I have a Toshiba Satellite L500-1XD with Windows 7, which is just 4 or 5 months old. Yesterday when I turned it on, my user profile had effectively broken - it just couldn't be loaded. I took it in to the IT service at my university and he helped me to apply the recommended fix for this from Microsoft, but it didn't fully work and Windows 7 was now full of bugs.
So I then ran the system recovery discs that I made when I first got the laptop but something's gone wrong - it went through the whole process, but as it tries to set Windows up for first-time use, it suddenly shuts down and reboots. This process just keeps on repeating. I tried shutting it down for a few minutes by using the power button to see if that would change anything, but when I turned it on again, it still kept doing the same thing.
Does anyone know what I should do next? I can do basic admin tasks on a computer but this is way out of my area of knowledge. I'm in the final stages of writing a thesis which is overdue and am desperate to fix this immediately - any help much appreciated!
