Old pc need repair

[lior1111]

Hello, 

I need your help, 

Im trying to fix an old pc for a teacher that has 0 idea about computers. 

The pc wont turn on, its probably a psu issue. I want to replace the psu but the thing is that she has no clue about the model of the pc / motherboard and neither do i. And it looks like a prebuilt.

It doesn't even say anywhere on the case whether its a dell or an hp pc.. No clue. 

Anyway, so if i want to replace the psu, how am i gonna do the wiring? Front panel wiring is gonna be like a guessing game right? Any ideas? 

Thank you.

If it's a PSU problem, just buy another PSU provided the case doesn't need some wonky proprietary design.

 

What happens when you try to power on?

Take the side panel off the system, post a full, clear, pic of the motherboard here, and we can help.

Don't touch front panel. Those are connected to the motherboard and not the PSU. Also, are you certain the problem is the power supply? There could be any number of issues.

Pretty sure man, the pc just doesnt show any signs of life and electricity.

Could still be the motherboard. If front panel power button doesn't do anything, the system won't try to power on.

That's a blurry shot, but as near as I can tell, it's a standard micro-ATX board with a 4pin CPU power plug and a standard 24pin for main power. Any modern power supply will have those connectors. Don't touch anything else but the power plugs going into the board, and you'll find out quickly if it's the PS or something else.

The motherboard may still be to blame, so if you have a loaner power supply, I'd recommend testing that. You can also just check the connections to the components from the PSU.
