Welcome to WebmasterWorld!
Sounds like your ISP may have DNS problems, but it's also possible that you've picked up a virus or browser hijacker. You didn't provide much information about error messages or what kind of system you're on, but maybe this will help:

Second, delete everything in your temp folder, it may be hidden so you will need to un-hide them via the foler options. In XP it is in Documents and settings/your_user_name/local settings/temp
Third, update and run spybot and adaware.
Good luck, it took me 3 hours to clean a friends machine after an "infection" like that, and I call it an infection because it is more like a virus than spyware, it's just at some point you agreed to install it... Be wary of the word "free"
The best thing to do is RTFP (read the fine print). Know what is going into your system and stay away from spammy websites. Update and run spybot as religously as you run your anti-virus scans, you are running anti-virus scans aren't you.....
If you can't download these spyware/hijacker removers on your infected machine, how about using another computer to download them and then write them to a CD, CD/RW, or even a USB memory stick for use on yur machine? If you followed all of the points that have been posted above and are still having no luck, then that's one more possible solution before you revert to reinstalling Windows.

These programs are getting really nasty and more difficult to evade so again, be careful what you download and what terms you agree to when installing.
