I have an HP p6310f running windows 7 and recently I installed a new mother and a second internal HD. I installed the additional HD because I did not purchase the motherboard from HP( but it is the model as the one that came with the computer)I couldnt install the oringinal harddrive without losing data on it I didnt want to lose the data on original HD thats the reason for the new HD. Computer is running fine, but in the device manager in other devices it say the Coprocessor driver not installed(code 28). Where would I find the driver for this It is an AMD Anthlon llx4? I went to their web site and did not know which I was suppose to Dl. Any help in this matter is truely appreciated. Thank you
