EVGA GTX 660 superclocked installation issue

[matt0722]

I recently purchased a refurb Lenovo k450 with an i7 16gb of RAM and a weak psu (directly from Lenovo though). I decided to upgrade to a better graphics card (from the on board video) and I bought a corsair CX750M psu and an EVGA GTX 660 superclocked. The psu seems to work great but when I install the GPU and plug in the correct video cable and have the BIOS set to auto (which selects PCI E first) and boot up the screen remains black. no beeps or anything. Just nothing. the graphics card receives power as the fan begins to spin but that's it. Any help would be great. Thank you

I hope its not that something is wrong with my motherboard or PCI E slot...

Do you have another card to test with? On-board video?

I don't have an extra card and I meant the integrated graphics card.

I presume you didn't forget to plug in the PCIe aux 6 pin cable?
What is the motherboard make/model in that Lenovo?
