my computer was turned off and when i went to press the power button i got a little shock and now it doesnt turn on. however, if i turn off the power supply until the green light on the mobo goes out then turn the psu back on, all the lights come on and fans start spinning but will shut off after about 3 seconds. i think that is a normal thing though and when you press the power button on th case it should turn on, but doesnt. does this mean the power button on the case doesnt work or my mobo is fried or what?
