So I have a Dell Studio Core 2 Duo T5750 with ATI Mobility Radeon HD 3400 sereis and PM965 intel chipset. I have been trying various distros to boot, but they all go to boot1: /boot, or cdboot: done and don't move from there. I don't get any farther than that, no vader, no command line, nothing. Can anyone give me an idea what the problem is and how to fix it?

It goes Dell logo...CD tries to load up, CDboot: done freeze
