I've had my PC for nearly five years and haven't had major problems except that it is getting slower...and slower......and slower. Takes about 10-15 minutes to boot, and a considerable amount of time to process if several programs are running at once. I eradicated all unnecessary programs when first bought (i.e. AOL, games, Yahoo, etc, etc.) I have to report that since going throug the 8 steps and getting rid of cookies and temp files there is improvement. I use Firefox only for web browsing and do have online banking, passwords, etc. I'll reformat/reinstall the system if need be. I use the computer for web, papers, taxes, music, video editing, image archiving, watch movies--it's pretty much the catch-all. Everything is backed-up on external harddrive. I have never defragmented though I imagine it may be needed. Any other info I missed? Thank you for any advice you may give. edit: oh yes, and programs crash often if I do not allow the comp. enough time to "think." Is that a reiteration of above?
