I have a strong feeling your problem is due to a hardware problem or a problem with your ISP (although they claim otherwise). However, I can continue troubleshooting with you if you'd like me to.
If you would like to continue troubleshooting, please download and run hijackthis Do a scan and then save a log. Take the log and ATTACH IT (do not post) to your next post.
We do not like to post hijackthis logs in sections other than the malware forum as we do not want to encourage people to post malware issues in this forum.
I am not looking for malware. I am looking for what programs or combinations of programs might cause this behavior. If I notice any malware, I will redirect you to the malware forum.
If you post a hijackthis log in this forum, several trusted techs will come to your house and eat all of your Ritz crackers, Cheeze Doodals and any sweet pickles you have in your fridge. We will also put our feet up on all of your coffee tables. This is no joke. We'll do it. It's not pretty.
