I have an HP All in one pc, windows 7, after and update, then reboot, all i get is a black screen with a white cursor.  I cannot get into system restore, the normal recovery repair doesn't work.  I have scanned for viruses using a boot disk, nothing found.  It has just had Trend Micro IS installed.  I know the easy solution is to do a complete system rebuild but dont really want to do this.

Can you boot into Safe Mode (F8) at startup?

Then select System Restore

or Load Last Known good configuration.

I have tried all of that, unable to boot into safe mode at all,  using the HP repair function to rollback to a restore point, there are no restore points.

After another HP repair itself, the F8 actually brought up the full menu, but sadly nothing worked, still back to the black screen and cursor.

So, Last Know good has not worked, or safe mode?

do you get errors?

No errors, its like safe mode loads, but stops at the cursor.  Unable to open task manager either.

Press f8 while the system is booting (before the windows screen) and select VGA mode.
by doing the following:-

For Windows 7 select:
Enable low-resolution video (640×480)

loosk like an update, as broken something, I'm surprised you cannot get into Safe Mode.

You could try a Repair from DVD.

Chkdsk didn't report any errors.  I have already tried a repair from a DVD.  I wonder if i delete the User.dat file, and see what happens?

the user.dat is the profile for that user.

if the server does not go into safe mode, it's hardware or driver.

Uninstall trend security software. From another computer download trend micro removal tool and copy it to a flash drive.

Boot the computer in safe mode with command prompt -go to flash drive prompt and launch trend micro removal tool.

Can try booting the computer in VGA mode. Also check how many cables are connected to your monitor.

Hi Thanks for the suggestions.

I gave up in the end, backed up the clients data and completed the HP System Recovery process.
