Go to Advanced System Settings (you can find it by searching in Start menu), go to Advanced > Performance/Settings > Performance Options/Advanced > Virtual Memory/Change > No Paging File > Set.
This will null the paging. See if that fixes it. If it's alright afterwards, you can set it back to system managed size.
If you have 16GB of RAM or more, though, it's probably best to just have it off. Probably not nice to have Windows poking around and constantly writing to your SSD, anyways.
Either way, Samsung recommends having virtual memory enabled on the drive with 200mb initial and 2gb max.
