Alienware x51 computer won't get past boot screen

I have had an x51 for two years now with no issues till last week. It first started with the computer randomly turning off with an error message of "hard disk drive not found". Today though I had the computer Windows update (Windows 10) which it froze on 99% for 5 hours until I turned it off. I turned it on and the computer gets to the spinning circle of dots then goes to a black screen and then back to the circle. When I entered Windows boot manager I received an error code of 0xc0000185. I can't find any of the disks that came with the computer.

Hi,

Did you enter the Windows Boot Manager by pressing the F12 key during boot? Try removing Hard Drive, doing a power drain and then installing the Hard Drive again. First remove your Hard Drive following the steps on this video. Once you remove the Hard Drive, press and hold the power button for 1 minute (do not connect anything yet). After doing this, connect everything again and turn on the system.

Hi,

Try running an ePSA/Diagnostic test on the system to check the main hardware components, click here to view a Dell article that explains how to run this test. Let us know if you receive any errors.
