  1. Hi

    I have been experiencing BSOD more and more frequently recently. I have finally decide to ask for help after being unable to fix the issue alone.

    I have an Acer Aspire 4736ZG laptop running Windows 7x64

    I have attached two minidump files.

    The most recent message I got was driver irql not less or equal and jmcr.sys

    The message is not always the same though, occasionally I get a paged in a nonpaged fault (something like that anyway...)

    If you need any more info please let me know.

    Thank you :)

    Blue screen of death could be caused by many reasons. This could be due to a virus infection or incompatible drivers.Also it could be hardware faults, for example, dust inside your laptop.
    Good Luck :)

    Ok thanks for that. So what I have done so far is basically all of the suggestions outline in this article

    I can't post links cos Im new here... but the details are:

    I have also done the following from that link you sent:
    Last Known Good Configuration - done it.
    System Restore - done it.

    Haven't tried the virus scan in safe mode - I will try that.

    Fingers crossed!

    Thanks for that link - I hope I don't have to do those things!

    I realised that I had only about 10% of each drive free, which I thought was acceptable, but perhaps it wasn't. I was ruthless and cleared out a ton of stuff that I probably won't miss and managed to free up several 10's of GB.

    Since doing that I have not had a repeat performance. But I haven't been doing anything too intensive so only time will tell!

    I hope this has fixed it - simplest solutions are the best ay?
