Windows 7 slow down and then Blue Screen


  • I recently recieved a new gateway for christmas, but it has started bugging out lately. Sometimes, when i am on it, the mouse and whatever i am doing will have terrible lag. If I look at my computer's CPU usage, even after closing all applications, will hover around 30-40 while my system idle process is right at about 97%. If i try to start any apps, the computer flashes the blue screen then shuts off. I've run many virus scans with avast! but gotten nothing. If it helps, it seems to only happen after i get off youtube.

    My computer specs are:
    Windows 7 Home Premium 64-bit
    Intel GMA X4500 Intergrated
    DVD super multidrive
    Intel Core 2 Quad Processor Q8300
    4GB DDR2

    Please help me! I love my Comp and want it to last!

  • You may want to start with updating / installing Adobe Flash player / Shockwave Player / Java - if that's the only time you see the error

    Flash -

    Shockwave -

    Java -

    To stop the automatic restart without seeing the Blue Screen -

    You can also examine the event logs for errors -

    • Open Event Viewer by clicking the Start button Picture of the Start button , clicking Control Panel , clicking System and Maintenance , clicking Administrative Tools , and then double-clicking Event Viewer . Administrator permission required  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

    Post back the errors please.

  • Also, can you zip up the minidump files in the C:\Windows\Minidump folder and make available (provide link) via Windows Live SkyDrive or similar site?

    The following link has information on using Windows Live SkyDrive:

  • You may also update the BIOS and the hardware drivers to check the issue.


    In addition, I also would like to suggest you test the issue in Safe Mode and Clean Boot to determine if this is a software or a hardware driver conflicting issue.


    If it works fine in both Safe Mode and Clean Boot , it can be caused by the software conflict.


    If it only works in Safe Mode, the possible cause should be the hardware drivers.

  • Some versions of Flash have problems with memory leaks when playing video. This might be your issue. If the memory allocated to the browser slowly increases (in taskmanager) then this is the likely culprit. Though with 4GB it would take a long time to fill the RAM.

    YouTube doesn't use Acrobat or Java, BTW.

    Seeing as it's a new computer my thoughts go towards a hardware fault, or crapware. It presumably had an OEM copy of Win7, but what other garbage was installed on top of that? Is this the problem area? In particular if it had a preinstalled antivirus, was this fully removed before avast was installed?

    As regards hardware, running it for a while from a bootable CD (Knoppix, Ubuntu, BartPE) might give some insight as to whether the hardware is OK or not. If it starts OK but crashes after a while, chances are it's not OK. Problems of this kind are often due to slightly substandard RAM.

  • The error started rearing its ugly head again after a few months. It seems that if i have a lot running, it will start to lock up or lag, and then give me the blue screen. When this happened, i noticed that even after i closed all of my programs, the cpu usage was still around 48% while my system idle process was still about 98. I will provide the mini dump from when it froze last (the dump is a bit old, since every time the comp starts to lag, i just shut down to preserve data).



    thanks for the help.

  • The dump file indicates a bus error - a hardware error - BUSL0_SRC_ERR_M_NOTIMEOUT_ERR.  Could be motherboard or processor that are failing.  You can try to update the BIOS, try a clean boot or device clean boot, or boot into safe mode, to see if you can reproduce the issue.  

    You might also consider uninstalling Symantec / Norton software - seems a bit old - some drivers associated with it are pre-Win7 RTM.  It also appears you have Avast installed?  Installing multiple AV packages at the same time is almost always a recipe for disaster.

    So while the dump indicates a hardware issue, I'm inclined to suggest uninstalling BOTH AV packages, as well as updating the Realtek driver (RTKVHD64).  See how that goes.  

    What is alu920ro.sys a driver for?  Possibly Daemon tools?  (Get rid of DT, as well.)

    Also check for updates to the Intel NIC driver.  And the drivers that came with the NTI software are pre-Win7 RTM as well.  All of these items could be playing into the issues you are having.

  • Also, besides uninstalling Daemon Tools, also make sure the sptd.sys driver, which Daemon Tools installs, is removed - see "How can I remove SPTD driver on 64-bit OS" in the following link:

    BTW, which Gateway computer do you have?

  • I don't have daemon tools installed. I think what you are noticing is Alcohol 120%. Thanks for the tips though- i will completely uninstall any ____-ware that was on my pc, and all of Norton, and see if that helps.

  • Yes - DT or Alcohol 120% - whatever dropped sptd.sys, as auggy pointed out.

  • I believe i figured it out. A friend gave me the tip of rolling back my graphics drive before os nuking (which i was considering) and it would seem that has fixed it. It hasn't happened in a while (since rolling back the driver) but i also haven't been going on vid sites looking at music and video game playthroughs (i am an amateur game programmer, so i like to use youtube to examine other games and learn what people like from them) so if the error occurs again i will let u guys know.

  • by the way, what exactley is the sptd.sys driver about? is it the virtual drive that Alcohol 120% and DT make?

  • It seems to be some anti-DRM driver that lets the product do some "cool" things. It has elements of a rootkit (on 32-bit systems) that are meant to evade detection by DRM software.

    You post this same misleading reply to many different messages. See
