Problem. Mint 7 64bit crashes after about 2-3 mins *unless* I disable ACPI in BIOS
I have an Athlon 4000+ 64 processor on an MSI K8T Neo 2 motherboard with 2 gig ram. Video card is a NVidia Geforce 7800GS. Before I installed Mint I had a Windows XP and OpenSolaris dual boot system. (I added MInt as the third bootable OS). The XP and OpenSolaris were working fine. But when I booted Mint for the first time it just crashed after about 2-3 mins - the display just locked. I thought that it might be video card related, but I found that when I disabled ACPI in BIOS Mint ran OK.
I'd obviously like to have ACPI working (it's nice that the PC will turn itself off) and since XP was installed with ACPI on, it doesn't like ACPI off. It's a real pain having to go into Bios every time I want to use Mint. I've tried adding the NOACPI or ACPI=off to the kernal, but still no joy.
Does anyone know what might be causing this (as it doesn't seem to be a widespread problem) and more importantly what to do to fix it?
PS I have been running Mint on a separate box for the past 4 or 5 months without problem.
