Windows 7 Pro hangs at classpnp.sys

Jan 8, 2015 10:10AM PST

I installed a new SSD into my desktop, installed Windows 7 Pro on it, and applied all the available updates to it (restarting several times in the process). Now my computer takes forever to boot. It used to start at the very end of the "Starting Windows" animation, but now it doesn't load until about 10 minutes later. When it finishes loading, it's as fast as it was before it started doing this.

I know that this issue is not caused by failing hardware as I installed Ubuntu 14.04 on it after having this problem and it booted in (Literally) 5 seconds.

Following others suggestions on various websites I have tried reinstalling windows (I think I'm on my 3rd installation), running system restore, running the windows recovery tool, running checkdisk, running tests on my RAM, booting in safe mode, removing any unnecessary hard drives and USB drives, and running fc /SCANNOW /OFFBOOTDIR=C:\ /OFFWINDIR=C:\Windows in the command prompt in windows recovery.

System specs:

- Intel i7 3770k
- 16GB RAM
- Samsung 850 EVO SSD (250 GB)
- Segate Baracuda 1TB 7,500 RPM
- Nvidia GTX 650 TI SSC

It didn't work
Jan 8, 2015 12:48PM PST

sadly renaming the file after fighting with the windows command line (I'm a bit of a Linux fan, so using comnands like "dir" is very couterintuitive) it didn't seem to do anything, but it also didn't blue screen like the person in the form said.

In linux we use ls
Jan 8, 2015 1:56PM PST

Since ls and dir are basic skill items, if you know Linux and use ls, cd, there's not much to learn from one OS to the next.

Windows repair is too varied for me to give any exact answer. Maybe if we knew what lead up to this blowup?

I do have one idea. If one uses hibernation and changes ram sizes, it can blow/hang.

sorry about setting the post to "urgent"

Sorry about setting the post to "urgent" I didn't know that there where other people in much worse situations then what I'm in and I don't know how to change it to something less dramatic.
