RE: Computer half turning off
For your mouse not being able to bring your PC out of standby do the following.
Right Click My Computer > Properties > Hardware > Device Manager > Mouse and Other pointing Devices > Right Click Mouse > Properties > Power Management > Check off Allow this device to bring computer out of standby.
For the other problem try this to see if your PC will blue screen afterwards.
Right Click My Computer > Advanced > Settings (For Startup and Recovery) > Uncheck Automatically Restart > Hit apply and so on.
