Windows Vista crashed...Startup Repair won't Launch

original title: Windows Vista crashed...Startup Repair won't Launch..please help.

Hi all.

My laptop screen went black on me this appeared to still be running, but the screen looked as though it was off.

I turned it off and tried to turn it on again. The 'Acer' logo came on as normal, but when the Windows Vista loading screen appeared, there were little green squares on it in lines, vertically down the screen...

Then, it took me to the 'Windows Failed to Start' screen, with the option to do a Startup Repair. (green squares still present).

I tried to Launch it and it just refreshes the counter for the auto launch, and when I choose to Start Windows normally, it just black screens again...

Really struggling here guys - although luckily I backed some of my work up yesterday, so can live with wiping the hard drive if necessary.

ANY help/pointers will be most gratefully received.

Thanks in advance.

Should be in Vista, sorry :(



Try a System Restore back to before this happened. (You may need to do this again after
the disk diagnostics if it passes.)

How to Turn System Restore On or Off in Vista


Check the drive for errors and then run SFC /scannow.

Disk issues can get serious very quickly so I would thoroughly check the drive now and be sure to keep
redundant backups of your important data (use several methods).

Inside Windows - Regular or Safe Mode (repeatedly tap F8 as you boot).

Run checkdisk - schedule it to run at next start and then Apply OK your way out then restart.

How to Run Check Disk at Startup in Vista

Start - type in Search box -  COMMAND   find at top of list -  RIGHT CLICK  -  RUN AS ADMIN

sfc /scannow

How to analyze the log file entries that the Microsoft Windows Resource Checker (SFC.exe) program
generates in Windows Vista cbs.log


These are much more efficient methods to check the disk.

From the Command Prompt of the Recovery Console (if you have one) or from a Vista disk - if you do not
have a Vista disk you can borrow a friend's (it needs to be same 32 or 64 bit and they are not copy protected)
or make one. Also your System maker will sell the physical disks cheap since you already own Windows.

chkdsk /f /r


Space after k and before /  and after f and before /

sfc /scannow


Space after c and before /

This tells you how to access the System Recovery Options and/or from a Vista DVD
