Dell Inspiron 5010 Stalls at win7 starting windows screen

I have a customer laptop Dell Inspiron 5010. When Starting up it stalls at the starting windows screen and there is a varigated color bar approx 1/4 inch wide at the top of the LCD it does not show the loading bar. I did a factory recovery and the same thing. I ran Eurosofts PC check and it shows no problemas with the video card, hard drive, motherboard nor memory. Anyone have any suggestions.

You should run the Dell diagnostics from a Dell Diagnostic CD.

is the barr still showing when booted from the cd?   then you have a bad video card, or screen

None of the photos in ur suggestion appear to be the same as my problem right now I am running the Dell Diags and the screen looks perfectly fine. Good color nice and bright and no signs of any problems.  I at first thought video card or LCD screen. I will repost after I have completed the Dell Diag. test.

if the dell diag is ok, it is probably a software problem
you can test if it is ok in safe mode, or try the latest known good
you can also post a picture, so we can see it

The dell diag was fine no problems. The only software on the laptop is the original factory restore which I did from the restore partition.I have included a couple of photos on where I tried to enter safe mode and one where I tried to just start normally. Normal Start Safe Mode

i don't see anything wrong ? maybe the color?
is it the same on an external screen ?

This is as far as it will boot, the top is normal startup and the bottom pic is in safe mode even after I did a factory restore. There is a multi colored line near the top of the screen and yes it is the same on an external screen.

I believe that nobus is correct in his assumption that the hard drive is defective even though I was unable to confirm this and the laptop I found out is still under warranty. So I told owner to send it back to Dell for repairs.
