When I go to device manager it has little yellow exclamation marks next tio the 2 cd drives installed.
Anyone got any ideas?

I had that exact problem a few years ago and ended up having to get a new drive.
My PC wouldnt see it in explorer and I had the exclamation mark in device manager.
The fact that its not recognising an ext drive is strange.
Maybe a motherboard problem? Im not too sure to be honest.
Reformatting and reinstalling might be difficult if you cant see a drive.
