Somehow my internet stopped working. I am having tons of pending emails in my inbox. I am not able to connect. I had contacted my ISP for the problem. He said to run system restore. According to him everything is fine from his side by my pc is not able to connect to internet. I am not able to find the cause here. I tried to check the manual settings but still it fails to work. It is getting complicated now. I am planing to run factory restore here so that I can get my old settings back.
