I was thinking about doing that but have been trying to find other ways or possible solutions as to possible fixes. I've been looking around the net for solutions and have tried the 'last known good configuration' which didn't work. Then I came across a site which a few people seemed to have the same problem as me. They mentioned booting up windows with the cd, going to recovery, then typing in 'cdsystem 32' and then copying userinit.exe and wsaupdater.exe to your computer. I tried that, but that didn't work, even though they've had exactly the same problem. Any ideas with that? Because the last time my machine was working was on Sunday, and it was lagging like hell, so I did a scan with adaware to remove some stuff and since it hasn't logged on. According to microsoft.com they say that a common problem with adaware is that it removes the wsaupdater.exe and then when u try and log on, you can't!!!So I thought my case could have been connected with that, but as I say, I've tried what they said, but to no avail. U think a repair install is the best bet then?Will it return all my internet favourites etc back to it's original state? I've got loads of sites in my favourites that took me ages to find would be gutted if I had to lose all them - as I will be if I lose everything on my machine full stop!!! Oh and by the way, the language was easy to understand lol
