motherboard speaker not working

[Tomas_269]

Hello, i have a m5a97 pro motherboard, and need to troubleshoot it since it doesn't POST. But when i try to connect an "aftermarket" motherboard speaker to the specific pins, nothing. I tried reversing it, nothing. It was that 4-pin with wires on both ends. Separated it, and then connected the red wire to +5V and the black wire to GND (closer to the +5V, was not working on the other GND). It produced a mettalic clickity sound, and started to heat up. What should i do?

Well, have you considered the possibility that speaker was perfectly ok, it was just that your motherboard was not beeping at all? Which happens a lot when motherboard is faulty ...

The 4-pin case speaker or piezo has to be connected as is; you don't need to split the connector http://www.tomshardware.com/answers/id-2596917/connect-front-panel-connectors-thermaltake-core-v71-asus-m5a9-pro-motherboard.html You may have a custom speaker specific to the old motherboard it came from. What speaker are you using? If it doesn't work, then simply buy a piezo like https://www.newegg.com/Product/Product.aspx?Item=N82E16812201032&cm_re=speaker_case-_-12-201-032-_-Product

I have both 1,5V and 5V of those speakers, but none of them seems to work 🙁

I've never seen a case speaker that supports 1.5V and 5V; they all are 5V. You seem to have a non-standard case speaker.

Well, i bought them "aftermarket". One was something that you can order on ebay, simply 4pin connector with two cables and the speaker itself. This didnt work, so i went to a store and bought a 5V and 1.5V one, since i had not much time to google which one i needed. Thought, i found it fast enough to not use the 1.5V, but the 5V is not working either 🙁

At this point I have to agree with DRagor; your motherboard seems to be defective. You already tested with a known good PSU, a different GPU, etc.?
