hMm..my computer hates being turned off. it makes a non-stop beeping noise and fu..uh..messes up. the way i fix that is...

step 1. cry
step 2. unplug the power supply from the computer, not the wall plug or what have u
step 3. wait 20 seconds
step 4. plug it back in and turn the power on
step 5. cry again for good measure.

i dont know if that will help you, but it's like a 30 second thing you could try. be sure not to get any bodily fluids near the electrical sockets!
