A7V No boot - Siren sound

[e. r. m.]

I have an A7V that stopped working. When I power up, there's no video
signal, and a get a beeps that sound more like a siren. I've swapped
the agp vid card to a pci vid card that works, but still no go. I've
already removed all cards, ram, drives, but still get the siren. The
only things I can think of to replace would be the power supply, cpu, or
mobo.

Anybody experience this before? If so, what was the offending unit?

I know you've mentioned the removing the hard drive, but is it a Western
Digital model by any chance?

I started getting a two-tone siren on my Asus K7M after 5 months, (all
new parts). I under clocked the CPU from 800 to 500MHz and it ran just
fine, so I replaced the PSU with a better one (250W for a 350W) and it
solved the problem.

That's the only experience I've had with the Asus two-tone siren, AFAIK
it could mean other things as well.

Good luck,
Ed

what about WD harddrive with the A7V?
I have a A7V8X-X and won't see my gforce 4 mx440 video card,so I replaced
for a old vodoo 16mr card and work fine.I don't play pc games it all,so I am
okay.
And I have a WD hard drive and I don't have any drama with it.

Because certain models of WD hard drive have a failure mechanism that
sounds not unlike a siren going off. Could be that OP's hard drive
might be dicky.... Had to RMA 2 WD hard drives about 18 months ago that
had failed inside the warranty period and demonstrated the "siren".

And my board wasn't an A7V so it might not be relevant.

HDs are WD & Maxtor. They're both disconnected and I still get the siren.

Thanks. I'm suspecting the PSU is the likely culprit, as well.

OK. Hope you're able to sort it out.
