Question

Win7 boot failue (black screen) does not load AFD. SYS

Sep 9, 2015 3:11AM PDT

Out of the blue my laptop will not boot windows 7. It is a Hp 4730s with win home premium 32bit installed (it was a mix up and as a consequence it got a 32 bit).

I've tried disabling everything system non essential in msconfig and updated the bios without success. Right before the OS should load, right after the win logo disappears a black screen persist.

Now i can boot it in safe mode, and i've enabled boot loging, the problem seems to be AFD.SYS related. If anyone has a clue what the problem is, please help.

The bootlog:
Bootlog_dropbox

Compare the file with any other Windows 7 32 bit system (version and size). Can you rename it (and back of course), can you scan it with your antivirus, can you copy it?
If necessary, replace it with a good version. You might need to boot into Linux to be able to get that from your USB-stick.

But first I would try sfc /scannow from the command prompt to see if that finds anything wrong.

It's not sure at all that the issue is a corrupted file, but it's possible and not too difficult to check. If it's not that there's more involved. Then we try system restore and a clean install of Windows.

Thank you for the suggestions.

tryed sfc /scannow it completed, didn't help.

Replaced afd.sys with an old version of it which is already on the computer ( the date of creation is 2010) didn't help.

I'm starting to think that the afd.sys file isn't the cause of the problem but a simptom... something else is wrong and as a consequence the system cannot load afd.sys.

That's my idea also. That's why I wrote: hen we try system restore and a clean install of Windows.
Make a good backup of your files first!

You changed things in msconfig BEFORE the problem happened and something you turned off broke it. Do you remember what all you stopped while using msconfig?

Sorry I wrote the first post quite stupidly, events are not in a chronological order, I did all of the above after the problem had occurred, I did it all in safe mode.
