Power surge and ASROCK motherboard no longer works..

[Sublux]

I'm so confused as to HOW in the world this could happen...but i built a computer myself abot 5months ago, with an ASROCK extreme3 motherboard, and it was on and working, and then my neighborhood had a power outage for like 5seconds...computer shut off, and wouldn't power back on...my first assumption is the surge killed my Power supply...then i take my power supply and try powering my brothers computer with it...works fine, but my computer no longer powers up...is there anything else that could of happened aside from the motherboard being fried? or is there anything i can do to Check the motherboard is broken before i buy a new one? or that buying a new one will even help...really need help ><

Use a Surge Protector. This one doesn't cost too much. Sometimes they are on sale for a lower price.

Open up the case and double check the wire between the power button and the motherboard. Try unhooking and rehooking it and see if it makes any difference. If not then do a reset on the motherboard using the clear CMOS jumper. Make sure if it does fix it then go into the bios and set everything up once your computer turns on.

Do you get any lights on your mobo or any noises/activity when you hit the power button on the case?

What are your specs, BTW, so we can possibly help you a bit more?

i also tried changing the plug for the power button and resetting the CMOS..neither did anything ><

I think you can jumper the "PWR" switch on the mobo, so you can bypass the switch (take it out of the loop). This will ensure that the power button isn't the problem (not likely though). And since you used the PSU on another build, with no issues, I'd say that the PSU isn't the problem. I would have to say, if the jumpering the power switch on the mobo doesn't do anything, that the Mobo is dead. I then would RMA the mobo and get it fixed.

what do you mean by jumpering the power switch? how do i do that so i can try that first. and damn..yeah i assumed at this point that the mobo had to be dead but wanted to try everything i could in the hope it isn't and i need to get a new one haha

Jumpering the "Power" switch is by shorting the 2 leads (posts) that are in the mobo (where you plug in your PWR connection from the case front panel connections). Most people use a small screwdriver to accomplish this task. All that the mobo is looking for a is a closed (shorted) circuit from the power button on your case. It is only needed momentarily to start the boot up/power up process.

Like shorting the 2 posts (yellow in color) for the PWR BTN in the picture above.

So i know it isn't the power button and i'm now not convinced that the motherboard is dead...i took my brothers power supply out of his computer thats older, and just put the main power cord into my mobo and powered it on, and the CPU fan started up...but i can't tell if it's working past that, if the motherboard was "Dead" would the cpu be able to power on still? is it possible that theres some kind of problem specifically with my old power supply and motherboard not working together anymore? some kind of like connection problem or something that simply doesnt let them specifically work togethor, but both still actually Work? or is it just possible for the cpu fan to power on without the rest of the mobo working?

----edit
I just tried with a normal brand new power supply to power up my computer, from what i could see, Everything powered on fine, the gpu fun and CPU fun's kicked on (which they didn't with the power supply ive been using for this pc) but the front LED panel on the case didn't come on, and the monitor wouldn't respond so it seems like it's not working still...but thats alot more then i could get out of it before...so idk what to do, is there anything that could cause a power supply to stop working specifically with a motherboard while the mobo and PSU still can work apart from eachother..? or is there anything i can try to see if its just something silly not letting the monitor turn on that i could try before i scrap the mobo?

So with a newer PSU you can get everything to power up, but the video output isn't working?
If your using just the onboard graphics (iGPU), that is supplied by the CPU, since you have the CPU/GPU in one package.
If you have the right cables, you could try the HDMI, DVI, or VGA ports to see if you have any output signal. You could even output the signal to a newer LCD TV with the right ports, if you had that option.

That's exactly what happens, i went and bought a new PSU yesterday and tried it in the computer, it booted up and i tried everything i could it just wouldn't display video, and the LED on the front of the computer didn't work.

i couldn't think of anything else so i went and returned the PSU and bought a new motherboard, replaced it with a nearly similar but different chipset Gygabite mobo, and i just finished putting the rig together with the new mobo, and my old PSU, and it turns on, gives video and appears to be working. gave me a bluescreen at first so i've got it reformatting currently, but hey, a bluescreen is better then no screen sadly...haha but yeah anyway it appears to be fixed!

Tl;Dr - My problem came down to the motherboard being fried, i bought a new one and it seems to be working again, doesn't seem like anything else was damaged so far. 🙂

Moral of the story; an actual surge protector would of been great to of had beforehand...definately buying one now to prevent this in the future. lol, thank you for your replies!

Glad I could help you out and that you didn't have to buy too much to recover
