I used my HP system restore. My problem is I cant access secure websites, download anything, run firefox, pretty much anything. I keep getting errors that only an administrator could fix. I have no windows cd. My current hd is 30gigs with 21 used up. I would like to upgrade to a bigger hard drive. I would also like to purchase a windows XP cd so I dont run into problems like this in the future. I dont feel comfortable doing this on my own, so I have a few questions. 1. Should I keep my old hd as a backup? 2. What kind of hd should I buy? I dont play games, basically just use the net and crap. 3. Do i need to buy a new windows cd or should I just have a professional install it for me with my new hard drive? Please dont flame. I porked myself doing a system restore for what was probably an easy fix. Now I just want it fixed right and it seems like the right time for an upgrade anyway. I believe I only have 250mg of ram also. Any suggestions or a point in the right direction is very much appreciated.
