Have one of these boards with some missing components, looking to work out what they are and replace them. Thank you.

The fact that the Super IO has 3.3V (High Signal) on that RSMRST# generally means that this IC is ok. This is present before the power button is pressed, and after. It is the power good signal for +3VSB

Sorry the PS_OUT signal is sending from the PWRON pin from the Super IO. This is triggered after the power button has been pressed, and it is sent to the South Bridge/PCH. In response to this, the PCH/South Bridge sends the SLP_S5 and SLP_S3 signals back to the Super IO. Missing these signal indicates a faulty South Bridge/PCH. So check these next

But it seems like all...

Hi, I have a few similar AM3+ boards with 0000 that i am trying to diagnose. I have been unsuccessful so far but i can tell you a few things to check.

But first i must say, the motherboard will not read the Bios chip until the first cycle of the CPU is activated. Basically there is alot of power checks and signals that are passed around the motherboard before the bios can be read. If these checks fail, the CPU cannot read the bios and the board will not post.

I'm happy that Anikin73 has posted about checking all the main power supplies, I think you can also check DDR15V...

Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

Hi wonderful people. I have a MS-6315 P3 motherboard with very tiny Aluminium electrolytic capacitors. I've made an attempt to identify them from what ive learned so far they might be

Aluminium Electrolytic
G = Series
10 uF
16 = Volt
104 Date code 2001 April? (not really important, but interesting)

Please help to confirm or correct if i am wrong. Thank you

Hi, I'm working on this GA-970A-DS3 REV1.0 as a hobby to learn motherboard diagnostics. Today I found 2 inductors that are shorted to ground. So i am requesting your help to locate the GA-970A-DS3 Schematic and Boardview, to help further locate the shorted component.

Thanks for your time.

Re: Seeking GA-M57SLI-S4 Schematic And Boardview

Thank you

Hi everyone, can anyone help me to find the Gigabye GA-M57SLI-S4 motherboard Schematic And Boardview. I am attempting to diagnose an ALC883 Audio codec, I have replaced the Audio IC with a new one, however the problem was not solved. I believe that if i am able to get hold of the Schematic And Boardview it will shed some light on BITCLK 24Mhz, and SYNC 48kHz clock that are both missing from the Audio IC, after powering on. I think it might have something to do with the clock IC.

Thank you in advance for your help.

Hi everyone I am Sam from New Zealand; I recently started learning some basic motherboard diagnostics and Ive heard about this forum more than a few times during online conversations so I though I would sign up today.

I own computers going back to windows95 Pentium 200MMX, right up to modern hardware. I have a huge passion for all types of computers, operating systems and computer programming.

I love building and restoring vintage computers; there is something about the smell and sound of hardware...
