27 inch I mac starts up fine but when it gets to the login screen I can't select anything. Mouse pointer moves around. Have tried different mouse, wired and wireless. Started up in safe mode but that just brings me to the login screen with Safe mode in red at the top right, still can't select anything. Have got slightly further and been able to enter password some times, that opens user but then cant select anything. I have re set the Pram and the SMC but no difference. Started in recovery mode and done disk utility all fine not problems found. Updated to latest Mac OX El Capitan 10.11.05 I think.
Any Ideas as to what might be causing the problem. Any help would be much appreciated.
