I have been helping a friend that has a HP Pavilion machine with 6 gigs of Ram and a dual core processor. When I first turn on the machine the monitor will display no signal and go to sleep.
If I restart the computer it will do the same thing again and usually after I restart the machine several times it will start and work perfectly. I don't understand why.
I have changed the cords and checked to make sure the connections are seated properly. I have looked and the VGA connector is on the motherboard. Could it be that the connector is going bad and needs to have a VGA PCIe card put in one of the slots. I don't want to have my friend stand the expense of a card especially when it does it works fine until the next time I start the machine.
I ran through the HP Diagnostic Tests and none show any problems. Any additional ideas would sure be appreciated.
