Computer not booting, startup repair won't work

What registry cleaner did you use? Did you use the backup that most registry have?
This may or may not help, sfc /scannow from cmd prompt/admin. If it finds a problem run it 3 more times rebooting between each one. Sfc= system file checker. IMHO if that doesn't work a repair and install would be next.
A little note: Letting us know in you first post you used this registry cleaner would of helped.

Maybe I should just use the recovery partition on the system? But I don't want to get rid of all my stuff. Maybe I should just wait?

You can use Repair Install


Normally you will not get rid anything.


Dont use registry cleaners,in the most of the cases rc make things worst.

Old drivers needs to update

Code:

AtiPcie.sys        0x8c068000    0x8c070000    0x00008000    0x4a005480    05-May-09 6:00:16 μμ

But I also might know the culprit, because before I installed some registry cleaner it was working fine... I'm not entirely sure though. Any news from the BSOD analyst?

Ouch....most people should steer clear of these registry cleaners. Did you miss my post where I cautioned against installing MSE without unintsalling Norton?

The BSOD fella's are in high demand so you might need to be a bit more patient until one of them is free - I have asked them to look at this when they get a chance.

For now, I recommend justing waiting until they've had a chance to look at your jcgriff file.

While waiting for the the people to get free you could run sfc /scannow. It can't hurt and my help.

Hi there,

The dump reveals bugcheck 0x6B, "Process Initialization Failed". I see this error:

Code:

First thing, uninstall IoBit Advanced System Care. That alone may solve the problem.

I see one other thing that catches my eye:

You might try using Revo Uninstaller in Advanced mode to remove Advanced System Care. After the uninstaller fails, Revo will manually delete everything it can find.

I won't discourage you from using the recovery partition. That probably is the best way to do it, but if you don't want to lose your files and all you can try other things first. If you want to just backup your files and then use the recovery partition, you can do that as well. If you need help with any data backup, we can help advise you.
