Wii Emulator Crashing my new PC

[BabyBasset]

I havent played Splinter Cell Blacklist for a while but when I did I played it no problem on medium or high settings, Mafia 2 on high settings too, and GTA 4. It never crashed. Im puzzled.

Anyone has more ideas? I appreciate all the help

Also, I get this error when my PC starts up and I dont know how to fix it (attach)

Also, Is there any way to monitor PC with some program so I could know detailes of what happened immediately before shut-down?
