    I'm using a Lenovo Z51-70 Type 80k6.

    My touchpad stopped working properly a couple of days ago. I had a couple of blue screens too. Every time restarting fixed the problem.

    Until two days ago It happened again. I did a restart and It fixed the problem, but my USB mouse stopped working.
    I used it on another device to make sure it's not the issue and did a quick search to find out what's my options. I tried everything I found online and nothing worked. In the end I uninstalled pointing device drivers and restarted again. This time windows gave me an "Inaccessible Boot Device" Error and didn't let me get into it. I found out my USB ports have stopped working too.
    I spent one day using every possible method but a clean install and, chkdsk didn't report any problems, troubleshooting options didn't work, even the reset failed. Since I couldn't format C to do a clean install, I installed an older version of win10 on another drive.

    Now I could sign in my new user account, but again USB ports not working --- drivers didn't indicate any problems.
    After a couple of restarts my touchpad stopped working -code 10 in device manager: "This device cannot start"- and I couldn't get it to work by reinstalling drivers and changing power options.

    I can't risk losing any of my files, so I'm avoiding any kind of HD format.
    Any help would be appreciated. Thanks.

    PS: If I remember correctly Windows installed two major updates right before the second restart.
