Hi, my pc was running fine for a couple of months and yesterday my daughter knocked down pc (pc was on the floor it didn't fell from desk or any height just knocked on the side) and i couldn't get it to boot. I tried to take out 1 ram stick and it booted normally. So after couple of minutes swapping ram slots and trying different combinations i saw that all ram slots are working and pc can boot with 16 gigs of ram but only in single channel. When i try to put ram on 1 and 3 or 2 and 4 it wont boot. Any help ?

I had the same issue when i updated my bios and changed my processor kinda.
So what fixed it is, rubbing the contact pins on the ram with alcohol to clean any oil or something on them.
Not sure if it will work or not but you could try.
Or your RAM got damaged when it fall out of the slot when your daughter kicked the computer.
