Hello today i tried to clean up my pc and i got the problem i dealed with so many times but today i cant fix it. My PC works fine every FAN spins , LED light works but i dont get power into my USB-Monitor. As i told i had this problem many times but somehow i managed to fix it.
-Last time if im not mistaken power shut down while holding power On/Off button and Turning off the Power Cable helped me.
As always tried to google it and try to fix my problem.
- Replacing everything
- RAM places
- Trying other ports
- Did a other of things to since my english isnt that good i dont know to explain. Basicly did everything
But maybe i did smth wrong
Can it be Power Suply?

I would like some more ideas or fixes give what u got
Thank u very much

Whilst cleaning, did you use an ESD strap by any chance?

Well, you may have just introduced another problem to your machine!

Always use ESD precautions when handling Electrostatic sensitive devices!

If you are going to be taking you machine apart, you need to understand what can harm them!

If you are trying the RAM in other ports, it isn't going to work. PCs don't work that that!

Take out all of the RAM. Boot. Do you have any indication that the RAM is missing (beeping perhaps)? If not, then the Mother board is 99% certain fried! Di you build this PC yourself? If yes, did you attach the speaker (Piezo)?

It should be like this: (https://en.wikipedia.org/wiki/Piezoelectric_speaker

If you did not build the machine, it should beep if it was bad!

So get another USB monitor and see if the one you are using is fried! Do you have a friend with one? Does the monitor have an On Screen Menu? Meaning, can you control the brightness external form the PC controls? Is there a menu button on the monitor? If so, when you press it, does it display anything? If not, it is bad!
