Windows 10: Black screen with No Splash

So basically what I did was that I opened my whole pc and cleaned the dust and then I reassembled it back but now, whenever I press the power button I dont get the splash screen [Dell] and my screen only shows blinking white cursor. I cannot even access Bios.


My specs:

Dell Optiplex 755

4GB Ram

Geforce 210

E6550 Processor

:)

 

No splash screen at daily startup

Almost, it is an NP350VC5 (Black), it came with Windows 8 and the latest Intel Graphics Driver dates from 2015.
Further edit: seems I was wrong.
After a reboot, I now get a completely black screen, no Samsung splash screen or anything.
The steps I took before donot help anymore.
Where do I go from here?
