Any Ideas?

[DukeD]

Hey all. Built a system with Athlon64 3500+, gigabyte sli board 2 gigs ocz ram, PC3200, Raptor 74gig HD,1 BFG pci 6800GT (hopin to get another one day)
One day it wouldn't post. Had been having troubles with this since the build, so I bought a Gigabyte GA-K8N pro board, even swaped out the ram for some corsair (i'll keep the ocz for my media machine), just in case. Assembled it all and..... will not post! No beeps... no nothing. PS is fine, everything lights up, fans run... etc.... but it will not post. Now since all that's really left is the cpu.... do you think that's what has failed? As I said.... new mobo, RAM.... no post. I'm lost... any ideas on how to diagnose this? Is this what it's like when a cpu fails, it's never happened to me before.....

Thanks

Yes....and its often the PSU....the case fans can come on and its still th PSU

Do you have a spare one to slap in real quick?

Even with the Cpu is dead (I THINK) the machine will still post and show the bios but im not completly sure so someone correct me if im rong.

Do you have the 24 pin powr connection and the extra 4 pin connection plugged into the mobo? Read thru the mobo FAQ - it has some great T/S tips for this type of problem.
