Powers up fine, soon as I put an ethernet cable into it - it just powers off? There must be some kind of conflict.


It was working fine before.

Before what? Did you update or install anything? Make any changes in the BIOS? Are you sure it's powering off, no fans spinning? Look in Device Manager and expand the +'s. Look for any yellow exclamation points. Also check the Event Viewer:

Check the ethernet cable (maybe try another one?).
Check the little wires inside the port to see if they're bent.

Sorry it was after I reset the bios by removing the cmos chip the problem started - so I am guessing I need to change a setting in the bios back to its orignal value.

Any ideas?

(I've tried different cables)

Do you mean you removed the BIOS BATTERY to reset the BIOS? That is the normal way to reset the BIOS, or moving the BIOS jumper. Removing the chip won't do that and you have the possibility of putting it back in backwards or bending some pins. I doubt you did that, because it probably wouldn't even boot. Boot back into the BIOS and select Restore System Defaults, or words to that effect, Save Changes, and Exit.

FWIW: Removing the CMOS battery...accomplishes the same thing as...shorting the CMOS jumper. You don't have to do both.
