal for a few days, and then problem repeats.
I remove the two new memory sticks and problem goes away again. I wait a few days and when the problem repeats, I remove the same (new) memory sticks, reseat them, and it boots find for another few days. Switch around the memory sticks, same problem will eventually reoccur, and reseating the memory in the same to slots and it boots again for a few days. If I try rebooting without reseating the memory sticks in those slots it will never boot.
So I am thinking the motherboard has a problem with the two memory slots? Is my next step to replace the motherboard?
Advice please
