Confusing Mobo/Ram/Game issue - can't figure out whats wrong

[Aimbit]

I am leaning towards the mobo having gone bad but here are the details....

 

1. Few weeks ago motherboard starts beeping with ram issue (no noticeable issues though, everything working fine)

2. two weeks after that, call of duty begins crashing 100% every time a few minutes after booting and joining a game

3. Tried playing CS:GO - no issues. Entire PC runs like normal, except COD

4. tried updating all drivers, system tests, ram tests, system restore, uninstall/reinstall everything (aside from windows) etc, etc nothing works.

5. remembered mobo beeping, maybe ram issue? Removed one stick of ram, leaving only slot 2

6. CoD works fine albeit with less performance

7. swapped ram sticks to test the other one, everything works fine

 

After that, I moved my ram from slot 2-4 to 1-3 and it worked ok for about a week, no motherboard beeping either, but now COD seems to have started crashing again at the same time.  I removed one stick, everything works fine again.

 

So I'm not sure what is at fault.. the RAM seems OK since the computer functions with either one installed by itself and ram tests came back without issues.  Is the mobo having ram issues so its causing cod to crash? I'd imagine CoD is more memory intensive than CS:GO so maybe its only surfacing then.

 

Just looking for some advice on what to replace basically...

Could be a board problem. How long you have it? Ask your seller for a board exchange.

I've had this board for years.. probably around the time the 6700K released.

 

I guess I will just buy a replacement board for now, I plan to upgrade in the future.

 

thanks
