Black screen with flashing white bar

I have a Dell Inspiron 7559 and I'm trying to get to the first setup of El Capitan. I installed it just fine but when it came to booting to the SSD, the Verbose boot stuff would do its thing just fine and then the screen would go black and then flash a white bar on the top left of the screen once with 5-10 second intervals. Sometimes, it would flash one line of Verbose code on the top and then the white bar would reappear. I tried reinstalling El Capitan 3 times and it does the same thing. I am stuck and need to fix this issue. Here are my specs

 

CPU: i7 6700HQ

 

Ram: 8gb ddr3

 

GPU: GTX 960m (Intel HD530 for OSX)

 

SSD: 250gb Samsung 850 EVO

 

HHD: Seagate 1TB SSHD
