ETD.sys has to do with Elantech Smart-Pad.
means the driver couldn't access or detect the touchpad, so it failed to load.
"error 0x8000ffff'' simply means the system was not able to restore for some reason.
"This problem occurs because certain files are not replaced correctly if a file conflict occurs during the restore process. Be aware that System Restore may have failed even though the "System Restore has completed successfully" message is displayed."
There's a workaround there, but I doubt it applies to your situation.
I suspect a growing hardware problem, first with the touchpad, then with the video.
Can you access the BIOS and see it on the screen?
I have taken my laptop away and today tried to power it on (without connection to display/power) and I was greeted by a BSOD (I am running Windows 10) - the BSOD error message said ''DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS (etd.sys)''. I tried rebooting, safe mode etc, with no luck, the BSOD kept reappearing, so I then went on to restore to a point on July 30th, this operation seemed to succeed until the final part, where it said ''error 0x8000ffff'' and that no changes had taken place. Annoyed at this I powered down my laptop.
Later when booted it back up, the system seemed to start up normally, but the display was not turned on (completely black, no backlight) the fan was on and the lights were also on. I tried the removing battery method and nothing changed. I left the laptop off for a prolonged period of time and it still did not work, is this something to do with the display drivers?
I would really appreciate some help as I am English, but staying in France currently and need the use of my laptop quickly for a project,
