cannot boot or access bios

Hi,
Yesterday I changed my CPU fan, everything went fine, when i went to reboot i got the following error message 'check system health! cpu id...'

I put back the old fan and still the same thing. I cannot go into the bios settings anymore, i'm just stuck on that black screen and cannot do anything. I press delete etc when booting up but nothing happens.. just stuck on this error message but there is no beep alarm...

is my mobbo dead or something?

Thank you

 

What is the make and model of your computer (or if you know it - your motherboard)?
It sounds as though you may have the CPU fan wired up incorrectly. Hopefully we can find a diagram of exactly how it must be wired.

 

hi,

thks for the reply.

It's a gigabyte GA-7va

I've connected the wiring as it was before..? the small 3 pin connector is connected to the same place on the motherboard as it was before (it's written CPU fan)

This manual shows the fan connection on page 13
Check the diagnostic routine on page 82
