So, I bought an ATI Radeon 6790 the other day and it just came to me. I also got a new OCZ ZS-Series (I think its called that) 550 Watt power supply and it is working fine so I know any issues would not have to do with the power supply.
So, Here is my problem. After a lot of trouble I managed to install the 6790 into the PCI-express slot or whatever its called on my motherboard. What I have done, over and over and over again, is, boot up, disable my onboard graphics (which is Nvidia GeForce 9100) then I inserted my cd and installed everything onto my computer. However, after I disable the onboard graphics I will boot up my computer and everything, no problemo. But it comes back into a very low resolution and my Radeon doesn't show up in Device Manager, when I go to 'screen resolution' (btw I'm using Windows 7 64-bit) the display just says 'Default Monitor ON'. If I go into Catalyst Control Centre (the program that came with my driver that installed everything) if i try to adjust any settings, the following comes up and says that 'ATI's Display driver is not currently running'. I thought the driver would have been installed already. How do I get it running?
Also, other than my video card being plugged into the PCI-Express slot, there is nothing else connecting it to any part of my computer except to my power supply (since it requires a power supply connection). Do I somehow need to hook it up to my monitor? I've tried everything. I also have tried going into BIOS to change some driver settings but my BIOS on my computer (HP p6210y, AMD Athlon II X4 620 quad-core) has hardly any settings and doesnt have any settings at all relating to drivers or my graphics card or anything. I have no clue what to do.
PLEASE HELP MEEE
