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.
Okay, most absolute basic troubleshoot check: is there an on/off switch on the power supply that might be off?
Yes, there is one on the back of the case that I switched on.
If it were off, I would assume there wouldn’t be anything to power that tiny light near the Graphic card connector.
Edit… not an assumption anymore. If you turn the switch off, the light turns off.
