Windows 7: Computer randomly turns off (no reboot, no error)

Windows 7 Ultimate 64 Bit
Computer randomly turns off (no reboot, no error)

My computer will randomly turn off. Only if I am using it. I can turn it on and it will sit forever, but if I use it.. Boom. Shuts completely off with no warning, no error, nothing. I need to power it back on by pressing the power button. I went to CMOS and turned on restart on system failure and it does not restart. Don't think it's running hot.. at least, my gcard is only doing 48 C which is low. Idk if it's a software issue or hardware?

I ran a scan of my computer using ESET NOD32 Smart Security = nothing found.
I will attach dxdiag. I cleaned my PC inside the best I know how.. >.<
