<issue fixed and edited out as a result>
It seems had to pull the nic out again and put back inside don't ask me why dunno!

final questions remain:

Hello,

Not sure where to start but put together a motherboard that was not in use.

When first booting it said "cmos crc checksum error" or something like that. "loading safe defaults". Ok, reprogram the error is now gone.




P.S: what was that error anyway and always appears when short the pins? That is clearing the cmos will bring it back everytime. It disappears until next reprogram.

P.P.S:

At first it complained also of unknown processor 12000 mhz. So thought that might be the issue. So flashed the motherboard from dos. Now it says: AMD duron with correct speed. But it does not fix the problem.

Try replacing your cmos battery.

Thanks for the reply sounds it is possible the board was off for few years.
