Cpu needed to reset motherboard?

[shevanel]

Has anyone ever heard of a cpu needed to reset motherboard to working order?

I have a MSI K8N with 3500+

The 3500+ died in an overclock.

I put a new 3500+ and it wouldnt work, brand new from local store.

It would not post.

I put in a used 3200+ and WHAM it fired up.

Do you think I should try the new 3500 now or do you think if it didnt work before it most likley wont work if I try again?

So, question remains, does a mobo sometimes have to hit post before its reset and similar cpu can be reinstalled?

sound very silly I know but I was just curious

were both 3500+s the same core or could it be that the new 1 was a Venice, the older was a Newcastle/Winchester & you had an old BIOS without Rev. E support?
