Went to restart my XP earlier (ISP changed my IP addy and told me it wouldnt take until I rebooted) and it just kept rebooting over and over - even when given the options to restart normally (which i tried), last known settings (which I also tried), safemode (which stalled it and I couldn't do anything except hit the cold-restart button). On the next series of self-imposed restarts I chose safemode with networking (whatever the heck THAT is) and FINALLY it stopped at a blue screen to tell me WHAT the problem was... ....something about my BIOS not being fully ACPI compliant, and to go to harware-update.com to get one (one what??) or call my vendor (which I don't know anything about because my mother gave me the computer just before she passed and I don't know where it came from originally-other than another province). I know a *bit* about computers but not enough to go messing around with hardware. The closest I come to that is trying to fix viruses with floppies. I did an internet search and am terrified that I now have to do some sort of registry modification or repair or such. I have not tried doing anything with that computer since - the blue screen is still there. Before I got that message it simply would NOT let me just power off...and I am worried that if it WILL do anything next I will mess it all up more by trying to reboot again etc....AND I am worried that if I cut off the main power I will lose my wireless connection for THIS computer (my only hope of communication to repair the other one) and that with the other computer problem plus the new IP thing both computers will then be messed up. What can/should I do next - if anyone might know? I think I might need to take it "into the shop" but in the meantime is there a way to disconnect it that it won't affect the wireless thing for the second computer? The one thats messed up is the MAIN computer that the modem is set up on. I know I probably sound like someone who shouldn't even have a computer. If anyone has any suggestions for ANY of this I am all ears! Thank you in advance for your attempts to help.
