BSOD on first build!!!

Hi,

I'm a noobie so bare with me please fellas! Recently i bought an MSi p67A-45 motherboard for my very first build. When i'd installed the hardware on like 4 GB RAM a Sapphire Radeon HD 5770, Antec Kühler Flow heat sink, New WD Caviar Green HDD. I was then advised to install the copy of Windows 7, which i'd bought a year previously. First 2 days were fine then i got the dreaded BSOD. I took my pc, ith new motherboard to Currys/knowhow as i'd bought all the hardware that i'd attached to the from there, thinking it might be hardware related as the first line of the BSOD mentioned it could be hardware related. Anyways, Currys tested all the hardware and told me that it was all working fine and it must be the motherboard. I emailed the company i'd bought the motherboard from but they said it couldn't be the motherboard and it has to be software or driver problem. The thing is it's a new hard drive too so there's no software on it! I'm really frustrated with this and it's put me off building my own again.

Sorry if this has been a bit of a novel but i thought i'd try and explain everything. Any ideas would be very appreciated. Thanks

What does the BSOD say?

A problem has been detected etc etc as usual then disable any anti-virus, disk defragmentation back-up utility, etc etc
Then:

Technical information: ** STOP: 0x000000024(0x00000000001904FB, 0xFFFFFF88003B92D38, FFFFFFF2E2704)

I've just gone into the BIOS and apparently the RAM's fine. I've now tried to re-install Windows 7 and the PC's Saying to reboot and insert the installation CD, done this twice now but the CD is inserted

I have an Intel i5 2500K processor.
