Hi, I have a Shuttle SG33G5M and just added a PCI graphic card (HD 5450). I am not able to use the PCIe as I already have a raid controller sitting on it. The jumper is set to use PCIe. Now, after I added the graphic card, the PC does not boot anymore. It does not even seem to initialize as it does not even get as far as calculating the memory. It just beeps, turns the fan, and after 5 seconds it beeps again, turns the fan, ... and so on. When I remove the graphic card, all is fine again. What can that be related to? The power supply is 250w only but should be enough for a PCI card, isnt it? Does anyone have any idea?
