My HP Compaq dx2310 microtower isn't able to boot, it has no signs of receiving power.  no lights on the back/front, fan doesn't spin. I checked if the surge protector is giving power and tested it. It did. Same thing on the wall outlet, it still has power. There are no loose connections, so it must be the power supply is dead. How do i trouble shoot if the power supply is causing the problem or a different part of the cpu?

Hello a5tech,

 

You have more or less confirmed for yourself that it is the PSU that has failed but we can suggest a basic PSU test for you to do but only if you are confident enough to open up  the computer, post back and let us know and one of us will post the steps for you.

have you unplugged the power cord, then tried turning it on, then plug the power cord back in, then turn it on again.

 

sounds stupid but sometimes they just need to be discharged all the way.

 

also does it have a master power switch on the power supply? you might have bumped it on accident.

I have no idea if this is a new computer maybe you just built it but you need to make sure that the PSU has the correct wattage. 500w should do. Hope I don't seem like I'm insulting your intelligence

If your computer won’t power on at all, ensure it’s plugged into a power outlet and that the power connector isn’t loose. If it’s a desktop PC, ensure the power switch on the back of its case—on the power supply—is set to the On position. If it still won’t power on at all, it’s possible you disconnected a power cable inside its case. If you haven’t been messing around inside the case, it’s possible the power supply is dead. In this case, you’ll have to get your computer’s hardware fixed
