Help Please

[swd193]

Hello,

I have an Antec 900 case and the power button has been going bad for the last few months. Last night I powered down and it won't restart.

I removed the power switch and swapped it with the resett, and still doesn't work.

I then cut off the power switch and made a direct connection with the two ends, still not working.

I then read an article that you can test it by directly making a connection by using a screw driver to connect the two pins on the motherboard. Still didnt work.

My question: Is there a way to bypass the connection on the mother board?

If these pins are dead does that mean I need a new motherboard?

Does anyone have any idea for a fix for this?

Thanks for any help and happy fathers day.

Oh btw the motherboard is an Nvidia Nforce 680i SLI

Again thanks

Hi, first and foremost, welcome to AnandTech. And also Happy fathers day to you (if you are ) and to all the Fathers out there.

To start off with helping you in this matter, do you have all the connections in place and in securely. Double check. Also, is your power supply on? Double check that too. Try taking a paper clip or find a jumper tab of an IDE HD or something, and use that instead of a screwdriver. Make sure you are crossing the proper power pins on the motherboard. If that doesn't work, look over your board and see if the pins have broken solder joints. hopefully they don't, but just check to make sure. If all is good from what you see than after that point, I would advise someone else with more in-depth exp to comment with your dilemma.

What PSU is this? I've never had any problems using the screwdriver trick to "jumpstart" a motherboard.

The OP is stating the motherboard not the PSU. Even though, it is more accurate to use something else like a jumper tab rather than a screwdriver for someone with little or no exp. I just wouldn't tell anyone to just poke around, so to speak.

Thanks for the responses.

I tried the paperclip and got the fan to jump for a sec then nothing. I had this same thing happen with the screwdriver once.

The power supply is a BFG 1000W.

There is a blue light at the top right of the motherboard that turns off when I power it down from the back of the computer and comes back on when I power it back up from the back. Note the computer still doesn't start.

Thanks

Op, this is sounding more like a hardware problem rather than a switch problem. Do you have other hardware ( parts ) to test with?

@ Drsignguy - I've had a failing PSU cause issues with starting a rig up. Ya never know.

The only thing I can think of at the moment is to make sure there aren't any electrical shorts. I've seen case shorts cause the same type of symptom, where the rig powers up just long enough to cause a fan to move slightly.

Oh, I don't disagree with you ay all AmberClad. Wanted to make sure we are all on the same page.
And Yes, I to have seen and heard that shorting out the mobo does cause symptoms like this. Good call!

Again thanks for the responses.

For several months everytime I would shutdown the system I had a very hard time restarting it. I would have to hit the power switch several times and it would just start then stop. I tried not shutting the system down for fear it wouldnt re start.

Then I had an update and accidently hit the shutdown button and now it won't restart.

It ran fine as long as it was on. But starting it was becoming more and more difficult.

 

[swd193]

I don't have an extra psu or motherboard to test this with.

Is there a way to tell if it is the motherboard or psu?

Thanks

 

[swd193]

I don't know if this helps but when I turn the power on from the back of the computer (psu) I get a big hit of feedback from the speakers and the blue light on the mobo turns on. This happens everytime I flip the switch on the psu.

 

[Drsignguy]

Not to familier with the Nvidia MoBo but I am going to assume that is the LED power to the MoBo. This means you have power to it. Give us ALL your hardware involved here. We need to know what you have on your rig to isolate the problem. Seems to me it's the PSU or the mobo. But we need all your specs to make sure. What is the wattage of your PSU as this would help.

Hello and again thanks for the help.

psu is 1000W. This is a system I had custom made from compusa a week before they closed up there stick and brick locations.

Antec 900 case
nvidia 8800 gtx gpu
sony dvd
cpu is dual core 6800 extreme
running vista ultimate.

Hi, sorry so late but work prevails.

Nice Hardware there swd193! Anyway, I have been thinking about this and the only thing I could come up with to try, is to have some other pieces parts to test with. Some things you could do is to check out your motherboard power connections to see if all are connected properly and if there are no fried plugs. The one I am concernd with is the power to the CPU. If not fried = good. Also check that main harness to the mobo. Make sure that all pins are in and making connection. Double check the mobo itself like "Amberclad" had sudgested earlier. Something may be shorting it out. After all you have done to check and making sure all is up to par, Then you may just need other parts to test with. Call a friend and ask if you can borrow........... and do some testing. Starting with PSU. My gut feeling is going towards Mobo........Hope you can get this resolved.
