I might have a solution. Some background on my exact same issue:
Have an Alienware Aurora r1 with x58 chipset. Worked perfect. Installed an OCZ Vertex 3. Random freeze ups just like yours. I tried everything from A to Z mainly concentrating on the RST drivers. Nothing ever worked. Every day or so everything would just freeze up. Reboot and good to go. Next morning or after work, frozen. Figured just an issue between the x58 and the OCZ controller.
Bought an Intel 320 (my board is SataII max). Everything was perfect for the first few days and then guess what. Same issue.
I just watched your video and guess the first thing I saw? Identical G15 keyboard. I've seen some threads stating issues with the G15 and the Sata controller when using SSDs. Give a try using a different keyboard. I plan to do the same this weekend and see if that cures it. Maybe something with the keyboard drivrs controlling the keyboard LCD?
My only guess at the moment. Like I said, I'm in the same boat and I've tried EVERYTHING! I'm an A+ cert Network Admin as well, just pulling my hair over this one. Hopefully it's that simple.
