I recently built my first rig a few months back and everything was working fine except my graphics card..and, well thats a different story.

Earlier today I was putting my graphics card into another PCI slot to see if it would fix the problem; to no avail. I was told to remove the battery from my mother board to reset the CMOS, but when the battery came out, it flew onto my mother board. I had a gut feeling that I just messed up the motherboard then. So I finish putting all the components back together and close my case. I plug the PSU cable into the PSU and switch the power on it and the computer acts like its turning on and off without me touching the power button my case. Now I am thinking "f***". I have no clue what could be wrong, other then my MB being done for.

I linked a video of what is going on. It shows the blinking indicator light on the front, with the faint sound of the fans turning on and off.

As for the model MD: GIGABYTE GA-MA790GPT-UD3H

Thank you in advanced :)
 
Hey, cool. Same case.

Gigabytes tend to have issues from what I've read. If you have another mobo to test it out on then that's what I'd do. Or RMA if you still can.
 
Gigabytes go into a reboot cycle when attempting to automatically set the bios. You either put in some bios setting that is wrong or too agressive or did not properly clear the bios and the machine is confused.

pull the plug from the wall.
remove the battery
put the cmos reset jumper on
let it sit for at least an hour.
remove jumper
replace battery
plug in
boot and go directly into the bios.
Choose "set to optimized defaults"
save and exit
reboot and do what you need to do.
 
I will have to try this out later tonight, thanks for the info.

Hopefully it works, if not then I will let you know

Interesting... I've used gigabyte exclusively for literally all desktop builds for the last 3 years and no problems with any of them. I take that back, I did RMA one due to a botched bios flash. They are in fact, very solid boards.

As to the issue at hand, it's an interesting one. I would start by removing ALL non-essential components. ALL SATA and IDE devices, ALL USB devices and just keep a single stick of ram. I would even disconnect all the case LEDs as well as the power/reset buttons and simply use a conductive object to power the system on. If it powers on when doing this, then start adding one component at a time and see when the problem comes back.

I tried just leaving the battery out for an hour and making sure all PSU plugs were properly placed, unfortunately the computer didnt start but the Case, Heatsink and GPU fans all ran without the computer turning on.

I plan on doing tomorrow after I get out of class. So I should unplug my hardrive, GPU, system fans and dvd drive? That is basically all I have plugged in, along with the PSU and heatsink and cpu.
 
bascially all you need plugged in is the CPU, a video card and a single stick of ram. keep the heatsink fan plugged in becuase a lot of boards will shut down right away if they don't detect a fan. You don't even need a keyboard or mouse for the PC to POST.

My mobo won't post without at least one of the four pin 12V connectors connected.
 
Well yes. But you still said only those three. You do need one 12V as well. ;) in addition to the 20/24 pin power supply.
 
Most people don't need clarification that you need power to the board for it to power on. Is there a reason you're continuing to spam this thread?
 
Just trying to help him bro. You'd be surprised how many people forget the little things.
 
Fair enough... Yes, you'll need to plug in the ATX and the 4 pin (or 8 depending on the board/psu) 12v connector.

Sigh. So I did what you said and tried to power on, to no avail. :(

I put everything back in the way it was before and I got nothing again! I could wait until friday to have my girlfriends parents look at it (both computer engineers), or pay $80+ to have it repaired. I have my resumes on my computer, which I need in order to apply for a job. :mad:

I will keep trying to figure it out though. Any other suggestions?
 
How many ram sticks do you have? If you have more then one, try swapping. You can also try resetting the bios. Don't remove the battery, just use the jumper which should be near the battery. If you have another powersupply you can try swapping that temporarily. Ultimatly it does look like it might be a board problem unfortunatly.
