Anyway after that ordeal I have to deal with this problem and it seems many people found the solution by accident or pure luck.
Here are some things I have tried:
Start in Safe Mode
In Last Known Config
Disable Driver Signature Enforcement
Start Up Repair
No PS/2 Port
Im using win 7 ultimate x64, dell xps15z. I have Dell Safety Recovery Backup but not sure if it wipes my memory away as it needs my files to be backed up? Im saving that as a last resort.
Oh and system restore points are a no go, I dont have any.
*Not working in Welcome Screen, Safe Mode and etc.
Keyboard works in bootable usb win 7 but not mouse
Both working in OS own startup repair
