Well here's the problem, last night I was trying to tweak my dsl internet connection with
a DSL Tweaks website GUIDE.(nothing I haven't done before) so I went to restart my computer
so the settings would go into effect. The website said the program I was using wasn't installed
into my computer but it changes the registry around. So my computer booted as it normally does until
it came to the logg-in SCREEN, my Username was already in there so I went to type in my Password and it was
as if my keyboard/mouse froze up and I was unable to type anything, or move my mouse pointer around. I turned off
my PC and started it back up again, and I saw that when I got to my boot screen my mouse still works and the pointer
moves around, but as soon as I hit a button on the keyboard they both stop working... When the comp. boots up I can get into
my set-up menu by hitting F1 and do some type of restore by hitting F10, so I entered the setup menu and set everything there to
default and hit save changes and the same thing kept happening. I can't enter Safe Mode, because it still wont let me get through the
Logg-in.
I have a HP Pavilion, with Win Xp
2.6GHz P.4 processor
512MB RAM
80GB HD

If anyone could give any suggestions on what I could do, I would greatly appreciate it, thanks.1. Before Windows XP LOADS, press F8
2. Select Last known good configuration and press Enter.I did that before, and it still pops up the logg-in screen, where i have to logg-in, and i can't. Try the FOLLOWING:
