System will not boot/power up

[ranalli]

I'm sure you guys have read a million of these by now and I did a search on all of them but none of them seem to fit my scenario.

I had a perfectly working computer until my CPU fan crapped out a week ago and then the system would just get too hot then shut down after a few minutes.


I got a new fan, hooked it up, and now the system will not boot.

I turn the power on, the fans go for like a second or two then it just stops....no beeps or anything...


I have an AMD XP2000 with an Abit KD7 Mobo.

I tried clearing the CMOS, reseating the memory, the video card, the CPU, switching CPU fans back to the old one that would at least boot, and disconnecting all non-essential components.

Any clue??


Could the CPU be fried?? Wouldn't the system at least get into the bios though even if it was???


Thanks in advance.

Remove the memory and turn it on. If you don't get any beeps the cpu is most likely fried.

The system would not go into the bios if it was fried in most cases. Does the chip look burned up? How long did it actually run without a fan running? Does the new fan have an RPM wire (yellow in color). Some motherboards will refuse to boot without an override if they can not detect a processor fan running. To get around this, you have to disable it in the bios and while booting the first time you have to push the insert key.

I removed the memory and I didn't get any beeps....same thing happens.

The fan does have a yellow RPM wire too.

I'm not sure how long the CPU ran without the fan but the mobo does have shutdown protection if the temp reached a certain point which it did in fact do since it was shutting down left and right before I figured out the fan crapped out.

So I guess it's the CPU

You don't have a spare CPU to test with?

Even with a dead fan, the heatsink should have been enough to keep the core from heating to the point of damage, when combined with thermal protection on the mainboard.

It does sound like a dead processor though.
