Go into the BIOS and set the system clock... The checksum error should go away. When you reset the CMOS it clears BIOS to defaults. You lose your system clock, it gets pissed at you because it wants to know the time.

If you put in a new Mobo you are going to have top do a windows Repair at least, a full clean install would be best. If all else fails you may have to wipe the disk completely and start over. I have had a couple of cases where I had to do this. Free>http://www.killdisk.com/ If you use this you have to run Fdisk and reformat
