Thanks everyone for helping . I suspect that the motherboard does not supply adequate power to the PCIe slot . So . I ordered a new motherboard and case . My plan is to strip the processor , RAM , PSU HD etc and put these into an new case . If anyone is interested in the outcome i ' ll confirm that this fixes the problem and that the dell MBs have insufficient power to the PCIe slots for upgrading . For those of you who frequently help people on this sub and maybe help with building budget gaming rigs , you may want to warn against these dell ' business class ' MBs <| sep |> u appear to have a plethora of items in your trousers and , sir , if i may be so bold i daresay several of them are phallic in form <| sep |> They neglect the fact that her party has been caught destroying votes for trump . The difference is easily explained by her lack of desire to investigate as it would expose her involvement . Trump probably won by a much larger margin than was reported since she manipulated the ballots .
