So here is my situation:
Yesterday I replaced the stock Intel cooler for my i7-870 with a water cooled system. After installing it, my computer would turn on and off rapidly, so I immediately removed the power. Come to find out, the motherboard wasn't accepting the fans in one of its fan power slots. After moving the radiator fan to a different power slot, my computer booted fine.
About an hour after messing with my computer, I noticed a performance dropped and found that my computer only was reading 4gb of my 8gb of memory. After some troubleshooting, I essentially switched the sticks with each other, and my computer now reads all 8gb with only 4gb usuable.
Here is a picture for reference:
Here are my system specs if needed:

Kingston 8gb (2x4gb) DDR3
