Ive tried all the suggestions about installing the update readiness tool and trying to install vista sp2 with no success. I then turned off my screen saver,thinking maybe it wasnt installing because it kept interfering with the process. I thought I would give it anouther go on trying to install the readiness tool,and success! I then tried to install vista sp2, which was also successful.Although these processes take a little time,you might try that.

Please start a NEW thread of your own, and attach the CheckSUR.log file to your post - also, run the following tests while waiting for a response....



Please run a full CHKDSK and SFC scan....
Click on Start > All Programs > Accessories
Right-click on the Command Prompt entry
Select Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.

At the Command prompt, type
CHKDSK C: /R
and hit the Enter key.

You will be told that the drive is locked,
and the CHKDSK will run at he next boot - hit the Y key, and then reboot.
The CHKDSK will take a few hours depending on the size of the drive, so be patient!
After the CHKDSK has run, Windows should boot normally (possibly after a second auto-reboot) -

then run the SFC.

SFC -System File Checker - Instructions
Click on Start > All Programs > Accessories
Right-click on the Command Prompt entry
Select Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.
At the Command prompt, type
SFC /SCANNOW
and hit the Enter key

Wait for the scan to finish - make a note of any error messages - and then reboot.
Copy the CBS.log file created to your desktop (you can't manipulate it directly) and then compress the copy and attach it to a reply to your new thread.

Post a new MGADiag report with details of any error messages encountered.
