Bad CPU??

[jterrell]

I am building out a pc for my nephew.
I have built out probably 200 pc's (granted 199 of those 3 to 8 years ago) and never had anything close to this much trouble.
In fact it's usually something silly I missed.

But this build is driving me nuts.

I had my nephew order a amd 64 3000+ 939
A VNF4 board and 1 gig of mushkin green pc 3200.

pci-express Winfast 6600 GT card.

Basically same system I have.

This system would not do anything on power up tho.
I tested power supply(ocz 450 watt) with a tester and it passes.
If I hook up the tester to the 20 pin, the 4 pin to the mobo and the case fans to the psu I can get it to power on.

I have the mobo just on the box outside the case.
I've tried clearing CMOS.

WTFrick could it be? My guess now is bad cpu. I am dying here as he waits patiently to play WoW and I am noobing him hardcore. Any help would be greatly appreciated.

thanks in advance.
joseph.

Try shorting out the PWR SW (power switch) pins on the motherboard with a spare jumper or something similar to see if it will turn on that way. If it does, the switch in the case is bad.

If that does not work, try your CPU, RAM and PSU in his computer (one at a time), and his in yours. If your system works with his hardware, (particularly if his does not work with your hardware) then the problem is likely with his motherboard and it should be replaced.

Yea, gonna have to break down and get soem more arctic silver 5 and test the cpu in my box. Tried everything else and they all work.

geez, it gets worse instead of better.

i rma'd the mobo and got a replacement.
tried it and same deal, no luck.

figured it had ot be the cpu then since the vid card and memory both proved to work on known good systems and the psu passed a psu test.

soooo took apart my good system and cleaned up the as5 then tried it in another system with more as5 applied. no difference.
booooooooooo!!!!

wasnt sure what else to try but figured hey let me get the main system back up and running.
cleane as5 then reapplied and plopped it back in.
now when i start system it will only spin up for seconds before shutting off.
my guess is a heat issue but man why?

this is seriously driving me nuts.
i must be getting senile because i have simply never encountered this level of probs before.

anything i can try that wont drive me even battier is appreciated.
i am pretty flustered so the less thinkng involved the better, lol.

try the cpu in your system, if it works there then... umm i have no clue, but not, then you know its the cpu.
