I run XP under Bootcamp on my Macbook. A few months back it was dropped and the screen smashed. I've only just installed a new one, and it was running fine until I connected my firewire soundcard. Since then it's sometimes refused to start, or required I hold it at a certain angle. If I move around with it on my lap, it triggers the BSOD. Now, when I boot-up in OSX the same happens. It can be fine, but the even gentle fiddling can provoke the equivalent MacOS crash. Obviously it could be related to my screen installation, but some of the messages appear to be related to other hardware issues. Before I complain to my retailer that the screen isn't appropriate (having already checked the connection is fine, many times), would these be indicative of the original accident having caused hardware damage to the rest of the machine? Many thanks for your help!
