Power Supply problems

Hi guys

I recently upgraded components in my computer and got a GIGABYTE ODIN GT 800 Watt power supply

after installing it then booting then installing the program it comes with, when i load the program it comes up with HARDWARE CONNECT FAILURE

I took it into a computer shop because i couldn't be bothered fixing it but they said it was OK and that it runs fine
they said that it could be a OS problem but i ran the program on a XP and Vista(both 32 bit) computer and that's not it.

I was told that it could be Norton 360 software conflict

Any help would be appreciated

Thanks!
