Motherboard Problem - Dodgy CPU?

Hi,

Hope someone can help with this question.

Is it possible for a dodgy CPU to fry a motherboard, the reason I ask Is that I swapped a CPU in a test board & it didn?t work, so I put the old one back in, but that didn?t work either & now the board won?t boot at all.

I realise that it might just be coincidental that the board failed at that time & it?s also possible that static caused the fault but it seems like the CPU is most likely responsible.

Any help would be very much appreciated.

Regards

CDH

that it could fry the motherboard especially if it has a short in it.

Thanks for the quick reply cmiller5400

If it is possible it looks like that?s what happened. New lesson learned.

Reset the BIOS/CMOS using the Jumpers? I would try that... might work...

Thanks tkrl26

I checked all the obvious things but still nothing. The machine is one of my test bed PC?s which I use all the time & I?ve replaced the bad MoBo with one exactly the same & it?s fine so I can only assume it was the Duron 700 which caused the problem just didn?t know how or why.

And destroy the M'Board when they do. Funnily enough I haven't had a single case of a Failed Intel CPU yet and I have quite a few old Intel CPU's ranging from the 486 Days that still work perfectly long after the M'Board has died.

I have yet to keep a single AMD CPU though. These just seem to die and take the M'Boards along for the ride.

Really, I?ve never even heard of it before. Oh well I?ll just have to be more careful in future.

Thanks again

Hi,
I've been running AMDs for years now and the only troubles I've experience is when the cpus were mistreated.
AMDs differ from Intels in the way they work when they overheat. Intels have an internal temperature sensor that slows the cpu's clock if it gets too hot to keep it from expiring. AMD's don't, they rely on the mobo to sense the temp and do something about it, usually a loud alarm that scares the sh!t out of the user and if nothing is done to fix the heat problem a total shutdown.
Having said that I have seen AMDs that had misfitted heatsinks or no heatsinks blow in seconds, some of them obsolete units for curiosity, the others from "user" messing around.

The moral of the story - keep your heatsink free of dust, and if you ever remove it make sure that the heatsink paste is fully removed and high quality fresh paste is applied.

'"user" messing around'

Ha ha yep that's me. I've lost a CPU before when I booted without a heatsink or fan. I just wanted to check out something in BIOS & I thought it would be OK for a few seconds. Wrong.

I'l follow your advice in the future ozi Eagle. Thanks for taking the time.
