Hi,
I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
- There's no sign of any attempt to power on when pushing the power button.
- No PSON signal is reaching the 24-pin ATX connector.
- The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
- The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
- If I pull the Super IO S_SLPS#_R pin... -

The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
I have a Gainward GTX 295 with two PCB's which has a broken SLI bridge ribbon cable. As a result, the card is entirely useless and I'd really like to fix it if possible.
I've searched eBay and AlieExpress but haven't been able to find the part.
I believe this same SLI bridge cable is used on the Nvidia 9800 GX2 and the GTX 295 which both have two PCB's.
Can anyone help me on where to get a replacement SLI bridge cable please?
