Windows & Won't Boot Up

Microsoft Microsoft windows xp pro full...

Specs: Windows 7, i7 980x
My computer has been running fine until recently. Nothing changed about the system but all of a sudden the computer froze, got the BSOD and now whenever the primary HD (SSD) drive to load the OS it freezes on the windows 7 startup animation. Safe mode doesn't work and repair doesn't work. Safe mode reached "loaded: classpnp.sys" and then hangs there for a while until eventually the sytem restarts. When I try to access the command prompt to replace classpnp.sys, I can't access the C: drive (it as if the partition isn't being reconized anymore) which is strange because it reconized it enough to load windows at least partially. I also tried reconfiguring some bios settings including setting teh drive to be achi instead of IDE which didn't work either (it's back as IDE now.)

After checking connections and replacing the sata cable, my nex step was to take out the primary hard drive and replace it with a spare HD I had. I then installed windows 7 onto the spare HD and plugged the SSD into a docking station as a secondary drive. The SSD Partition was having trouble being reconized in windows 7 when I plugged it into (USB) the system. I then plugged the same docking station and SSD into a laptop with windows XP Pro installed. Viola the SSD partition was reconized and all my files are in tact.

Now that I know my data is safe, I need to figure out the intial problem and why the OS won't fully load when used as a primary drive. Any thoughts?

This is my primary computer for my business so any help would be appreciated.

Thanks!

If you search google for classpnp.sys, you'll get a lot of hits. One answer was to reset the BIOS. Another said that it was after he installed a game. Repeat the search for more info.

BTW, your data isn't safe until you copy it to an external drive.

I've tried googling. No luck so I thought I would post my specific issue and troubleshooting experiences.

Did you try to reset the BIOS as one post suggested?

Yes, I've reset the bios and don't install games as this is a business computer.

I think there is something wrong with the hard drive. When I try to do any sort of scan when the hard drive is connected to the windows xp system as a secondary drive, the drive ends up disconecting and needs to be reconnected to be mounted again. Is there any way to repair a bad sector without it dismounting? I want to try to save the hard drive and also would like to avoid reninstalling the OS.

You can download the manufacturer's diagnostic tools & boot with that. For example, if the drive is western digital, download the tools from their site.

It's a SSD from OCZ. I don't think they have a recovery tool. I tried downloading other recovery tools but it seems like when it reaches a bad sector during the scan, the hard drive freezes. Is there any way around this so that I can recover data that isn't on a bad sector?

If you can boot to a command prompt, you can copy the data to a USB drive.

If that doesn't work, you can use a hard drive USB enclosure to connect it to another PC & recover the data. I bought a nice one from Radio Shack.

try running "Recuva" while its acting as a second drive in the xp machine, although if it is damaged you may not be able to recover everything, recuva is free and very good at recovering, lost deleted data and partitions, give it a try.
