G_Wizz said:I had the same problem with a DQ6, it would boot every time with a PCI graphics card, soon as I put the PCIE card back in it would go into the endless booting loop again. If you could get a PCI card you should be able to boot up then at least you would be able to flash the bios, if its still the same after a bios flash ask for an RMA.
I'm sure I have a Matrox PCI card at work rotting in a drawer - but I won't be going into the office till next week, could have lent it to the OP as I also live in London.
