Question Computer powers on but no display

Feb 18, 2019
(I dont know if this is the right place to put this, though i do believe it is a motherboard problem. Im new here lol)

Hello! I have been having a problem recently and im out of ideas on what to do. I am fairly familiar with computers so ive tried basic stuff and more trying to fix it.

I have a Lenovo Thinkcentre m92p (nothing good lol)
Core i3 2130
8gb ddr3
Hd 7750 (2gb ddr3)
2 120 gig ssds
1 500 gb hard disk
Windows 10
Windows 7
Ubuntu 18.04.2 lts
(One on each drive)

I was installing Ubuntu 18.04.2 LTS and after i was done i went into bios to change the boot order, after i completed changing it. The computer restarted like normal, but when it came back on. It showed nothing. I tried changing monitors, cables, graphics cards and nothing showed.

Though all the hardware turns on, but i did notice that the keyboard lights were delayed highly when i clicked the respective button they belong too

(Like if i press caps lock it would take like 10-15 seconds for it to switch)
I also see that sometimes when i turn it on it shuts off for a second and restarts

Any help would be awesome. I kinda have some important work on that computer and i really need to get it working as soon as possible.

Thank you! Have a nice day
