Frequent BSODs on Windows 7

  1. I recently bought a Toshiba Satellite and it has been working great until a few weeks ago when I started getting BSODs frequently. I looked at some of the forums for general answers but I believe the problem may have to do more with incorrect drivers or software rather than a memory issue since it is a new computer and for the most part shouldn't be having problems this early in its life.

    Upon restart windows gives me the following information, these are a few of them that I have gotten today:

    Problem signature:
    Problem Event Name: BlueScreen
    OS Version: 6.1.7600.2.0.0.768.3
    Locale ID: 1033

    Additional information about the problem:
    BCCode: 7f
    BCP1: 0000000000000008
    BCP2: 0000000080050033
    BCP3: 00000000000006F8
    BCP4: FFFFF8000344AEC8
    OS Version: 6_1_7600
    Service Pack: 0_0
    Product: 768_1

    Files that help describe the problem:
    C:\Windows\Minidump\082110-19656-01.dmp
    C:\Users\Tyler\AppData\Local\Temp\WER-39437-0.sysdata.xml

    This is mostly Greek to me and am not sure where to start in the troubleshooting process. I appreciate any help on the subject.

    Kindly attach minidumps for analysis with your next post, you can find them in C:\windows\minidump. What is the model number of this Toshiba Satelite notebook or either you can simply give us its complete specs. Regards

    Out of these five dumps, four crashes occurred due to 0x7F error (with 0x08 as first argument) i.e. double fault.

    A double fault occurs when an exception occurs while trying to call the handler for a prior exception. Normally, the two exceptions can be handled serially, however there are several exceptions that cannot be handled serially and in this situation the processor signals a double fault. The two primary causes for this are hardware and kernel stack overflows. Hardware problems are usually related to CPU, RAM, or bus. Kernel stack overflows are almost always caused by faulty kernel-mode drivers.

    Please follow these following steps to troubleshoot which hardware component may be causing it:

    1. Test your RAM with memtest, it would be prudent if you test each module individually, run memtest for minimum of 8 steps. Also note that Mismatched memory modules can cause this issue.

    2. If you are over clocking the speed of your processor, set it back to the speed at which it is designed to run.

    3. Motherboard issues can also cause this situation (but for now lets ignore it, till we rule out all other avenues).

    The other remaining system crash was with error 0x51 citing Registry Error, which occurs when registry got an I/O error while trying to read one of its files, so it can be caused by hardware problems or filesystem corruption. Therefore, download diagnostic tool from your hard disk manufacturer's site, and thoroughly test your hard disk.

    Please keep us updated about your progress. Regards

    I tested my ram for about ten runs and there weren't any errors that it detected. I believe the problem is resolved though - it ended up being a conflict with Windows 7 and ZoneAlarm. Apparently the free version of ZA blocks IPv6 (or something, I'm not terribly computer savvy) and it was causing the blue screens. So i uninstalled it and so far I haven't had any problems.

    Thank you again so much for your help, I really appreciate it.

    Ah ZoneAlarm again ......... it hasn't been any good since Vista was released, thanks for the update. I would suggest you to try Commodo Personal Firewall or Online Armor. Both of these are pretty good options, however, Commodo needs more steep learning curve.
