Having a windows 7 compatibly HP laptop, which was working fine till yesterday, suddenly there is problem occurred in my laptop to run the windows environment. I checked all the setting with the setting which I configured in my machine, but found no fault. I also tried to run the machine in safe mode there the same happens, what should I do to solve the problem why this type of problem occurs, I am not able to run the windows 7 in both safe and the normal mode. i searched everywhere for the solution, but found nothing which will fix this issue, so i am here looking for any solution for this. Is there anyone having any solution for this? Any information about this will be appreciated.
