Hi There

I have this mobo and its been great am interested to see any photos you may take. My first thought was the short was caused by the stand offs on the case you swapped it into to.

If it's the PSU that's caused the problem it could have taken anything and everything out.
That is very rare though, and you would usually see scorchmarks on graphics cards etc.

If (as is more likely) it's a defective mobo then I doubt anything else will be awry.

Hi Desktopstu,

Thanks for the reply.

I'm yet to investigate this problem properly as of yet (been working away from home) although I will tonight.

One of the components on the motherboard did glow bright red and let off a rather large amount of smoke; the said component has now turned white - but again, I'll investigate tonight.

What are the odds that a blow out on the motherboard has ruined my other hardware (graphics card, ram). Slightly worried as this system wasn't exactly cheap to make :(

Anzo, theres likely to be two parts of the board thats blown.

circular capacitors (if your not sure what they are, they are little round barrels standing up on the board) one of these may have blown. This can be replaced but to be honest, its both fiddly and fraught with potential problems, the other one could be the cpu power regulator (think thats the right term) it would be a small black block with three pins coming horizontally out of it and going into the board. I have replaced power regs on one of my old boards (involved ripping one off a similar board and actually selotaping it to the board! worked too for a while) either way odds are its a deadun.

Be careful about using the PSU again- try it on a known to be working but cheap and disposable board first as if the PSU is responsible it will become a serial killer. This comes from personal experience of a vindictive serial killer PSU that received the hammer treatment after it blew two board in quick succession. it will claim no more lives now.... vengeance was swift and permanent.

Odds are if you installed the board incorrectly and shorted out on a spacer or on the back plate (as I have done in the past) it just wont boot and (usually) no harm is done.

Sugar...not really what I wanted to hear but thanks for the information.

I'll take a photo of the motherboard tonight and highlight the component which burnt out (its now turned bright white) and contact Gigabyte in the morning.

I'll just hope and pray that its not destroyed my entire PC :|

Thanks for the information though guys!

Hi anzo :)
You might be well advised to deploy your nose and eyeballs first to check that it wasn't a simple error made by you in re-installing your socket 775 board, like a spacer short that would invalidate warranty. If you can remember what glowed red that will help, but once you have removed all power, sniff for weird burnt smells and in good light, look for scorch or burn residue. Whatever you do, don't open up the PSU as its high voltage capacitors can even retain a lethal charge, but you may detect a burnt-out smell from it. ;)
In my experience it's P965North Bridge, ICH8South Bridge, GigabyteSATA2 and IT8718 housekeeping chips that are the most vulnerable, rather than the CPU and other components, but you may end up needing to do a progressive re-build and check to find out what's survived. :hehe:

That boards dates from 2006, what revision is it.
Gigabyte warrenty was 3 years,it's worth contacting Gigabyte as it should be covered.

Morning all,

I recently built my old(er) computer into a new case. All went well until I came to turn it on. A component on the motherboard suddenly glowed red, let of a bit of smoke and it was obviously too late.

Now, I have no idea what caused this to burn out. Now I have to buy a new motherboard but if it a fault with my PSU or any other component, how will I know?

The model is a Gigabyte GA-965P-DS3 - is there any kind of warrenty of manufacture guidence I can use to locate the problem so I don't blow out another motherboard?

Thanks,
Matt
