I need the user guide board K8N neo3

Yes, you just need to install it into the white Pci-E slot. It should work fine.

Here are the drivers.
Unzip the files before you install

And the manual:

Good luck

Better to get a new power supply - they are only about $40

Asuming the fan itself has failed, buy an aftermarket fan. They are usually self-adhesive.

u can change

I believe this web page will give you what you want:

Did you reset the cmos on board first?

How long do you wait before you determine it is locked up? Vista uses minimum graphics to facilitate a faster install. It may seem like nothing is going on when Vista is loading in the background. If it is locking up try a reinstall. Are you upgrading or going a new install?
