Use the site Straffo posted its very good and the one i use if i get any problems with my KT7-Raid.
Btw if you dont have yet then first thing get at least a 300w power supply.
And i am very close to you nearly on your doorstep

I dont know what it is with this blue flicker bug but i have never had it with any of my 3 Nvidia cards to date.
TNT Ultra
GEF256 Ultra
GEF2 GTS Ultra
So i really cant comment on that but this is one piece of advice that could cure all your boot problems as it relates specifically to your graphic card,
Why does my system not boot with the Asus V7700 AGP Card?
This problem can normally be resolved by raising the I/O voltage in the BIOS to 3.4v and/or raising the AGP Driving Strength to EA in the Advanced Chipset Features of the BIOS. See the ABIT FAE advice.
Seems you bought the most problematic of all the Nvidia GTS boards when used with the KT7.
