I'm running win 7 Ultimate 32 Bit, which has been fine up to a few days ago when on start up reaching the desktop I started getting a window saying "Windows has encountered a critical problem and will restart automatically in one minute." it would then restart and continually loop this way. I booted to safe mode and had no restart message, so was able to run a virus scan using Microsoft security essentials, however if I booted to safe mode with networking the restart window would show again. I have looked for the Gbp Service, which I was advised might be causing the problem, but cannot find this in services running. However, I have found that by discounting the internet, the restart issue does not show, but as soon as I connect to the internet, it pops up and the system restarts. It has ben suggested to me that I try a system restore and if that doesn't work a repair installation. System restore failed on multiple restore points. So my main question is with a repair Installation: as I cannot connect to the internet, will I have a problem with the repair installation not being able to get the latest updates for the installation process? Many thanks Happy.
