Hi All, I have Sony Vaio which is just 1 yr old. About a week before, I installed the latest updates windows 7. When I started the windows, I was able to log into the windows. But then, the system was very slow. So, I turned down the laptop. After that, a message appeared "A disk error occurred. Press Alt+Ctrl+Del". When I press it, the same message appeared. I tried to go from the safe mode and there is a blank scree with a cursor. I cannot do anything with the cursor. No right click. No task bar and even tried pressing shift 5 times. Every step leads me to the same screen. I even tried to get to the vaio recovery for setting it into the default factory settings. I searched the internet for a long time but couldn't find the solution. Please help !!!!
