I just got this new HDD because my old one died and I finally finished installing the OS and all my programs on it. My computer will randomly slow down A LOT. I'll be in a game, and suddenly it will be maybe 5 FPS sometimes. Everything but the mouse on my computer will be extremely slow, even the little click and drag boxes you make on the desktop will be super laggy. I check my temps and nothing is going over 60C. All my drivers are updated. After a few minutes it will go away. I can't figure out what causes this, but it happens somewhat rarely. It usually starts after I open a program or game. This didn't happen on my old hard drive. Any ideas?

Does seem odd, but I think on rare occasions, even the colors can be misleading on which channel is which, depending on board. I worked on a Gateway or HP a few years back that unless the RAM sticks were in 2 specific slots, the system would hardlock with graphic corruption. It had onboard video and I thought board was bad. Odd thing was if you used the slots the manual recommended for two sticks, it caused the problem. Using "wrong" slots worked fine.
Has anything else changed other than your new HDD? Have you installed the latest chipset drivers? Have you tried running a benchmark of some sort to check the transfer rates on your new HDD. I've replaced a bad HDD in the past working on a PC where technically it worked, but the transfer rate was avg. something like 5MB/s.

I didn't think this would make a difference, but when installing the new drive I also moved one of my RAM sticks over because I heard you're supposed to put them in every other slot. I moved it back and I haven't had the problem yet, but I'll post here again if it happens.
 
RAM slots depends on motherboard design. Usually for the standard dual channel mode, the sticks are one space apart and color coded. However, some boards are with sticks next to eachother. Generally, if in the wrong configuration, you cut your memory bandwidth in half, as you would be in single channel mode. Some motherboards can have problems running this way with two sticks.

The weird thing is mine go black, gray, black, gray, so putting them in every other slot shouldn't have caused an issue. But I haven't run into the problem since I put the stick back.
