Motherboard Replacement HELP

[Uni15]

I'm stuck right now. I can't do ANYTHING. My computer will randomly turn off in about 1 minute after I push the power button...

I fixed it and know what to do next. Can you delete this thread please??

Are you trying to boot to Windows or OS X. I'm confused.

oops... nvm
didn't mean to reply... can't delete...
