What is dead/fried? CPU or mobo

post #1 of 16
Thread Starter 
Ok, so I got a computer a few days ago... results that it won't boot, and I'm not sure whats dead/damaged/fried; this is what I know:

-It's a P3 Katmai, 450Mhz Slot 1; Soyo SY-6BB v1.0 Mobo; 2x16Mb Dimm; Cirrus Logic PCI 1Mb video card.
-It won't boot going to the basics: cpu, 1 stick of ram, video card.
-Mobo will do a repeating high-low beeps, apparently award cpu code error.
-CPU... It boots on another mobo(OLD HP), but it identifies cpu as: i(Unknown) - 450Mhz
-Ram is ok, tested with other 2 mobo's
-Video card is ok, tested with another mobo.
-A capacitor next to cpu socket has some orange-brown stuff on top, looks like rust; moves around a bit compared to other capacitors. A few of them look kinda different.

Now, I thought it was the mobo, but if it's fried/damaged, then why does it give a error code? The cpu booted on another mobo, it wasn't identified as a Pentium 3, but speed came up correctly; could the CPU be somehow damaged?
Everything else works fine, so it has to be mobo/cpu problem. Any ideas?

I think the mobo is a dud. It would give error message because some parts of it are still running. The voltage goes through, but the mobo can't get to work. Just my speculation.

Where'd you get the PC anyways?

Yea, might be that; I'm gonna try to get another cpu, see if it works.

LOL... in the trash; saw it and thought it could still work.

mmm try turning the mobo on with nothing... see if it beeps or anything if it gives you the same error.. then its your mobo.. of it gives you adiffferent error..then two things it is your mobo, or its oyur mobo =] . if oyur cpu comes up and stuff on other computers , theres no way its the cpu. as you said everything else works so its not that. your best bet would be to find another cpu that fits the socket and try it in the mobo. if it works then... thats wierd. =] -trey

HAHAHA...n1....i agree...oh, and i'm so flattered i made it into your sig.....did i make that comment to you, but i remember when i did it, just cant remember who to....anyway..back to the task at hand...

Judging by that cap, your mobo is most likely fried....i hate post beeps....i love my asus cause it gives me audible messages...IE it tells me when i f*cked something up...and it does it politely

But anywho, i would try to pop in another cpu and see, but i beleive that is a mobo problem...where exactly is the cap located, because if it is on a specific trace that runs the FSB, it can translate itself as a CPU error.

Well... I didn't mention that cause I thought it didn't have any importance; as far as I know the bios needs the cpu to work, so if there's no cpu, there's no error... meaning that the mobo/bios "works"? Wierd.. I guess the best I can do is try out both on entirely different systems see what happens.

lol @ your mobo.
The capacitor is right next to the socket, and those funny looking ones too. *sigh*

no, bios doesn;t necissarilly need CPU to actually work. Sometimes, esp on older computers, the BIOS chip can run primary functions for bios, but it won't go past post, but it will run the system config, but just not show any CPU

Now that you say that.. I remember a friend that had a computer running without a cpu installed. Although he was running win 3.1; maybe a integrated cpu, or a 486 he had laying around.

Yeah, that's what I assumed. That explains the rust. sknahT for the peR.
