Alienware X51 turns on with no display

Hello,

      I've had my PC since 2013 and the HDD failed in 2015 (fixed). Last year around this time it starting it's current problem where the PC will turn on though I don't get a display nor do I hear any sounds. I was to busy until today to tinker with it at all. I'm using DVI for display, below are steps I've taken to troubleshoot the problem. Thanks for reading and any help you can provide.

Tried:

*Other DVI output from PC

*Using HDMI

*Using built in HDMI (not on graphics card)

*Hooked a laptop to display through HDMI and VGA (both worked on different computer)

*Holding F2 during boot

Display:

HP2711x

VGA, HDMI and DVI ports in back

Display worked with this PC from 2013-2016
