Computer hangs when loading Windows 7

Recommended Posts

Whenever I try to boot into Windows 7, the computer hangs at the Windows flag loading screen. If I try to boot into Safe Mode, Safe Mode with Command Prompt, or Safe Mode with Networking, the list of loaded drivers hangs at C:\Windows\System32\DRIVERS\CLASSPNP.SYS. Also, I can’t boot into a System Recovery Disk or System Recovery however, I can boot into Kaspersky Rescue Disk. Is there a way to resolve this matter?

Hello Winlogon.

Is Windows 7 natively installed on the hardware? or possibly, do you have it running in a VM?

Do you have a mirror-image backup of this system? done before this

Do you have the Windows 7 DVD from when you bought the machine?

Did you ever make a "rescue" DVD or usb-flash ?

Do you have another pc that is running Windows 7 with the very same bit-tedness (32-bit / 64-bit) ?

How long did you wait when attempting to get into Safe mode With Networking / Safe mode?

Try again and have plenty of patience. Infinite patience

I would give it at least 20 / 25 minutes to show either a login prompt / desktop, or some "error message".

IF you have attached external storage devices, or CD / DVD, or printer, scanner, etc .....then disconnect them for the time being.

Tell me what significant change or happenstance occurred just before "problem".

It is installed on the hard drive and it is not a VM. The longest I have waited for it to try to boot is one hour. It did nothing from then. There have been some issues with the hardware, I’ve had to restore it to factory settings many times (as I don’t have a Windows 7 disk) and I was not able to install anti-virus due to an unknown reason. Another thing I’ve picked up, whenever I’ve run memtest or Windows Memory Diagnostic, it noticed a problem with the hard drive, but I dismissed the results as the computer was working fine then. I’ve got a laptop with Windows 7 Home Premium like my standalone which has Classpnp.sys on it. Will I be able to make a copy of it to a memory stick and copy it with Kaspersky Rescue Disk? By the way, I’m not sure what the bit is of the standalone - all I know is that my laptop is 64 bit.

@ Winlogon

After you have got & run the HDD diagnostic, let us know what is the result.

If there is still an issue, getting into normal mode Windows, then ....

What brand is the pc?

How old is it?

Was Windows 7 pre-loaded on it when you bought it?

One presumes that you did a factory restore, you did it by following the manufacturer's instructions for doing so from the hidden partition.

For sanity's sake, be very sure the system is not having over-heating issues.

Make sure the vents are clear in back of the case, and free of dust and foreign objects.

The fact that this system did not have an installed antivirus is of high-concern, as it is more than likely a real virus would have corrupted the Windows 7 o.s.

Is this system with the problem here -- a standalone tower or typical Desktop? or if not, what?

Try to not confuse me as to whether this one is the laptop, or if the laptop is the good one?

TRY carefully, deliberatly, and with lots of patience to get to a Command prompt.

Then we can try some things.

Disconnect any external storage drives from the computer.

Enter System Recovery Options.

To enter System Recovery Options from the Advanced Boot Options:

  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  • Use the arrow keys to select the Repair your computer menu item.
  • Select English as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account an click Next.

OR If you have the Windows o.s. DVD, then To enter System Recovery Options, by using Windows installation disc:

  • Insert the installation disc.
  • Restart your computer.
  • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  • Click Repair your computer.
  • Select English as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.

On the System Recovery Options menu you will get the following options:

    • Startup Repair
    • System Restore
    • Windows Complete PC Restore
    • Windows Memory Diagnostic Tool
    • Command Prompt i_arrow-l.gif

[*]Select Command Prompt

Once after you are in the Command prompt, let me know.

I can’t download anything as my Wi-Fi is extremely slow, also I can’t access System Recovery – the screen just goes blue. My laptop is the good one and my standalone (hard drive and monitor) is the one that won’t boot. The standalone is a Compaq and Windows 7 Home Premium was pre-installed on the system. The standalone is about 3 years.

If you have two computers, use the GOOD computer to download an ISO image from the hard disk manufacturer and burn a CDROM using that computer. These ISO images are not large and two days have already passed. You could have downloaded them even with a Dial-Up Networking (DUN) connection.

FYI ...

a good little burner program (if you don't have one) is "infrarecorder" ... simple and easy to use .

(make sure that you select burning the iso at a slow speed)

get it here : www.http://sourceforge.net/projects/infrarecorder/files/latest/download?source=directory
