Is there a CLASSPNP.sys boot error fix yet?
I've read through all the information I can find on technet about this problem but have yet to find a concrete solution. Basicaly the system wont move past the windows animation at startup and when put in safe mode it hangs when trying to load classpnp.sys I've tried: Upgrading the BIOS copying an older classpnp.sys through a ubuntu live cd. It just tells me that it cannot mount the drives because they are in use due to a bad shutdown. Windows 7 Repair disks: these simply hang and present me with a black screen after getting past the small load bar. Any ideas?

It should be a hardware compatibility issue. You may boot in WinRE and run System Restore to restore the system to a previous version. Then I suggest you download the latest chipset drivers for your motherboard and install them. Please note that they need to be indicated as compatible with Windows 7.Arthur Xie - MSFT
