Hi, I've got a Dell Inspiron 1545 running on Windows 7 (not sure which one). I was working on it and it completely froze up about a week ago. After trying CTRL - ALT - DEL i was given a message to say that it wasn't responding and that i should switch the computer off manually. I did this and went to turn it back on but all it came up with was 'Windows is loading files' i left it to load however it was just repeating this same process over and over without any progress. I then tried doing a Diagnostics Test where it kept telling me there was an error and then it would continue the text any longer. After this failed i tried to boot up from the Windows 7 disc that came with the laptop. First i tried the repair option, however the laptop sat there for about 4 hours on the same screen not doing anything. I then tried to reinstall Windows 7 and this wouldn't work either, the screen just said 'Windows is starting up' or something similar. I have not backed up my laptop and really don't want to loose what is on there however i realise i might. Most of all i would just like it working again as am in desperate need due to being at University.
