Windows reboots after classpnp.sys

It just stops dead in its tracks until you hit the reset button. But I fully agree with you that in this day and age of smart OSs, it is inexcusable for any OS to be as obtuse as this.

It should be simple to add a subsystem to keep track of what the system wanted to do, whether it in fact did it, and if not, what prevented it.

Like it is supposed to do with standby issues. I do think your issue and mine are probably related, though. Modifications of the settings are at your own risk.

Hi, Thank you for posting in Technet. Put this disk in your computer and boot from it.

Follow the instructions. Once completed and if works you may find some of your docs photos etc missing. If you can find away of backing these before doing this I recommend doing so. Solution 3: This requires more downloading and the software Imgburn that I talked about above.

Once downloaded the process is similar to the one above. Shut down your PC and start it up again. Once that is completed insert the disk into the computer and boot using the Ubuntu software.

This acts like a Operating system. Replace the old one that you have renamed with the newly downloaded one. Exit and restart your system making sure you are going back into Windows 7 not Ubuntu. The system will lag for a bit but should eventually go into Windows 7 safe mode assuming you ticked the Safe mode box in msconfig.

Solution 4: Wait for your computer restart again or turn it back on. When your computer loads to manufacturers screen one of the first screens you will see when starting you computer.

Provided you still have Acer eRecovery installed, or your brand of recovery system it should come up. From this point the software should update the C drive with a fully functional image from a secret partition on the hard drive.

It is very important to note that this Secret Partition is very secret indeed, you can not see it or touch in almost any other way except for dong this. This process should take around ten minutes if working correctly. When the software has finished running press OK and reboot your computer with fingers crossed and any other limbs and appendages you have.

Solution 5. Wait for your computer start. Tap F8 to bring up the menu. Click system restore, this is the very first option. Wait for this to load. If its your first time, be gentle it may take a little while. Once it has loaded click on the Command Prompt and type in "Restore" with out the quotation marks of course. Press Y and go with the flow. And lastly the worst option I can think of. Solution 6: Reformat and reinstall your choice of windows; XP, Vista, Windows 7 or you could even go 98 if your system is compatible.

I don't really want to do this but I may have to yet. I will be going back to vista as I will wait for Windows 8. Luckily I also have all my video and music content saved on hard drive. The only thing I am going to loose are my save game files but I that is no where near the end of the world now is it.

There is also the last, well can't really call this a solution lets call it an option. Option 7: Find the nearest high rise building, the tallest building in your area should do. Climb to the top using any means necessary ladder, stairs, elevator etc. My bad Proposed as answer by Fernan Wednesday, March 10, AM.

Ok so I have fixed the problem. For some of you who have read this thread your not going to like the answers. Solutions 2 and 4 worked. Option 7 would have achieved all it set out to do seeing as i managed to fix my computer I didn't not try. For those you who have not backed up there computers you will loose all data that was not backed up.

I am not going to re-upgrade to Windows 7 as it was pointless. I found no benefit other than it looked a little cooler than its counterpart of Vista. Also with Windows 8 on the horizon I don't see the point.

I still havent solved how I am going to get fallout 3 working with crashing in safe mode again. I have yet to understand the reason that why classpnp. Also the reason on my computer under the vista operating system is still unclear.

Hello, The problem should be caused by the corrupted system files. Click Start and choose Computer. Please find the "setup. Click Install now. When we are prompted to input the product key, please click Next without inputting any key. The setup wizard will prompt and ask if you agree to install Windows 7 without the key.

Please choose to confirm. When you reach the "Which type of installation do you want" screen, click Upgrade to upgrade the system files of Windows 7. As it happens when you buy the computer you do not receive a Windows 7 disc, or as I brought my computer just a week before the official release I got Vista. As you may see from my above post, I fixed the issue.

In the past few hours also got fallout 3 installed with out going into safe mode. However thankyou for your input. Thursday, March 11, AM.
