    BSOD BC Code d1

    First time poster and useless pc knowledge, so please go easy with me.

    Tun on the PC - OK
    Login - OK
    Using the mouse - No Problems
    Type on the keyboard - PC Freezes, Blue Screen appears with the following:

    OS Version: 6.0.6002.2.2.0.768.3
    LocaleID: 2057

    BC Code: d1
    BCP1: 871FC434
    BCP2: 00000002
    BCP3: 00000008
    BCP4: 871FC434
    Service Pack 2
    Product 768_1

    No idea where to go now after many hours hunting the internet.
    Can anyone help please?

    Code D1 relates to device drivers.

    The fact that you are using the keyboard would point me in that direction, however to be safe post a mini dump.

    Welcome
    Its really good that you took the time to post. The culprit, as Roy said, is a driver:
    KbdF.sys.
    There is a possiblity that this is a keylogger..

    Hi Rich,

    Thanks for taking the time to reply.

    No I haven't (knowingly) installed any keylogger hardware or software.

    My PC was repaired recently (new motherboard!!) but worked well for a couple of week or so. The problem arose a little while ago. I carried out a system recovery/restore but to no avail. I've also noticed that the problem seems to be intermittent. Somedays it works fine, others it has a fit?!?!? Weird.

    Not trying to scare but to warn so you can take action. If you did nothing someone could be logging your key strokes. Make a full anti virus scan, download and make a full scan with Malarebytes.

    Thanks again Rich,

    I couldn't find 'Malarebytes' soI downloaded Malwarebytes instead (only joking).
    Quick scan didn't find anything. Restarted the PC just in case and low and behold same problem?!?!?!?

    I'm leaving the country for a couple of weeks to recharge my batteries , so i'll have another look when I return.

    Any other advice would be most appreciated.

    The above relates my true concerns about your problem. I have Googled and found that many that use Kaspensky Anti Virus have reported that this malware was found. Use this link to tak an online scan. Its the last button. If negative, we will work on just solving the problem.
    Free Virus Scan - Kaspersky Lab
    Dont let the site fool you into buying or paying for anything, do the free scan.

    Hi Rich,

    Back from holiday and nothing changed.

    I've completed the Kapersky scans as suggested with no luck. In fact they came back with a free error report.

    I've even bought a new keyboard (just in case!!), but still having the same problems.

    Any further suggetions would obviuosly be most welcome.

    Thanks again.
