Windows 7 professional freezes at login screen

[dragon1x]

It just froze on the welcome screen and wont even let me log in (enter my password) or even let me move my mouse or whatsoever.
Toshiba m305-s4910
My laptop came with windows vista premium preinstalled and I did a clean installed of windows 7 professional.
I have tried startup repair. Automatically fix problems that are preventing windows for starting.
I have tested the hard drive for problems and is ok.
I used the System Restore to roll back to an existing restore point.
I have unintalled and reinstaled windows 7 professional three times.
I have used CleanMyPC Registry Cleaner to clean the registry.
I have started Windows in Safe Mode.
I stopped windows defender and windows firewall services.
Drivers are up to date.
I have loaded the last known good configuration of windows 7.
I've tried many of the above mentioned things but only work for a short period of time.
Some time I can log in but others times windows freezes always at login screen
Regards.

If it has persisted accross clean installs it has to be hardware.
