Do you have video card installed in addition to your onboard video? It sounds like you have your monitor connected to the onboard when it should be connected to the video card.

 

i was able to get into safe mode and restore to a different point .that fixed it.sorry for the trouble dont know why i didnt think of that before.thanks for the help and quick responses.kildar and i am outta here..........

 

I wonder if your video driver got corrupt during the swap-ex. Glad you got it fixed.
