Computer locking up when stressed.

This is not actually solved I just suck at life, and clicked best answer by accident.

My computer has been locking up recently. It seems fine until I start to put strain onto the system. This is usually done by me playing games. At first I thought it was heat and noticed my processor getting up there in temp. I went out and bought a new case and a new liquid cooling system (Something that needed to be done anyway). As I monitored over the next few days the freezing didn't stop, but my temperatures were a lot better. I did a complete reinstall of windows onto my HDD's to make sure it wasn't a driver. I did HDD's checks and nothing showed up. My next step was checking the ram. After running for 8 hours on each stick, then together, nothing showed up as an issue. I pulled out each piece to test everything, but like I said it only happens when I seem to put strain on the system. I tested both my graphics cards and I thought one was causing the issue, but it freezes on both. At this point I am at a lose as to what it could be. My thought is it might be the motherboard, but I am not sure. So I ask to you all, why is my computer locking up?
