hi, I have a shuttle computer, I am having problems with the grapthics, I have tried onboard grapthics, and the PCI-E card. The monitor flashs when I plug up the monitor too it. I have allready tried the trick where you turn the shuttle on and turn it back off again, and remove the power cable as you got to turn it on and leave it off for 30 seconds, but then it still wont respond.
