Please help me regarding that. Thanks.
Are you able to get into safe mode ? at start up hit f8 key, then choose (last good configuration) or choose safe mode..If you can get into safe mode,go into help and choose system restore..
Have you made any changes to your hardware, BIOS settings or installed a program in Windows before the problem started to happen?
In my opinion the best way to solve your problem is to start again and install your operating system from scratch. This isn't the easiest way, but it's sure to get the most positive results.
