Wow...I can guess that you're loaded with viruses that load like drivers. We should be able to fix it but I first need your ComboFix log if it's possible for you to run a scan.
Download and Run ComboFix
If you already have Combofix, please delete this copy and download it again as it's being updated regularly.

• Download this file from one of the three below listed places :
  
  http://download.bleepingcomputer.com/sUBs/ComboFix.exe
  http://www.forospyware.com/sUBs/ComboFix.exe
  http://subs.geekstogo.com/ComboFix.exe
  
• Then double click combofix.exe & follow the prompts.
• When finished, it shall produce a log for you. Post that log in your next reply

Note: Do not mouseclick combofix's window whilst it's running. That may cause it to stall

Combofix should never take more that 20 minutes including the reboot if malware is detected.
If it does, open Task Manager then Processes tab (press ctrl, alt and del at the same time) and end any processes of findstr, find, sed or swreg, then combofix should continue.
If that happened we want to know, and also what process you had to end.

Sorry, but all that can't be done now: I have already formatted and reinstalled XP.

I just formatted C:\ and reinstalled XP; then I copied back the boot.ini file that I taken from C:\ earlier, and pasted it back to the new C:\, and it detected one OS: I have a total of three OS: XP Pro in C:, XP Pro in D: (as a precaution, for times like these, when the first XP goes bust), and Ubuntu in E: (which I hardly ever run; I installed it to learn Linux, but haven't begun yet). When I copied the boot.ini file back to C:, it would detect the D:\ XP, but not Ubuntu; then I copied "wubildr" and "wubildr.mbr" to the root C:\, and now all the two previous OS are also booting fine.

I've just used DriveImage XML to make an image of C:\; and I have made a sort of boot disk with P E Builder; I booted from the CD with P E Builder, and found that everything is working, I could even run Mozilla, but the problem is the username and password are not saved in the modem, they are in the computer, and that thing vanished with the previous OS, and I didn't know how to make a new one where I could type in the username and password, so I couldn't connect at that time.

Now, I have to install Dragon Naturally Speaking 9 again; hope nothing goes wrong this time...
