Hi, I would like to confirm if you do a system restore successfully. If not, I suggest you start System Restore from a command prompt: Start System Restore from a command prompt If this issue persists, please try to use SFC command in Safe Mode with Command Prompt to check how it works: How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7 Hope it helps.

There are various steps to manually rectify the black screen error such as rebooting the system, cleaning up the registry files and running antivirus program. But these steps might not set the system right and may land the user in trouble if the procedure is not properly followed. The system may also be completely damaged due to corruption of the important files and other settings. Thus, it is highly recommended to seek the help of computer experts.

i tried the sfc scan and it detected that some files were corrrupted and could'nt be replaced and when i wrote the next command on likje"cannot find member file it went into a state expecting some inputs.but ut did,nt showed any file name (which was supposed to be corrupted) so what i should do neext
