While doing all these things i had to reboot several times, and this took forever. Eventually the machine would not restart. It would get to the bit where it tries to boot from CD (there was no CD in the drive and im sure it wasnt trying to boot from the CD) and it said disk read error and asked me to ctrl-alt-del to restart (also there was a very audible click from what i think was the hard drive). This happened several times.
Eventually i got further and booted with the last known good configuration and am using the machine to write this. The CPU usage seems to be calmer but starting windows still takes forever (and im scared to shut down now )
Any ideas what it could be? thanks for any help in advance.
(something i have noticed that is strange is when i go into my system properties from control panel it doesnt tell me about my processor anymore. It used to say Intel 2.6ghz now it only says 1.9gb RAM. not sure if it means anything but i thought it worth mentioning)
