Hey,

I built a testing setup to check some old SD-RAM bars:

- mobo ECS K7S5A
- CPU XP 1800+
- VGA Nvidia TNT2
- PSU: some OEM
- loose PC speaker connected to mobo to evtl. getting any error beeps

Worked fine so far for several RAM tests.


But today it didn´t boot nor show any screen, no error beeps.
So I figured out that the small PC speaker had a short-circuit
("+" had contact to the speaker body due to a tiny isolation damage of the wire).

I disconnected from PSU, cleared the BIOS, took off the battery - didn´t work.
Plus took off VGA, then plus RAM, then plus CPU - didn´t work.

It´s dead, isn´t it? :ohwell:
Btw: Should error beeps (fixed the PC speaker) even appear when ALL components are taken off their place?

Given the poor build quality of ECS boards, it wouldn't surprise me that something as trivial as a shorted speaker would render the entire board unfit.
