Hi everyone, My old Leadtec Geforce TI4600 died recently and I've replaced it with a Gigabyte 7600 GS. I'm having all sorts of problems installing the new drivers. If I use the installation disc I get 'Invalid Data' at the end of the installation. If I download the latest drivers and install them, when my PC reboots it's as if nothing has been installed and my pc prompts me to go through the same installation routine?! I removed all the old drivers before hand. I had heard of some issue with old Leadtec products and registry security settings - not sure if that's the issue. My motherboard is an Asus a7v8x with a via kt400 chipset. Any ideas chaps? Thanks in advance.
