audio out/display problem

I have a standard ASUS MB with on board sound/display cards.
Recently on boot, my lcd display goes all psycadellic. long coloured vertical lines appear on screen which change when windows is booting.
At first I thought it was a bad connection/cable between the comp and lcd display. This problem only happens occasionally.
The really odd part is that i've found if i wiggle my speaker jack at the back of the comp, the problem goes away!

Any ideas?
It's rather annoying.

OH, if i pull the jack out I lose all display. Put it back in, no problem
hmmmm? odd, try uninstalling the soundcard and removing the card physically and putting it in another PCI slot.

- this is where you say it's onboard sound ?
personal memo -read the Queation hippy
Check all items are seated correctly as wiggling may suggest something is loose

I think your motherboard is broken - this is not normal behavior and indicates an internal short of some kind.  I wouls advise you to replace the motherboard as soon as possible, especially if you have important data on the drive.

There are no plug in cards. its all part of the mb.
it's now started when i wiggle the lan cable!
Have you checked all the PCI/AGP cards are seated and held in with screws to the case. Also is your mobo loose -- check the board doesnt move on its backplane. Beond this just generally check everything is tight....... and fergawdsake -

Stop wiggling stuff :-)
