my computer was working without any problem tiil today. I decided to replace the keyboard with another one.And it did not boot .During booting keyboard lights continously flashes and I hear some sounds from the computer but my screen keeps standing totally black.During booting I don’t hear any beeping and all of the lights on computer are on .What could be the reason ? Thanks for your interest and help.
