I have a handful of fairly serious problems so please bare with me!
I am running windows 7 and recently suffered the "setting up personalized settings" failure where my computer would only load this page andnothing else. At first I believed this to be a virus (where as I now believe it to be a windows update, as it happened to my partners computer and was quickly resolved with another update), and was desperate to clear it so blitzed it with antivirus scans (malware bytes, spyware s&d) and attempts to clear it. Eventually, the problem ended HOWEVER my desktop now loads as normal but is cripplingly slow (it takes roughly 7 hours for me to do something that would usually take 15 minutes), and now am also unnable to load safe mode due to a crash on loading CLASSPNP.SYS. I believe im my haste to fix it i have deleted some key system file. I have attempted to run /SCANNOW in the command pannel to check and fix for errors however have only got this to run once and took roughly 24 hours to get to 37% where it crashed. In desperation i tried to install ubuntu but encountered an error in installation. Sometimes when shutting down i get an error about windows not being able to run command prompt as i am running too many 32 bit programs. On top of this, my laptops fan doesnt seem to be running!
Please advise me as to what i should do, re-install windows? press on with ubuntu? throw the laptop in the bin?! thanks
