"Unexpected Kernel Mode Trap (Wdf01000.sys)" and a Blue Screen appearing frequently on my Windows 8.1 (64-bit) laptop and laptop restarting all of a sudden. RRS feed

  • Question

  • Hi I am Arka Dey. I am using a Windows 8.1 64-bit single language Dell laptop. Recently I have installed an update to my Windows 8.1 (X-64) operating system from the "Windows Update" available in the "Control Panel" section of my laptop. But from that very day when I installed the updates, my laptop started behaving weird sometimes.

    The problem is while I am using my laptop, a blue screen suddenly appears and it says, " Your PC has run into a problem and needs to be restarted." Along with it there is written the following message: " You can later search for this online - Unexpected Kernel Mode Trap (Wdf01000.sys)". After displaying this for a few seconds in the blue screen mode, my laptop automatically restarts. This has been happening for sometime for the past few weeks. I do not understand the meaning of the message displayed in the blue screen and nor do I know the reason behind its occurrence. Please help me with a solution to this irritating problem as I am not a student of computer related sciences and software technologies. Neither am I that tech savvy. So please do help me with a guide or set of instructions to solve this problem of mine. The detailed specifications of my laptop are given as follows:-
