I've been using Linux Mint since version 3 on an old Dell Dimension 4500S, and I've never encountered any problem like this before. When I put in the live CD, it runs normally up to the point that it reaches the loading screen. A little bit of the loading bar fills up, but then it just stops right there. When I tried disabling my Geforce 4 MX4000 and using the onboard graphics hardware built into the Intel 82845G chipset, I was able to boot from the Live CD and install Mint.
What is the cause of this issue, and what can I do to fix it? I'm sorry if this is a stupid question, but I really haven't been able to find a solution for it.
