Dell OptiPlex 755 Bios Update - Skips rows in BIOS and double characters when booting into DOS

I updated from A19 to A22 and even back down to A19 on my OptiPlex 755...  Now it skips lines when I try to change settings in BIOS or when I boot to a DOS USB drive it double types letters.  Never happened before until after this update.  I ran into this a few years ago and I know its a simple fix, but I can't seem to remember what I did.  It does not happen in Windows 7.  I've swapped the keyboard, etc.

Any help would be greatly appreciated!

Thanks!

Remove Cmos Battery.  UNPLUG POWER.  PRESS POWER ON.  Discharge.  Put battery back.

Plug back in.  If there is still wierd display some of the ram may need to be re seated or replaced.
