    repeated BSOD instances, iAstor.sys in error msg


    Hi,

    I've been recently experiencing some BSOD on my laptop that I've had for 3 months. The error messages tend to be different so I really can't figure out what is causing the issue (that and when it happens, the restart occurs quickly so I can't see the exact message sometimes) but I did see that it mentions iAstor.sys on the reason occasionally.

    I've already reformatted the laptop twice (which solved the issue somewhat for a couple of weeks), but I've recently been experiencing them again and I'm now at a loss on what to do next. I've attached the logs as per the forum guidelines as well.

    Any help would be much appreciated.

    There is no dump file included. Please upload it.
    iAstor.sys is a Intel Storage driver. please update these drivers.
