Windows 7: I need HELP - BSOD on start up unless F8 LAST KNOWN GOOD CONFIGURATION

Bottom line - I cannot use this machine unless I F8 and opt for "Last Known Good Configuration"
every time I start up.

BUT what I don't understand is why it doesn't throw up BSOD when using
"Last Known Good Configuration" because it stills starts from scratch (albeit F8).

Your last known good is controlset005. Comparing that with controlset001 reveals an additional avast filter driver in controlset001.

There is also a driver set to start type 0 called aswARdisk

Possibly your Avast updated itself and added this new driver which is causing the problem.


1. Boot up using last known good - then use avast uninstall tool.

Avast Uninstall Utility | Download aswClear for Avast Removal

That might do the job - without having to do any manual registry editing. I don't know how effective their uninstall tool is at scouring dormant controlsets- maybe it will do a great job.



OR

2. If that doesn't work - then you will need to make some registry edits manually:

Boot up using last known good.

Then open regedit and use the find function on controlset001 to remove the extra filter, and also set the start type to 4.

You will need to check the other controlsets ( except 005 which is fine because it works)

You can then unistall avast using their tool.

Hi SIW2

Sorry to trouble again about the same problem.

CAN I ASK THAT YOU READ ALL THIS POST – IT’S NOT JUST A GREAT BIG THANK YOU!

Sorry it has taken such a long time to thank you, but in between still trying to sort out this problem, I have been at the hospital with my wife (she has some serious health issues).

Firstly, my thanks for showing me how to solve the problem.

I followed what you suggested and I couldn’t believe that it worked.

Over the years I’ve warily deleted ‘this and that’ from the Registry stuff like programs to keep windows running/clean up – that are stubborn to remove all traces.

So I was really impressed that you could locate the problems from such a maze of data.

When I rebooted and she started again in regular mode I cannot tell you the relief.

Like many, I have so much on this system. The thought of reinstalling Win 7 and all the Updates from years ago fills me with horror.

UNFORTUNATELY AFTER ALL THAT – I STILL HAVE A MASSIVE PROBLEM

The system is very sluggish – the hard drive light rarely flashes. Google searches take an age.

So when I could, I have been trying to fix these problems.

But with what’s going on with my wife I'm not on the ball.

Stupid I know, but I'm sure I read there is at least one Update from April that needs deleting, that it seems has caused all this nightmare, (from what I've read this is all Microsoft’s fault) but I cannot find which one to uninstall.

I also read MS have released a fix – but can’t find it.

Fast forward to now, early hours 19 April – I managed to fit in 6 hours to try and do some more on this problem. But around two hours after getting nowhere I thought I best reboot.

AT THIS POINT THE PROBLEM RETURNED – BSOD with exact same errors as before.

And when I tried Safe Mode – it would only Boot to similar like CMD prompt.

I used to get by with MS-DOS but I was stumped with what to do now, as DOS was such a long time ago.

So I thought I’ll give option ‘Last Known Good’ a try (it had stopped working last time) but thankfully it worked.

To cut to the chase, after going through what you told me, I found that I didn't follow one section to the letter. My excuse is that I was so tired, BUT STILL SUCH A STUPID & SERIOUS MISTAKE TO MAKE.


You said to do this . . .


2. If that doesn't work - then you will need to make some registry edits manually:

Boot up using last known good.

Then open regedit and use the find function on controlset001 to remove the extra filter,
and also set the start type to 4.

You will need to check the other controlsets (except 005 which is fine because it works)

You can then unistall avast using their tool.


What I’ve gone and done is this . . .


I stupidly deleted controlset001


As a long shot - I was thinking it might be in Recycle Bin, but no.

So I’d be grateful if you could walk me through using RegBak to reinstall the Registry.

That is the file I sent you: system.zip

If it was anything else, I’d give it a go – but the registry is a different matter, after this almighty cock up I've made, I'm not sure I trust myself at the moment.

If I can get the Registry back to how it was – I can then start again and . . .


. . . Then open regedit and use the find function on controlset001 to remove the extra filter,
and also set the start type to 4.


What a numpty I am!

Just so you know, I deleted the new version of AVAST just now, after I installed it straight after I thought I had followed your advise to the letter.

So I’ll be taking a chance all the time I am online. But needs must.

I think I've covered everything.

Many thanks in advance.

Deleted Avast? I hope you mean uninstalled. Probably you are better not using Avast. Use the free Microsoft Security Essentials instead.

I can extract controlset001 from your zipped upload as a .reg file. You should be able to merge it just by clicking on it.

I have removed the filter and set start to 4 on aswardisk service.

ControlSet001-tempfix.zip



If you are stuck and can't boot in, then you can restore from regbak. You need to use boot media and from there you run the RegRes.cmd

This Boot media contains windows explorer, so you can see what you are doing:

64 bit:
17514x86.iso

32 bit:
17514x64-v10.iso

If you need /want to reinstall windows 7, it is actually quite quick and easy nowadays. Getting the updates is much easier using a tool called dism++.

It takes about 15 mins to install win 7, then about an hour for dism++ to get the updates and install them.

All easy enough so far. I have lost count of the number of times I have done it.

The tricky bit is then you have to reinstall your programs - you might not have the program installers and ( if you are using paid 3rd party software) any license keys.

You could create another partition on your hard drive ( if you have space).

Then clean reinstall onto that. Your original installation therefore remains intact. You will have an additional entry on the boot menu - so you just select to boot into your original, or your new installation Then when you have completed updates, setting up, reinstalling your programs to your satisfaction - you just switch to using the new installation all the time.
