Question about bad? cpu

[T Ray]

Hello,

I am in the middle of building a new system for myself and have came upon something I have never run into before. First here are the system specs and what i have done to try and troubleshoot the system: Athlon 64 4000+ msi K8N Neo 4 Ultra platinum mobo, 2 gigs of value ram, NEC DVDRW, WD 500 gig sata drive, MSI 7900 GT video, an ultra 500 watt PSU. After putting it all together in the case it would not power up at all no psu fan no cpu fan nothing. I jumped the psu and it came on? I tried a known PSU from my linux box still no power on, I then tried working ram from my linux box no power still, I tried a known to work ecs extreme kn! mobo a friend had still nothing?

I then placed everthing bac on the MSI board except the video card I dug out an old matrox pci card still no power? I am sorry to say I am at a loss I don't have another CPU to try. So my question is can a bad CPU make the motherboard not power up? I always thought the fans would at least spin up and you would get bios beeps? Does anyone have any suggestions that I might try?

Also I tird the stock cpu fan but I also tried another new cpu fan neither came on. I used artic silver 5 on the cpu only 2 rice grains like the directions say.

Thanks in advance

Sorry I should have mentioned that yes it,s plugged in. I
also tried using the reset switch for the power switch just in case the power switch is bad none of it helped. Thanks though

Have you tried building everything outside of the case?

It could be there is a short between the motherboard and the case, causing it not to start.

No I have not tried build it outside of the case, but the backplate lines up perfectly and the second motherboard did the same? I have tried different stands, most everything but the cpu.

It may line up correctly, but if it is making contact inside the case (trust me, I've done the self same thing before) it won't start.

If it boots outside of the case you know that it was something was touching, if it doesn't, then it is a faulty board or CPU.
