windows update

hi guys

hope I'm in the right forum but my inspiron 7746 keeps freezing as soon as I try to open any apps or internet, there was a windows update and when my computer came back on the keyboard would not work so I did a system restore which resolved the problem however 24 hours later and I cant do anything after the initial log in screen.

just performing a re-install so fingers crossed.

does anyone know if dell warranty covers software issues only had the laptop 6 months

any help would be grateful

regards
