I reinstalled Windows 7 when I upgraded like I usually do with major upgrades like this. Didn't have any problems before running my 2600k, but from what I've read the 2011 chipset causes a whole bunch of problems all over the board. Is there any reason BitDefender would cause problems on this new board by chance?
Ran Memtest86 before a while back with the usual 4 passes to make sure it was ok. Left it running and on the 5th pass I had 1 error, just kinda disregarded it at the time, guessing I shouldn't have. That's one of the reasons I posted the pictures of that RAM module being shifted.
I'll uninstall BitDefender to see if that helps, just not a fan of MSE because it got horrible review scores last time they ran them =/. Thanks for the help! Will report back here if they continue.
