Question Computer is not outputting video after cleaning

[Scaxer]

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?

Please post your entire system spec first, including PSU make and model.

Do you have integrated graphics to test on?
I suspect Static Discharge could be a problem with a Microfiber cloth as it could generate a lot of static.

If you have a discrete graphics card installed, I'd remove it and make sure the expansion slot is clear of dust and/or debris using a can of compressed air.

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.
