Solved keyboard, touchpad not working after autorun

[saturnavinav]

Hi, after i unchecked a few yellow highlighted drivers and windows mail, outlook unsigned addins, i have been unable to use my keyboard & touchpad. Keys are not doing anything. I checked again red highlighted lines in autorun except addins and mail. I also don't see any information under keyboard in system summary & no device for it in device manager. One problem that is showing in device manager is intel ICH9M LPC interface controller 2919 states that a driver for this device is disabled. please help.

additionally, i found that keyboard works before booting start. then display is lost, then using sleep and resuming windows i login, using on-screen keyboard.

Problem solved: I logged in as administrator to avoid repetetive password prompt. Then uninstalled display driver. I disabled/uninstalled some of the conflicting resource users under system summary under system information. I also uninstalled Intel ICH9M LPC interface controller 2919. In administrator account, now i get the message to restart in order to apply changes every time i login, which i think i shall solve by power-drain sometime later.

For anyone looking for a solution to this who doesn't have a restore point, I've have one for you.


Some background: I was trying to remove a virus with autoruns, I also took the opportunity to untick some things I didn't recognize. I've now realised that is not the purpose of this tool, and disabling software at boot should be done by other means.


My Fix: I couldn't get into safe mode by pressing F8 I guess due to my keyboard not loading. Luckily, if you keep hard reseting windows during login, it tries to troubleshoot. From that menu you want to go into the command prompt screen. I got a few errors trying to do this, and had to keep rebooting and eventually I got a prompt. Once you're in the prompt, type regedit (this is just a vessel to get to an explorer window). Hit File > Import to open up an explorer window, and navigate to your autoruns installation. Right click and run the EXE as administrator. Next (important) go to File > Analyze Offline System, select the windows directory in the first field, and your user directory in the second (Use this guide for more help: "Analyze Offline System" Feature Added in Autoruns from Windows Sysinternals >> Winhelponline). Finally you can edit your auto runs on your windows install. You'll want to go ahead and pretty much check everything and hit save. Then reboot and pray to the windows gods. Good luck.
