System Keeps Rebooting GA-8IK1100

Hi,

I just put in a new mobo and cpu in my system. I'll give the specs below.
When I boot up, it POSTs, properly detects my hard drives and cd-roms and
then it goes to a prompt that tells me Windows did not properly load on the
previous attempt. It asks me to select from normally starting Windows, or
Safe Mode, or Safe Mode with Command Prompt or Safe Mood with Network
Support. No matter which I select, the systems just reboots and we repeat
this process over and over. What can be the problem? I have tried:
1. unhooking all IDE devices but my primary hard drive
2. putting the primary HD jumper to Master, Cable Select and none
3. using a different IDE cable

My systems specs a

Gigabyte mobo, GA-81k1100
P4 2.8 w/hyper threading
1 gig of memory (PC2700) installed in two channels
WD Caviar 80 GB HD - master
WD 40 GB HD - slave
FDD
Sony DVD burner
Sony cd-rom
Windows XP Professional
Zoom 56K modem
ATI Radeon 9200 128 mg video card

I would appreciate any suggestions to get this baby up and running again!
Thanks!!
Sally
