Computer wont POST

[dustin_ds3000]

today my new motherboard can in the mail so i switch them out and i was going to use the old motherboard for the family computer. now the problem isn't with the new motherboard its with the old one. i bought new ram to match the ram i had already amd i changed the cpus heatsink and fan to at stock 462 cooling unit on the old motherboard i put the motherboard in an old case that already had an psu, hdd, and a dvd drive. now when i turn it on all i get is a black screen and the led on the monitor stays yellow. all the fans are running and i can hear the hdd.

things i have tried
removing new ram, removing old ram
new psu
fx5200, and onboard video
clearing CMOS
i made sure nothing was grounded out

im stuck and my family needs this computer so they can stop getting on mine

Just in case

Can you unplug the CPU fan (for 5 secs)
Then turn on

Just be ready to pull the power out if it starts (or either way, after 5 secs)

I have seen issues with the cpu polarities errors causing this, that's all

Let us know if it posts

this seams unsafe but at this moment i have nothing to lose, will try now
ok i tried and i even waited 10 seconds. it did not work

 

[kimsland]

OK, case fan? (should have mentioned that too (also just 5 secs)

 

[dustin_ds3000]

i looked at the cpu again and it looks like some of the edge of the core it broke, i hate when that happens. the amd's xp+ with its unprotected cores. i will confirm this tomorrow with my other amd xp+

I want you to cite ONE reference of CPU "polarities" causing this issue.

You won't. Because what you said is completely nonsense.

I've experienced it myself twice

And I've repaired a stranger (ie a member) here at this board, by quoting the above!
And he replied Thank-you to me. So it does exist!

I don't know all the data/ or power issue that causes it (probably I could find it I'm sure)
But it is TRUE (on minimal cases)
Seeming many try so many options first, I now (through experience) state this.

Citing one thread I'd have to look it up here (definately here)
But why? I already know it can happen!

Processors do not have "polarities".

 

[kimsland]

I'm talking FAN here, by the way !

And as a tech person (possibly like you) I don't like explaining why I Know things (ie you got a few years, for me to explain?)

 

[Justin]

You said, yourself, "CPU Polarities". Read it again.

 

[kimsland]

Typo!

.....Fan
cpu ... polarities
.......^

Thanks for picking that up, for me.
