Power Switch

Aeil · 06-13-2009, 05:19 AM

Okay, here's my problem: The button that turns on the computer doesn't work anymore. I was wondering what would be some reasons for this and how to fix it. I saw the "how to bench test your computer" thread and it said to touch two of the pins with a screwdriver; well I tried that and it didn't work.

I have a Sigma Unicorn case: http://www.newegg.com/Product/Produc...82E16811226031

an ASUS Striker II Mobo: http://www.newegg.com/Product/Produc...82E16813131293

And this PSU: http://www.newegg.com/Product/Produc...82E16817379009

Thank you for helping!

Can you borrow another power supply to try in there? Sometimes, even a new one can tank, so you have to RMA it for a replacement. If you touched the two pins like described in that sticky and it didn't come on, it is likely NOT your switch that is bad.

Well there are lights on the mobo that turn on when I plug in the computer. Should I still try a different power supply? Also I don't have a spare PSU that I can use; I'll have to go and buy a new one.

Also, I'm looking for some things that I could do to easily fix it. If none work then I'm planning on handing it over to a computer repair shop. But I want to try to do it by my self first.

Did you try all the things in the Bench Build Sticky? I would go that route if it were mine to see what interventions might do for you.

Is this a new build or has it worked before?

Have You:

reseated the 24 pin ATX connector?

Connected the motherboard molex from the power supply?

Connected the CPU/Heatsink fan?

Does it do anything and if so, what does it do? (like does it start for an instant and then nothing????)

Well, I hadn't tried everything in the bench build guide. But, it was working before. When it stopped working I had found the computer on (when it was supposed to be off) and the fan was continuously running. The power and reset buttons were unresponsive so I unplugged the power cable and the buttons have been unresponsive since.

edit: also there was nothing on the monitor when I found it on.

I'll do the whole bench build thing, but it'll take me while to get around to it. I'll post a reply when I've finished.
