a big Hi for everyone.

I have a problem with a driver in a compaq pc, the driver is a video driver sis760, the problem is that it freezes the video after like about a minute after the system starts , the thing is that I formated the hard drive and installed a new system and thats when the driver started to fail, I'm using a driver from a backup copy I made from the original system .

in the original system that came with the pc I had no problem at all with the same driver
