Initial suspicion,
Inadequate PSU.

comp was supposed to have been shipped with a plastic bevel over the pci e slot stating only pcie x1 was compatable, it did not so the pcie x16 fit fine and i assumed it was compatable. time and money down the drain due to a simple missed plastic bevel and incorrect specs from the comps vendor websight.
