BSOD after running CCleaner

I'm trying to clean up someone's computer which is so slow to do anything on it...takes forever to start up.

I ran SuperAntiSpyware and Malwarebytes which removed bunch of adware and other viruses...seemed to have sped it up a little.

I then ran the Ccleaner which he had on his computer which cleaned up files, then ran the Ccleaner registry and when I rebooted, I got the BSOD.

I ran a chkdsk and it didn't find anything.

I tried to do a Startup Repair, but it says it could not repair the system, but in the report, it says my registry is corrupted.

Tried to run a system restore, but it says it could not complete the operation.

Tried to run a sfc /scannow, but it says there's a system repair pending and to reboot and run the sfc again.

Tried to run in safe mode, but keep getting the BSOD.

I'm uncertain about how to use the dm log collector when I can't get past the BSOD.

Is there a way to access command prompt without going through repair menu?

Specs:
Dell XPS Tower with Intel core 2 quad, 4gb memory, 500gb hd running windows 7.

Nobody has any suggestions?

Yes, when it comes to this sort of thing where malware and Adware crap is abound, I'm afraid a format and reinstall of Windows is more suitable.

Backup the data, scan that data in a live system and reinstall Windows.

That BSOD is more than likely due to something (malware/Adware?) messing around with drivers. 99% of all BSODs are driver or hardware related. Install a bad driver and get a BSOD. Something messes with a driver and get a BSOD. Install bad hardware and get a BSOD. You get the point. The Whocrashed program can help...

Oh, Ccleaner registry cleaner is snake oil and will F%^7 your computer up. you DO NOT need to EVER "clean up" a registry. No one should EVER mess with the registry, Now you see what happened. Ccleaner is also a real "crap" program. Just use SystemNinja once every few months and call it a day.

You might be able to run the Windows 7 recovery environment and invoke a system restore point therefore writing the registry back. Hopefully...

How to start the Windows 7 Recovery Environment

y,

I would re-install Windows 7.

I did run into this problem when was using CCleaner, which is free. That means couldn't get any help.

I had to go re-install, an easy and quick solution. then backup the fresh clean OS. anytime when needed, I just restored its image.

Thanks for replying....Unfortunately, I did not back up anything.

"Back up the data...Scan the data in a live system."
How do I do this? Is there a way to back up from the command prompt?

I've tried Last known good config., safe mode, system restore nothing seems to work.

Whatever repair I try, it attempts to fix it, but never completes successfully, and always results going back to BSOD.

I also should mention, when I used the Ccleaner, I also disabled some 4 startup programs that said Seagate something. The tower has a Hitachi hd, and since it was so slow to start I disabled it. Could this have something to do with it?

Is this fixable without reinstall...Should I take it to a repair shop?

Any this kind of solution will be tedious.

here is a relatively easy way.
1. stop any work on the existing disk. stop any further damage/change on it.
2. get a spare disk, clean install Windows 7 on it. then attach the existing disk (above one in item#1) to the new Windows 7 OS.
3. now copy/move files needed to a safe place. on new Windows 7 OS, you should be able to do this (Dell desktop tower will be easy)
4. next depends on your PC organization. either move all files to new disk. or clean re-install the 1st/old disk, then put the files back (since you have all files in a safe place. i.e. a backup).

I tried this yesterday and it didn't seem to work.
Put a clean install on another hd, and attached it to the tower.
Put the BSOD hd on the second plug on the cable attachments, since it would not boot up in the first plug.
After hooking up both hds, I plugged the tower back in and started it again, but the new clean install doesn't recognize the BSOD hd.
Should I have attached the BSOD hd, after I boot up from the new installation while the system is running...is it safe to do this?

Don't do hot-switch (plug-n-play). On old system, I am uncomfortable to do that.

As said, it's tedious. hence, slowly step-by-step do it.

when fresh install of Windows 7 done, play it awhile. make sure no issue.

then power it down.

then add "the old disk" into system.

now re-start PC again, remember to boot from the newly-installed Windows 7 OS (which you have proved no issue when install done). Don't boot from the old disk.

read files on the old disk under newly-installed Windows 7 OS. if you cannot do this step. my understand is, the old disk has been damaged. at least its file table ruined. very low chance. but could be.

Disk damage repair will need disk tool. that will be another task, usually expensive.

Did everything as you said, but the new install just doesn't recognize the BSOD hd.
Oh, maybe I should update the new install of Windows update...see if that'll help.

Hi

general overview fix,
The error means CC has corrupted the registry
Now the only way your going to get it back is to REVERSE what CC did

Not done it myself but you are gong to have to get into Recovery command mode
search for the CC reg cleaner log --- there should be a Reveral option... run it
