762799 2009-04-06 15:26:00 Hi Guys,

Please read this and guide me.

I bought the motherboard 1 year ago, in Feb 2008.

Few months back, I changed the Graphic Cards and Shaved its Audio CD in Port to make room for GTX260x SLi.

Ran fine but after few days it stopped posting, the fans will run and the LEDs will be on BUT there will be no post. I changed the RAM to First (Green ones) and the PC started, So I was running in Single channel.

Later I changed from 650W Antec to Corsair HX1000W. All running well.

I decided to change the processor from E8400 to E8500 E0 (Stupid me) the PC started fine and well, no problem. Ran few tests with the processor all was well.

Then I went into the BIOS to OC it, FSB set to 450, and Volts to max White (not red) for CPU only (dont remmeber exact, but no Red color Volts), rest was left as it is. The PC booted BUT during Vista mid it stopped and shut down. (I use Thermalright Ultra 120)

NOW what happened that I press the Power Button the fans and LEDs of fan will start for a Fraction of a sec and then it will die. The Red LED of the board was On.

I tried again and again but in vain, I changed to old processor, same results.

I changed the Power supply (PC Power and cooling 750W) Same.

Then once I pressed the Power Button, immediately all fans started BUT there was smoke and this part (Pic) burned out and there was Electric Buzz running through the PC giving me tingling sensations.

I removed everything power cords etc etc but there was current STILL. I removed PSU took it out too. After some seconds PC was Quiet. AT that time there was no processor in the Socket as I was testing for Beeps or anything.

Anyways I tested the PSU (Both) with that Shorting Jumper technique and they are powering up fine. I bought a Multimeter and tested volts in various leads and the PSUs are giving 12v,4v and 5 Volts on various Points for Motherboard, CPU Lead is giving 12v at yellow ones, and the PCI-E also 12v on yeallow, Peripheral 12v and 5v. ONE point give -12V at Blue Wire???

PLEASE HELP and guide me as to what happened. I will be getting a core i7 and stuff, and I am afraid to boot it :groan:

762800 2009-04-06 19:48:00 It looks like the mobo has blown as you said, I think you have fried it and it will need replacing, did you have all the leads plugged back in the right way and in the right places? gary67 (56)

You did what?? Shaved?

You've killed the motherboard. 		pctek (84)
762802 2009-04-06 21:20:00 The board's dead. From the looks of things, it could be a voltage regulator as you said.

RIP motherboard. :p 		pcuser42 (130)
762803 2009-04-06 21:35:00 I don't know what you did to remove the CD Audio connector but I doubt that would have caused the problem. Could you please explain what you did, though? Perhaps some metal filings from your 'shaving' worked their way somewhere they shouldn't have.... Agent_24 (57)

Thanks for the replies guys.
No No its a plastic covering the Pins that was shaved off. The GTX260 has a large Plastic protruding at the bottom near the metal.
The MSI board has a Audio port Right ahead of PCI-E Slot, See here;

Anyways the shaving off was necessary to make the Card go in, as it was not. BUT the board worked fine for 2months or so.
The above mentioned problem happened when replacing the Porcessor and overclocking it.
I am not worried about board, but, just want to know what happened?
I am gonna get new corei7 stuff soon, so is it safe for me to fire it up with these PSU?
Thanks 		devilhimselff (14807)
762805 2009-04-07 14:27:00 Perhaps the increased load with the new CPU + overclocking caused too much strain on the VRM and blew that MOSFET? (perhaps that particular one wasn't feeling OK to begin with) Maybe the GTX260 itself was using too much power for that board design?

Your PSUs are probably fine.

The blue wire is meant to supply -12v. White wire supplies -5v but now motherboards do not require it so most PSUs now do not have one.

This is for the standard ATX spec only. (pinouts.ru)

Some PC makers like Dell/HP etc have in the past used the same connector but with different colour coding and electrically different pinouts.

To cause even more confusion, some PSU makers make ATX PSU with the correct electrical pinout but different colours (I have seen this on Aopen PSUs) 		Agent_24 (57)

I seriously doubt that. I've put a few high end large cards in boards with the audio in exactly that spot and never had any problem. You probably didn't have it lined up right. 		pctek (84)
762807 2009-04-08 18:22:00 THANKS GUYS for the replies and Help.
@ Agent 24 thanks for the Help man, I checked my PSU(s) both, and they are working fine.

@pctek, Nope tried everything, if you search google many people are having this trouble :(

I guess it would be safe to put the new Rig on the PSU :waughh:

Any other thoughts are appreciated. 		devilhimselff (14807)
