Last night I shut down my laptop normally and it was working fine. Today when I tried to start my laptop it shows vaio screen than blank screen with curser after it goes black than again vaio screen appears and all sequences repeat continuously. I don't no what happened suddenly and how it can be resolved.

I bought it in sept. 2011. SONY model: PCG-71811W, PRODUCT NAME: VPCEH25EN.

 

No falling or any bumbs .

 

No beeping or any sounds, just VAIO screen for second then screen with courser for second and black screen for second and the whole process continuous again & again without any beeping or sound. I tried to reboot it by removing battery and then pressing 'ON ' button for 30-45 seconds and try to restart after placing the battery but not succeeded.

NK Sharma,

 

When you switch ON your Laptop, start tapping the "F8" key to get "Windows Advanced Options"( if boot menu appears, press "Esc" key and
keep tapping the F8 key)

Select the option "Last Known Good Configuration"

Hopefully have a system restore point before this issue occurred, if not do you have a Windows Operating disk ?
