After cleaning with a microfiber cloth, I put my PC back expecting it to work once again, especially since previously the computer was outputting sound and video flawlessly.

Now my computer will not output any video (perhaps sound) even when I changed the monitor, from DVI-I, to HDMI, to HDMI TV.

I will post computer details soon, but is there any common tips that can help me?

Alright, thank you. The problems have been fixed. It seems that the power supply and power outlet have been the issue. They had a weak connection that resulted in the computer not displaying anything. I tested it out using a direct power outlet instead of the power strip I had plugged it into. Fortunately, I got it working on both the power strip and the direct power outlet. Thank you.
