X51 R2 stuck in a boot loop help!

hi, so I got my Alienware x51 R2 in November of 2014, and ever since I got it it has been good. I had a similar issue when I updated to windows 8.1, but anyways, last night I decided to upgrade to windows 10, it was going smooth until around 33%, when it would off and on go from a black screen, to the percentage screen. eventually it went black for a while, and I just let it be because I didn't want to bug, so I left it and eventually my moniter shut off. so I restarted, and surfed the Internet for the black screen cures. I tried everything, I only have one monitor, so I eventually said it and factory restored. so I went to bed, and woke up to it STILL being stuck at 2%! so I got angry, and reset it! and now ever since, I will turn it on, it will go to the Alienware logo, load, do the beep, then the bar at the bottom will disappear so it's just the logo for a minute, then that will disappear, and repeat! I let it sit for half hour, and it did that for half hour! just constantly rebooting itself ! I have tried almost everything, so I am praying someone can identify my issue, because it's my only day off from work and it stinks how I have to spend it like this :( hope to hear a response soon.
