I am trying to load Windows 7 Home 64-bit on an HP HDX9200 Notebook PC but after loading the installation files, the install hangs at the "Starting Windows" screen. This machine once had Windows Vista Ultimate 64-bit and I've tried the System Recovery DVD (1 of 2) with the same result. I've even tried replacing the HDD with one that already has Windows 7 loaded with no success.
After Booting into Safe Mode with Command Prompt and Safe Mode disabling driver signature enforcement it says: Loaded: \Windows\system32\drivers\ CLASSPNP.SYS. My research says that a piece of hardware is causing the problem hence the reason I am posting in this forum. Since the Hard drive and Memory tests passed, I've removed 1) SPS 441086-001 Wifi WIRELESS N CARD and 2) AVerMedia TV Tuner Mini-pci-e Board Card but still get the CLASSPNP.SYS. Could it be a problem with the graphics card, or CPU?? I've been trying to repair my computer for a month and at my wits end. Any help would be greatly appreciated.
