For the last 6 months now my computer has been taking longer and longer to load windows. I have had several error messages appear both on start up and shut down. On shut down I always get messages saying certain programs haven't shut down properly and also on start up I get messages saying my computer has just recovered from a serious error.

Now on start up I get this error come up and when I press don't send it keeps popping up for about 20 mins and during that time I have no start menu, tool bar or icons and can only get online through my error message. Microsoft have never heard of it and it is driving me crazy. I downloaded registry mechanic and that didn't help, also I couldn't find the file on my computer.
Please please help someone as It really is getting worse all the time and I don't want to format my hard drive as it would take forever for me to set it all up again.

Thanks
Regards
