LOL - that sounds forlorn.

Ther are a couple of things to try now.

One is to replace the driver - classpnp.sys with another.

Attachment 153487

Obviously, you need to take it out of the .zip file first.

The other is to run checkdisk.

Seems you can't to do the second option atm.

Try replacing the driver - you need to copy it into windows\system32\drivers.

You will need something that can boot to do that.

Suggest you try a Linux boot disc - parted magic will probably do the job.

http://partedmagic.com/doku.php?id=downloads

download the .iso and burn as an image to cd.

You will nedd acces to another to do that.

Then boot the cd you made on the sick machine.

You will need to be able to get to the replacement classpnp.sys from there - put it on a acd or flash - then copy it into windows\system32\drivers.

You can't run checkdisk - so your other option if the above doesn't work - is take it back to the shop as it is only amonth old.

Hi, found this while googling, I rebooted pc after removing nod 32, went into safe mode and pc locked on after loading ati driver? locked solid. Tried to boot into windows normally locked solid on windows logo. Booted from rescue disk locked solid on the loading bar!
All fans were running, I thought psu had gone, before kicking it out the window I reset cmos and everything was fine.
I have since restored from an image, have no idea what caused this, but I didnt check any hardware, ie pressing ram in etc, just rest cmos.
try that.
very mystified as to what on earth happened?
hope that helps anyway.

Hi there. This morning I had found that my PC was stuck in shutting down mode. This seems to happen when Microsoft automatically performed an update. I'm shutting that off today. Anyway I tried rebooting and my machine would never reach the Windows splash screen. I tried doing a repair but Windows didn't find anything wrong. I rebooted using the option that allowed me to see the post boot messages. It hung on classpnp.sys. I tried rebooting in safe mode but the same thing happened. I found in a posting somewhere on this site some things to try.

I tried renaming the classpnp.sys to classpnp.old. When I rebooted it rebooted, then rebooted again and automatically launch system repair. After is scanned system startup files it said it couldn't help me. So I went back and renamed classpnp.old back to classpnp.sys.

Ultimately I went into bios and reset everything to default. That seemed to work for me yea!
