Ive got a computer problem and thought this thr best place to ask. My computer haa been acting odd, shutting down if the case is jolted which often happens if accidently bump my desk. Now when hitting power button it tirns on for 3 seconds and immediately shuts off. Wierd thing is if I hold the mother board down it works as long as I hold it.
