Run the System File Checker to scan your system for corrupt or missing system files. Windows will replace missing/corrupt system files.

1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.

2. Click Continue or supply Administrator credentials if prompted.

3. In the Command Prompt window type the following, and press Enter:

sfc /scannow

Note the gap... it should be there.

4. You should see the following on-screen messages:

Beginning the system scan. This process will take some time.

Beginning verification phase of system scan.

Verification % complete.

5. Once the scan has completed you will receive an onscreen message resembling one of the following:

…found no integrity violations

…found corruption but repaired it

…found corruption that it could not repair

Please reply back here with the completion message that you received.

Emeraldnzl,
I spent the ADWCleaner again and this time it worked. The SFC has put some system files back, but it restarted and did not give me the log.
In C: this log only has the first time the computer crashed:

Good Night, Emeraldnzl,

Catch you tomorrow.

The Windows Resource Protection found corrupt files but can not fix some of them.

Depends how important they are as to whether they are causing your problems.

You may need to run SFC a few times for it to completely repair corrupt files.

See here

You can go to the link below for information on analyzing the CBS log:

See what you think, if after running SFC again you still have problems perhaps we could have a look at the log. The main thing is to fix corrupt/lost system files.

You might also do this:

Go here for information on how to run Chkdsk in Windows 7


Whatever you do come back and tell me how your got on and if there has been any change in your computer.

Emeraldnzl Hello, you okay?
Sorry, I had to leave a little bit.
Look, I CHKDSK first time (with the option to fix system errors and look for bad sectors).
Then I spent the SFC / SCANNOW 4 TIMES (CD through windows 7, with the instruction: sfc / scannow / offbootdir = x: \ / offwindir = x: \ windows) and log end was always the same: found corrupt files but not can fix them.
There hove changes on the computer. Still problems with Internet Explorer and the black screen at startup.

Still problems with Internet Explorer

You might try using Mr Fixit see How to reset Internet Explorer

Tell me if that makes a difference.

the black screen at startup.

Is that just for a short time or something longer? Does it have a message?
