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 motherboard 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.
This, I used an old board and it didn’t work until I replaced the (button) battery . After that, you can troubleshoot the board adding components one by one and listening to the beeps. There’s a code. Left the GPU as last element and use the integrated one always until all is working. If a external GPU doesn’t work, it could be not enough power. If memory fails, beeps again, try to find a working one and go from there…
