My computer, Compaq Presario, keeps shutting part way off like it does when you put in standby but then it won't wake up. I had the same problem about about a week and a half ago and it wouldn't stay on long enough to boot up. I finally took the front panel off and wiggled the cords to the switch a little bit and it worked fine so I thought it was something on the panel holding the switch in too long. I never put the front panel back on and it worked fine except for a time or two until a couple of days ago. I took the switch out and wiggled the cord and made sure they were plugged in tight but it won't do more than switch on then it shuts part way off. Your help would be greatly appreciated!
