Mint freezes during loading
Linux Mint 7 was working perfectly.
Then I had my motherboard replaced with exactly the same model: ASRock P4i65GV.
Now after Grub, as the OS is loading, it freezes before I get to the bit where I'm asked for my username.
Same with live CD.
No joy in compatibility mode either.
Downloaded and burned new live CD. Same thing.
Tried with Ubuntu live CD. exactly the same.
What can I do?
(Non technical language please?!)
