Oh the joys of school holidays, grandson really caused problems on his computer.

ASUS Eeetop ET AGT B090. Windows 7 Home 64(ww)

Tells us Boot critical file ‘ci.dll’ is corrupt. tried to paste good copy of file but asks me to log on as administrator which I am.

Unable to log into OS either normally or Safe Mode Can only log in using f8 and clicking ‘Disable driver signature enforcement’

Tried to get into f9 restore, but seems to freeze with blank screen and coloured dots at the top of screen. Hard drives are ‘C’ ‘D’ and restore is in ‘G’

Is there anything I can do to progress? Any help would be useful.

if nothing critical why not use the factory restore disc

Thanks for quick reply. Unfortunately there is no disk, restore is on the hard drive which I assume is the one marked ‘g’ above, which just ends with blank screen when I press f9

CAn you get to command prompt using F8?

If so type

sfc /scannow

press enter

let windows find and replace corrupt / missing files. when its completed

retry to boot normally.

  1. With system off. Unplug any USB devices including memory/pen drives.

  2. Boot normally. If still problem reboot to Safe mode.

  3. Uninstall last software you installed. (if this software is Windows installer based you will not be able to uninstall it in Safe mode).

  4. Use Msconfig to disable all possible startup programs.

  5. Try a normal boot.

If no joy then try a system restore.

As I stated in the original question: Unable to log into OS either normally or Safe Mode Can only log in using f8 and clicking ‘Disable driver signature enforcement’

Tried to get into f9 restore, but seems to freeze with blank screen and coloured dots at the top of screen. Hard drives are ‘C’ ‘D’ and restore is in ‘G’

Can you create a Win 7 recovery/boot disk from a friend's PC? It needs to be 32 bit or 64 bit , the same as your OS, and use that to try a repair? There's a link here for 64 bit, Recovery/boot disc.

Thaks for all your help I created a Win7 64 recovery disk still no joy.

Is the logging on using ‘Disable driver signature enforcement’ any indication of error

Sorry clutching at straws at the moment and this is only way we can log on

  rdave13 19:32 PM 29 Jul 11

Can you get to the command prompt?

If so have a look here,microsoft support.
