    Hello all,
    I just installed downloade Windows 7 Ulitmate x64 from technet plus and installed on a new PC with follwoing config:

    Motherboard: ECS X58B-A
    CPU:  Intel Core i7 920 Nehalem 2.66GHZ
    Memory - Corsair XMS3 6GB (3X2GB) total RAM 12GB
    Graphic: Gigabyte GV-R4677ZL rADEON hd 4670
    HDD:  Seagate Barracuda 7200.12 1TB 7200 RPM SATA 3.0Gb/s (2 OF THE SAME in a RAID1 configuration)

    Windows 7 installs without any issues and I am able to login and update all the Windows 7 drivers.  However, the system is choppy, and freezes.  The only way to unfreeze it is to do a reset.  When the system reboots, it takes about 10-15 minutes sitting on the Windows 7 icon saying "starting Windows".  When running it in Safe Mode, it gets stuck at ClassPNP.SYS for about 10-15 minutes and finally reboots.

    I am thinking about going back to XP - Vista may have the same issue.  Any ideas???

    Thanks in advance,

    Walid

    Hi,

     I've the same problem BUT only when I add a framegrabber to my system configuration. If I remove the framegrabber Windows 7 boots again without any problems

     my config:
     
    MB: DFI LANPARTY DK X58-T3eH6
    CPU: Intel Core i7 920
    Mem: 6GB (3x2)
    Graphic: NVIDIA Quadro FX1800 & FX580
    HDD: Hitachi 320 GB

    regards,

    I updated flashed the bios with the latest firmware and the problem went away.  So far, no issues since then - Windows 7 Ultimate 64-bit runs great on my machine.  Very nice!

    Try this... Its working for me at the moment after days of screaming with the same issues your having

    When you go into your BIOS -> F12 (for my gateway) -> select Run from CD/DVD on your Windows 7 disk for fresh install (i think ya'll are not having any issues at this point) -> let it install.  WHEN IT DOES ITS FIRST REBOOT Go into BIOS again, then select run from HDD.

    For some reason, what i think the reason is that its trying to run from the Win7 disk again and from the HDD causing somekind of loop at classpnp.sys

    I hope that helps.... let me know how that goes.

    Hi,

    follow my guide here to make a boot trace:
    http://www.msfn.org/board/index.php?showtopic=140247

    and compress the boot_BASE+CSWITCH+DRIVERS+POWER_1.etl as 7z or RAR and upload it to your Skydrive and post the link here. I take a look at the trace, maybe I see what's wrong with your Windows.

    regards
