Extremely Slow Windows 7 Startup but Runs Fine RRS feed

  • Question

  • I saw many other posts about this, but none seemed to fit.

    Starting early last Friday, my Windows 7 Home (64-bit) startup is EXTREMELY slow.  I’m talking an hour or two.  Once finally started, all seems fine.  All Safe Modes arealso horribly slow, except for Safe Mode with Command Prompt.

    My wife had a more recent Windows Update than me (June 26), so I suspect that update may have failed. 

    I do not have an install CD to try a Windows Repair as I bought and downloaded the Windows 7 Upgrade from the Microsoft web site.

    Another possibility could be driver updates via PC Matic.

    However, again, system seems to run fine, once I get it going.

    I’ve already tried several things:

      • Ran PC Matic to clean up my system
      • Ran a full virus scan with both PC Matic and MalwareBytes.  The following were flagged and cleaned.
      • Trojan. Win32. Sirefef. ag (v)Trojan.Win32.Generic!BT
    • MalwareBytes was installed just for this triage, then uninstalled
    • Only one antivirus program is running (PC Matic)
      • Clean Boot via msconfig.
        • Didn’t seem to help at all.
      • Windows Startup Repair
        • No help
      • Sfc /scannow
        • Gets to 18%, stalls, then fails
        • Windows Resource Protection could not perform the requested operation.
      • Restore point
        • Only had one, which seemed odd
      • Uninstalling multiple Windows Updates.
        • Each uninstall seemed to help a LITTLE.
        • I think this finally got me started to the point where I could run.
        • One odd situation:  System started normally after re-installing one Windows Update, but an immediate restart was slow again.
      • Checked devices for warnings on drivers
        • All looked fine.
      • Checked c:\windows\ntbtlog.txt
        • Noticed a couple of drivers failed to load.

    Did not load driver \SystemRoot\System32\drivers\vga.sys

    Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS

    Did not load driver \SystemRoot\System32\DRIVERS\srv.sys

    I have seen a couple of notifications about Windows not being “genuine”.  Seemed odd too, but easily fixed, by clicking to the Microsoft site.

  • 1) Please, download ProcMon or Process Explorer , open and analyze all processes at startup.
    2) Boot into last known good configuration (press F8 during system boot)

    3) Scan your system disk 

    chkdsk C: /r

    3) Perform full defragmentation , including system boot files

    defrag C: /v /w /b

    4) Not recommended: In-Place Upgrade
