Fatal1ty F-I90HD Causing Crashing

[Houghsx]

Hello,

I have purchased the Fatal1ty F-I90HD, put it all together and got it up and running. However, when I try and look at a photo or video is crashes the system. If I try and set Vista to Areo or run the system performance test it locks up.
It seems that when I ask to use certain functions of the GPU it kills my system. I have also tried installing XP but as soon as I install the graphics drivers it locks the system up totally, I cant go into the Cat control Centre as this also locks my PC
I have tried updating the BIOS and drivers for the system but get the same problems time after time.
This is my first Abit M/B and the experience isnt to good.
Any ideas?

System Details:

CPU - Core Duo E6750 (Arctic Pro Cooler)
M/B - Fatal1ty F-I90HD
Mem - Corsair TwinX DDR2 XMS2 Dominator, PC2-8500 (1066)
PSU - Tagan TG480 (480w)

check the voltage set for your RAM - it will probably be at the JEDEC 1.8V but requires more for rated speed operation.

I did change it when I set it all up so it's not that but thanks for the reply.
