Hi I haven't been able to use linux for like 6 months I've tried Fedora 14, Debian Testing, Ubuntu 10.04 and now Mint KDE.

Whenever I boot any distro my laptop acts randombly, it gets to GDM and it freezes, or it lets me login and then freezes or works really slow, even through the shell.

The only thing I could figured is to insert acpi=off on the boot commands googling around, and there it boots.

My problem is that it gets overheated, I can't use any porcessor policy and I can't suspend my laptop with that boot line.

I don't why this started to happen when I had Ubuntu Jaunty I had no troubles. Pleaaase any advise.

You might also try the kernel options: noapic nolapic

I had to use these to boot an old Dell Inspiron 1501

I tried that but it makes no difference, thanks anyway.
