Hi, can anyone help me. I am having the problem in my Windows 7 which I have installed just a few weeks ago. Now when I turn on my computer it works for some time and then suddenly shows me the message that "Windows has encountered a critical issue...system will be restarted" After this message windows waits for some time and then suddenly gets rebooted. What is the reason behind this? Can anyone help me in this context? Please help me.
