Asus A7V133-One long beep and then shuts off

[typer]

Anyone know what this means....whenever I start my computer I get one long beep and then the whole thing shuts off. Tried 2 different cpu's, my 750Mhz duron, and my Athlon xp 1700+, and same problem. Do I have 2 fried cpu's? Would it even make a beep if the cpu's were fried? As for the motherboard, the fans and everything power up and the green led light goes on. Hope it's not that?? Tried swithching out the RAM for another stick that I know works....same problem. Could it be that my harddrive died out on me?? Woud it even spin up if it was dead? I even disconnected everything except the harddrive, my all in wonder radeon, and the memory, but same one long beep and then the whole thing shuts down. Thinking about bringing it into the computer shop cause I can't figure it out. Thought I'd drop by here first and see what you guys had to say before spending my money on something I could have easily done myself. Thanks in advance. Any suggestions or comments would be greatly appreciated.

Did you change anything before this started happening? A continous tone like that usually means it is something power related. Did you try resetting the CMOS? Do you have another power supply that you can try? Some BIOS have a no fan protection mode that will immediately shut down if no fan is detected. I had a Soyo board that had this, and the fan didn't spin at a high enough RPM for the system to be happy. So I had to disable it, but once when I reset CMOS, it came back on (it was on by default), and I couldn't figure out why my 'puter kept shutting down. Then I remembered it, disabled it in the BIOS again, and was fine.

It's pro'lly the Fan Check Beeping. It's a safety precaution on that motherboard. If you don't have a fan plugged into the CPU_FAN motherboard fan header, the board won't boot. Just plug a fan into that header, slip into the BIOS and turn that option off.

typer, have you solved the problem?? (what was it?) I seem to be having the same problem as you have, one long beep and then it shuts down...
It can't be the cpu fan thingy cause I have it plugged in on the motherboard... =(

I just checked my Asus book and it says "Long beep endless loop=No Dram installed ", so check your memory move it to a different slot ,or get some air and blow out your mem slots
