Under Windows 7 Home |Premium 64-bit OS, my PC had an NVidia GTX260 Maxcore 55 Graphics Card, all working perfectly. Then I decided (stupidly) that I wanted to set up MS Flight Simulator 10 with 4 screens - a bad mistake! I tried and tried to get the right connections with the NVidia card, but in the end, NVidia told me that it was impossible with that card.
I then bought an NVidia GTX610, and after many hours of trying to get that to work (I had been assured that it would), I was once again told by the NVidia man that this also would not work. What would, I asked. He tentatively suggested another Nvida card, but strongly preferred the AMD range, mentioning the HD7950. Just for once, it had 4 connectors to match the number of screens that I wanted.
I bought a brand new Gigabyte AMDHD7950 card and installed it. My computer, previously working well, would not even start up with the POST, let along the rest of the BIOS. The suppliers suggested that perhaps my PSU was not pushing out enough wattage, so I purchased a 900W PSU, but of the cheaper variety. The graphics card was returned to the supplier for testing and found to be okay. I exchanged the PSU for a 650W model, but of higher quality, and it also had all the right connectors without adapting cables to give the required format. By the way, the HD7950 has a Power requirement of a 6-pin supply AND an 8-pin supply - the new PSU had both.
I reinstalled the card into my PC and .......... it still would not even start up the POST. I put the old card back in, and it worked just fine.
My question is....WHAT AM I DOING WRONG? WHY WON'T MY PC WORK ANYMORE? If anyone out there has any ideas, then I would be very pleased to hear from you. Because of the number of times that I have swopped the cards over, I don't think it is a connection problem. By the way, I have also placed a metal bridge over the 2 pins to replace the CMOS with the makers' defaults, but that doesn't work either. All I get now is a total blank screen, except when I have my old card in place.
I have tried to speak to Gigabyte Technical Support but all I got was a very terse man who told me that he knew nothing about this item, and therefore could not help. He than told me to go to the Gigabyte website and sort out my problem from there. It was then that I happened to mention that without my computer starting up, that would be rather difficult. No Response (of any use, anyway).
