Coils in the vicinity are not shorted and are at 1.05-1.06V.

Board now stays on but doesn't get past qcode 00, dram led on as well. I've spent too much time on a board and architecture that is getting old. Time to upgrade

Thanks a lot for the help, it's been informative in many ways!

2.4k...

With the new IC I'm getting 1v on pin 5 when turned on.

For a very brief moment the board tried to boot(QCode stayed at 00, memory led turned on). I put a RAM stick and proc, tried again, got again memory led. Then it went back to the on/off cycle. I don't know what else to check, about to give up....

IC is not heating anymore.

Everything was properly cleaned after removing but I didn't check for shorts...

3 goes to 3.4V when powered on
4 is always at 5.1V
5 is at .615V at all times. Can it be that this IC is fried as well? I have another 2 so I will replace it again and this time will check for shorts....

There is a possibility that the 2 capacitors in the photo need to be replaced, but I have no way of knowing their value(don't have a capacitance meter, Ohm meter shows they are open). If you can get your hands on a schematic(couldn't find anything) and get their values I'd be happy to replace them and see what happens. The rest of the components are so tiny that I'd never be able to replace.

Hi,

I did just yesterday, but unfortunately the problem persists, it seems to be some other part of the motherboard(

If you do find a solution let me know!

Fantastic

May I ask how you figured out the YM bit?

I ordered a few from Aliexpress, in a month I'll know if that was the only issue. Thanks again!

Thanks a lot for your reply, I'm sure this will be useful for many things in the future

I went through all the Richtek PDFs found in that post, but found none with a 29 marking code.

I put 29 in the cross-reference tab at Richtek's site, got nothing, as it needs at least 3 digits. I added a 3(the first digit from the rest of the code on the IC which should be the date and therefore should not be used) and got LM2936 as a result which at least is an 8 pin IC but definitely wrong. I desoldered the IC and it has an exposed...

Hi all,

I have an Asus X99-a II board that has been my main computer for a few years now and I would like to continue using it as I cannot afford to move to a newer platform and it still serves me well.

Here's what happened. I had a leak in my house a few weeks ago, and my guess is that a few drops of water fell on the chassis and found their way to the motherboard, either that, or the board just decided to die on me now but the coinsidence is too high to be ignored. I had used it prior to the leak and it worked just fine, then I turned it on last week and the following...

Hi all,

I've been tinkering all sorts of electronic boards and devices since as far back as I can remember, I'm here to troubleshoot a faulty motherboard
