First Of all i'll list down the configuration of my pc so anyone can get a clear idea about my problem. Processor : Intel Pentium Dual Core (1.8 Ghz) RAM : 1GB HDD : 160GB So my problem is as soon as i connect to the internet my pc acts likes a pentium 1 PC.Sometimes it stucks as soon as i connect.Please don't suggest to format and re-install my windows XP cause i want a better solution than that. One of my friends told me that this may happen because of corrupted registry. What do you guys recommend.I know there are lot of experts here.
