I have a Gtx 260 gfx card and have been trying to install the Nvidia 310.70 drivers. Whenever I try and run the .exe i receive an error: 7-zip Data Error. I have been trying to trouble shoot and am not sure if it is a hardware issue or a ISP connection issue. I have also tried to install Java (offline version) and get a data1.cab error. Its starting to get frustrating and I cannot system restore as I just did a completely fresh install not more than an hour ago. Not sure what to do, if anyone can help me work through this problem that would be great.
