Hello All, it has been some time since I was here in the forum. Computer problems !! And now I may have created more !! Hoping for some help.? Just got my HP Pavilion zv5000 back from the tech shop. New processor AMD 64 3200+ installed . The operating system is MW XP Home Edition Version 2002 Service Pack 2 installed as well. I updated Norton, Zone Alarm, Windows. Next I went to clean up the c drive. Did notice a pile of files. checked some out but didnt notice anything out of the ordinary. The cleaning stopped and said that some files required for Windows would be deleted and that I should retry or insert the MW disc. Inserted the disk but i cancelled the operation. Now, how do I find out if I have indeed deleted any necessary files? I am afraid to turn of the laptop cause it is working right now !!!!! Any help to a frustrated and not so computer savy chick would be appreciated !!
