I am the regular user of the desktop. It is at my home. I have purchased the new HD 5870 SOC for my pc. And then try to install the driver in the in my system. But I get the error in that procedure. I cant understand why it do so. Then I was tried to refresh my card with atiflash then also I cannot get the desired output. The error comes again this time also. Actually when I am trying to do installation I get the error message of "ADAPTER NOT FOUND". And the process will stop automatically. I also check out my hardware it is also fine. I don’t get the idea to solve this problem. Can anyone give me some suggestion to solve this problem? Please help me out.
