I have recently installed the Windows 7 operating system in my Compaq desktop by removing Windows XP. Actually, I am facing a very unusual problem ever since I have installed this new operating system. The situation is that Windows 7 64-bit freezes on Yahoo login or Yahoo notifications. I am not able to understand why this is happening. There were no such issues when I was working with the older operating system. Please help me with all possible suggestions to eradicate this situation.
