  1. Hi, What motherboard and power supply?
  2. Its a MSI Mpower, the PSU im not sure about, however, its a 520w, and i know it works,
  3. It might be due to change in GPU Voltage somehow (through the BIOS).
    So, check it also... And, set it to Auto...
  4. It might be a problem with the HDMI port. Does the card have a DVI port that you can test?
  5. Yes, that has been done
  6. What's the setting in BIOS for the Graphics (iGPU, PCI,...)?
  7. As Alexoiu is saying, have you in fact gone into the bios and turned the on board graphics chip set off and set the Pci-e slot to be the default primary video graphics output source ?
