Computer shuts down itself

[WaterCup]

Hi,

Just a few days ago my computer suddenly turned off on its own. Without thinking much, i turned it back on, and later that night I realized both fans on my PSU have stopped working. So I thought that was the cause. So I replaced the broken PSU with a new one, but to my surprise, the computer shut off itself again after a while. (I turned it back on and have been using it since without problems)

Then I checked the motherboard and found there are some minor leaking on some of the capacitors. Could that be the cause? What should I do to fix it? Thanks very much..

Bad caps for sure, you can either replace them if you are good with a soldering iron, or you can replace the board.

Definitely a bad board like Rad said. I'd look to invest in a new motherboard or mboard/cpu combo if i were you.

Thanks everyone. I am in the process of buying new capacitors and soldering them on the board. Hopefully it will work out.

If you haven't already, you might check out the soldering advice on badcaps.net. There's some detailed info about making sure to get the solder well down into the hole and not just on the outer surface of the board.

FWIW, I just had the same exact problem with a 5-year-old Foxconn mobo. A couple caps are barely leaking, but they are leaking. And the machine kept freezing up and then rebooting itself.

As I understand it, caps don't even have to actually leak to go bad. Apparently over time, the liquid electrolyte solution inside will turn to a gaseous state and expand inside the cap, causing the top to bulge and/or leak. So even if they're bulging and you're having probs, the caps could still be bad even if they're not visibly leaking. That's my understanding, anyway.

Happy soldering.

This is why you should only buy a mobo with all solid caps.

I did spend the night reading from badcaps.net, excellent website.
