Broken motherboard or CPU?

[Noozer]

I took of the heatsink and fan from the CPU and turned the machine on
for 30 seconds and switched it off, the CPU was _hot_, however no
signal to monitor or beep.

CPU is dead now for sure.

OK, I got the new motherboard delivered (same model/manufacturer) and
nothing works

Shall I order the a new CPU next?

Would a machine boot up without or faulty memory and notify me in BOIS?

No, if the memory is barely instable it might make it to the
bios but in general if the memory is bad, or missing, it
won't POST at all or lock up far sooner rather than later.

It would be handy to have known good parts to swap around
the CPUs and motherboards but if you can't do that, yes it
seems a replacement CPU should be tried.

Wrong, as always.

Isn't there a pin-less processor in development too? Maybe by Intel? I
remember hearing or reading something about this. Where the pins are on the
MoBo. Only the pins are not really pins but just little metal dots that
match up to similar dots on the CPU. I think the author called them
connection plates or something similar. Don't ask me how it gets locked into
place. But the CPU and the Socket are shaped in such a way or 'keyed' so
they can only go in one way. (or two if you put the CPU in the socket upside
down.)

Correct me if I am wrong and have stumbled upon a false rumor. I don't have
time to look it up. I should have been asleep hours ago. Insomnia takes
it's toll again.

Yes, if the cpu is working you should get a beep code at least.

Unfortunately, Rod, Award's more recent BIOSes seem to NEED valid
RAM at page 0 to even run the beeper ... I've seen several motherboards that
with no RAM or bad RAM won't even beep, and act like a stone cold dead
MB/CPU.

AMIs might be the same way - it's just that the boards I've run
into this have all been Award/Phoenix BIOSes.

Err - Socket 775. Been out for over a year now.

Err- yeah. I was just too sleepy this morning to remember that. Another
Homer Simpson impersonation is coming I can feel it. [slaps forehead]
"Doh!"

This body is getting too old. I need to find a new host with a smarter
brain. LOL

The AMI's in the P4P800SE's I just put together were silent with good
CPU installed, but no memory. And I've had little success in finding
BIO's POST command sequence documentation, though I haven't
put too much time into it.

I had to remove the water cooling kit from a Socket939 machine but the
CPU came off with the water cooling CPU block because of the sticky
paste while the lever was still down,

You have damaged the socket.......possibly the CPU, and you tried
twice(heat/mangling) to do that, so the odds are greater you did it in.




it looks like the pins are not

 

[kony]

Yes, if the cpu is working you should get a beep code at least.


Wrong, as always.

You might get a beep code for no memory, but neither it, or
others are guaranteed in general. SO the beep can point to
a problem, but lack of beep...

You should still get some form of beep, even if its
only the single no errors beep, if the cpu is fine.

 

[sloblocks]

Rod Speed presented the following explanation :

Only if you have working memory. Motherboards used to Beep if you had
no memory - but these days its very much luck of the draw if they do or
don't. All the boards I've tried in recent years were completetly
silent without RAM.

[which I'll grant you is only about half a dozen or so, I'm not in the
habit of testing things to see if they /don't/ work]

YMMV

Sure, but like I said, if the cpu is good and there is ram,
you should get a no errors beep when the POST completes.

[Logan]

I can't believe you just did that.

Do not ever turn on a system without the heatsink on it.
You may have NOW damaged the CPU, might now have two dead
pieces of gear instead of one.

Those warning and cautions are for everybody else NOT ME, can not happen
here, I never had an accident before, but it was just too hard to do it
the right way. IF IT WASN'T SMOKED BEFORE BET IT IS NOW.
