[Resolved!]

I traded my cousin some really expensive RAM that I happened accross for his old desktop, that he put his graphics card into that he swapped from his newer computer. If I plug the desktop into the wall and try to turn it on nothing happens. If I open it up I can see that the where the wire from the power supply plugs into the graphics card there Is a little light on. So clearly some power is getting somewhere…

How do I go about trouble shooting this, and what tools do I need? I assume at minimum a multi meter? Not really sure what to do, it’s been decades the last time I built a computer.

Board says “Asrock H110M-HDS”

Edit: Attached a Pic and noticed the light is actually on the graphics card, not motherboard. Added addtl info.

Update: So now all of the sudden the fan spins. I am at a loss as to why it spins now, as I haven’t actually really done anything. I ordered a speaker for the mobo, so waiting for that.

Final update: It works! I apparently had either a bad monitor or bad display port cable. But using another monitor with DVI I was able to finally get it to fully boot!

I am not sure what got the fans to eventually work, maybe just a cable was jostled.

I really appreciate all the advice! I definitely know a lot more and feel better equipped to do things with it now.

      ? Remember my knowledge is basic.

      It doesn’t seem to turn on at all, there is no workable video output.

          Nope, nothing. The light on the case button doesn’t activate, there are no noises or beeping, the fans don’t spin. The only sign of electricity at all is a small light where it connects to the graphics card.

        POST means Power On Self-Test. All motherboards will run some diagnostics and detect basic problems (e.g. missing RAM, no boot media).

        If the motherboard beeps, you can look up the motherboard and see what the number of beeps means.

        So the circle is where a little speaker should be attached:

        Sometimes these come with the case, but in your case not apparently or the PC guy would have attached it. You can buy these pretty cheap (one or two bucks) and they look like this:

        When you have one attached and start the PC the mainboard will run some tests, and if it detects a problem there will be a pattern of beeps coming out of the speaker. You can look up what this pattern means in the handbook somebody linked above.
