Memory having issues

[cwyatt06]

Ok so here's my rig followed by issue

Asus Maximus V Extreme
Intel 3770k
Corsair Dominator Platinum 2x8Gb 2133mhz
Corsair ax860 PSU
XSPC Raystorm 760 Water Cooling
Nvidia 660ti
2 SSD
1 HDD
Windows 8.1

My build is 4 months old. Worked fine for 3 months then it started randomly restarting with a loss of power critical error. I RSA the PSU and got it changed out and the restarting continued. I tried reseatig the Memory and the problem went away for a week then started again. Now it will only work with only 1 stick of memory in the 4th slot otherwise it will show a error 55 on MOBO. Both sticks will work there.
Kinda at a loss and it's a annoying issue bc it's so intermittent.

Might loosen then snug down the CPU cooler, if too tight on a corner or side it can cause problems w/ the MC (memory controller) and miss a channel, clean the DRAM connectors, blow out the DRAM slots with compressed air.
