Thanks so much for the reply trukntigger I really appreciate your time.

your help would be massively appreciated as i am totally stuck here and grudge giving acer any money especially as the fault seems to be at there end. i am not the most tech savy but with a little guidance i should be able to do most things. is there a way i can just delete the elan driver and stop it from auro updating and just use an external mouse and disable the touchpad altogether? seriously am struggling with this so any help or suggestions would be greatly appreciated. seems crazy to think this computer was working fine a few weeks ago and now becuase of a dodgy dirver i almost cant even use the computer. I have read a few others with very similar problem as me but i am unable to find a fix and tbh i am running out of ideas altogether. I have also tried to revert back to windows 8 as apparantly my system is'nt recommended for win 10 but the windows 8 version was oem and acer want to sell me the media to reinstall windows 8 again even though i paid for win 8 when i purchased he laptop so i wont be paying £50 for windows 8 that i already have bought. i have contacted both microsoft and acer and haven't got anywhere with either of them microsoft blame acer and acer want me to pay for support which i refuse to do. i have tried system restore and also tried a fresh install of windows 10 and the laptop works for a short time after but then the driver is automatically updated again then i get the same issues. i have tried to delete the elan driver but it just automatically updates and i cant stop windows from updating this and once it updates i get BSOD again. recently windows updated the driver for the touchpad and since then i have had all kinds of trouble and now get BSOD most times i try to boot up windows with the error 'page fault in non paed area' then it says 'ETD.sys' which is the driver for the elan touchpad.
