So since installing the SSD above I've been having various problems. I cloned the HDD I was using for Windows and League of Legends to the SSD using Macrium Reflect. And the SSD is now set to be the first loaded.
Since then I've been having the following problems...
USB ports randomly stopping and starting. Happened to my Linksys receiver first, then my mouse port. No others have had the problem yet.
Random crashes. I went afk to make dinner and came back to a black screen. The monitor wasn't off... just all black. Tried unplugging and plugging it back in; stayed the same. Was playing Diablo 3 and FPS dropped to almost 0 and lagged some, then it said I was disconnected and I tried to click okay, but it was frozen... mouse still moved but couldn't alt tab to desktop or alt+ctrl+del. Then screen went black after a minute or so and stayed that way until I powered down the computer.

Anyone have any idea what could be going on?

i'd try reinstalling all your drivers.

If that doesn't work, do a fresh install. Sounds like a perfect example of a bad clone.

Thanks for the replies. Will get it done today.

Wait, why do you have 8GB of single channel? You only running one stick?

 

[Buriedfire]

No. Running two 4GB sticks of Ballistix Sport.

 

[PP Mguire]

Do you have the sticks staggered? That should be dual channel.

I had a stick in the wrong place lol. Fixed now
