Hi there

I just completed a new build how ever Im having issues getting this machine working .... my specs are in Sig and im running Vista 32 SP1


I really am close to smashing this pc up lol! I had issues with sound popping and cracking, So I Rma'd the xfi titanium thinking it was the old creative+vista issue and got a refund, much to my dissapointment I had the same cracking and popping using the onboard sound, so as a test i removed video card drivers, after a reboot the sound was then fine but obviously i had no video capability!!!! so I removed the video card and moved it to the other 16x slot installed the drivers and everthing was fine ... no popping or cracking, well today my new SC turnt up, so I disabled the onboard sound again and fitted the xfi prelude, problem is no matter what pci slot I put the card in it causes the video card to play up, everything seems fine untill I get just before the welcome screen, all of a sudden the GTX280 green LED turns red and i get a No signal message on my lcd ... remove the SC and everything boots fine ... please please somebody help
