Help!!! new Comp wont boot!!!

ok just put together my setup it consists of
-EVGA x58 sli
- i7 920
-thermaltake tr2 430 watt
- crucial 3gig ddr 3 tripple channel ram
- evga ge force 9500 gt pie-e 2.0
- sony 20x dvr rw
- 80 gig seagate hard drive Ide to sata converter

Ok not sure if this is the problem but i am using my old harddrive with windows xp. I also had to get an ide to sata converter. I turn on the powersupply press the power button and i get to bios. What happens is the comp boots up to the windows loading copyright screen then flashes blue screen with white wording then resets./?????? Im sure I am missing something very simple. All i tweaked on the bios was turning on the pci express option..

I purchased the cheap ram powersupply and video card because i am saving up for the good stuff.

O also i did not apply any heatsink paste because i thought the stock fan came with some already on it. Looks like three greay strips on the bottom of cpu fan cooler. I checked temp and it was around 45C so dont think that was the problem.
