The PC does not turn on after cleaning, the reason?

Question

Computers

The PC does not turn on after cleaning, the indicator is on, I didn’t take anything out, only the vidyuhi and put it back, I decided to turn on the PC later, but it doesn’t respond to the button at all, only the indicator is on, what could be the problem?

Answer 1

Violation of contacts in the video card connector (but this is not accurate).

Answer 2

Wait

Answer 3

If this happens after dusting, then you may have damaged the contact that starts the computer. And if the indicator from the motherboard does not light up, then it is possible that that round battery is dead or the power wire is broken. Need more details to give a more accurate answer.

Answer 4

The indicator is on, I think my power supply has burned out, tomorrow I'll go to the diagnostics and tell you the answer

Answer 5

Try to connect through the built-in graphics (if there is one, to check if there is a problem in the vidyuhi)
Since in the computer, as I understand it, only it was taken out and cleaned.
Or maybe you just lost the connector for the monitor on your monitor. The monitor is looking for a signal from HDMI, and you are on a display port or otherwise.
MB in general, you used a brush that has current conductivity and something is shorted. They cut down the computer, but did not turn off the power supply during cleaning.
It is also possible, depending on the antiquity of the device, that the computers do not want to turn on without a connected mouse and keyboard.
