Dell Latitude 3120's

[Buzzer90]

Anyone got any Latitude 3120's?

 

We've had 12 come into us over the past 2 days as they won't boot to Windows. POST fine with Dell Splash screen but then screen goes 'off' I say that as laptop is still powered on but just a feint blue/purple display.

 

Some really bizarre things like HDD's working in Spare laptops and Spare HDD's working in original laptop but original HDD in original laptop it doesn't like, although it will boot fine in Safe Mode.

 

BIOS updated & also tried rolling back but no joy.

 

Slightly concerning as we have over 200 of these...

 

Thanks

Graphics Driver it turns out, had tried updating but needed rolling back...
