with no overclock, how long would it take to fry an AMD 3000+ cpu? say the motherboard has anti-heat protection that shuts it down automatically, is it possible?
how long does it take to fry a cpu?

You could jack up the voltage without overclocking it at all and fry it on startup.
If you kick too much voltage through it right off the bat, you could easily fry it before the mobo has a chance to respond.
The CPU thermal protection might shut it down, but even that may not have time to respond if you're pushing too many volts. It really depends on how you go about it. If you've got poor performing cooling that keeps slowly failing and causing the mobo or CPU thermal protection to kick in and shut down the rig, it may never fry because it happens slowly. If you just bump your mobo up to 1.8v and boot up - you may have yourself a new keychain in less than 2 seconds.

what about with no voltage boost at all?
i'm asking because my fan might have some problems and i wonder if it could have made my cpu fry. then fan is very noisy all of a sudden and i am not sure it's running at full speed. i can't boot in anymore.

Well it COULD have, but with thermal protection enabled on the mobo and on your CPU, it's unlikely. That's assuming your mobo thermal protection was enabled. Some people turn it off to test overclocks, and then forget to turn it back on. Not that I have ever done that... ahem.
Anyway, it should be pretty hard to burn up an Athlon 64 just by turning off the fan; they have their own circuit that should shut them down. That doesn't mean you CAN'T burn one up, just that through normal fan failure, it should be pretty hard.
Now, if the fan blew up somehow and your motherboard detects that the fan is not working or doesn't detect it properly; THAT could prevent you from booting up. Some mobos will require CPU fan detection before they will boot. I believe my DFI acts the same way if I forget to plug in the CPU fan, but I'm not 100% positive on that; it's been a long time since I mucked about with that.
Try slapping a new fan on there (and by that I mean plug a working fan into your CPU Fan header on the motherboard) pointing at your CPU and see if it will boot. If it does hit the BIOS and check your temps.

thanks for that. I am hoping the CPU is fine. I think more likely it's my motherboard that got shorted out, cuz the only change since now and before it worked is that i moved it to a new location.
Well that would suck cuz that's a nice Mobo, but when I bought mine it was $160 and now they're closer to $100, so at least you've got that going for you.
I'd try the fan first though. If it's making weird noises, I wouldn't use it anway.

any fail-safe way to detect a shorted out mobo? I mean it does work cuz the computer turns on and the lights on the motherboard work fine.
I'm banking on the fan too, I think the computer is turning itself off because the fan isn't going fast enuf.

Lights on the motherboard meaning the four diagnostic LEDs on the bottom by the last PCI slot? Those will tell you right away if there's a hardware failure.
They count down from all four on to none on, checking your main devices. From DFI-Street forums:
4 LEDs on = Power applied
3 LEDs on = CPU has been detected OK
2 LEDs on = RAM has been detected OK
1 LED on = VGA has been detected OK
0 LEDs on = System has booted to the Operating System.
I'd replace the CPU fan and then try to boot and see where it sticks. If it still sticks.

A64 dont fry like the old athlon xp do, so even if there is no contact with the HSF, the 3000+ should not fry. The 3000+ can run fan less with the stock heatsink, gets hot but does work. So i doubt its the cpu, check thats everything makes contact also see if u can test the cpu in another comp.
I had a similar issue before, my sempron 2800+ system, it would not boot, i removed all components not needed and it booted fine, put all of em back and it still worked, i still dont know what happened to it
