Boot-up problems

I have a PIII 900 MHz that has worked fine for 6 months. Now when I try to turn it on I hear the fans and lights on the front come on but I get no video output and after 10-15 seconds I get a two tone alarm that sounds like a British siren.
Anybody got any ideas? Thanks

Yes, the alarm could indicate (varies by motherboard) that the CPU fan might have died and the processor is probably overheating. It could indicate a different problem. Larry

I checked the fan and it is running. I dusted the area and checked the RAM chip. Alll appears ok.
Thanks for your interest.

I had a similar problem. It was a fan alarm, it was sluggish during bootup, enough to set off the alarm, but then spun up to full speed. Apparently there is no MB reset, even if the fan is working later.
Hope this helps,
Dave
