Random Checkerd Screen on booting

Ok this is a weird one. All my hardware checks out. Mem check Cpu check dxdiag etc.
My build
P6T Motherboard
I7 920 quad cpu
1000 watt P/S
12 Gigs DDR 3 OCZ Gold
GTX 280 1 Gig Ram came overclocked
Sound Blaster Fatality Pro
HPw2207h
1 Terrabyte USB (Backup HD)
1.5 Terrabyte sata (main hd Win 7 Ultimate 64)
DVD RW CD rom
320 HD IDE (XP Pro)

Had some weird checkerd color bule/green yellow/orange upon booting up to Win7. Safe Mode is fine and so is Win Xp Pro.
Sometimes it will take 3 or 4 boots safe mode to regular before I can get into Win 7

Have done a re-install and all latest drivers. The only thing I can think of is that 1st time I loaded HD I used my Drivers for the Mother board. 2nd install I just reinstalled windows 7 the only driver I loaded for the motherboard was the one for the onboard lan card.
