Hello, I have been having screen-computer freezes for quite some time with Mint-12 but not 11 or 10, they worked fine. Control+Backspace and REISUB did nothing. Meanwhile the cooling fans are running at or near full speed indicating a heavy CPU load. I was having to power off/on each time. I have tried different desktops, have spent hours upon hours googling and reading. I tried every suggestion offered or that I read about, did a complete reinstall twice and even replaced my Broadcom 4312 with an Intel 6200 wifi card. I also installed ArchLinux and OpenSuse, dual booting with Mint-12. They also eventually had freezing problems but not as often. I discovered quite a few others are having the same problem from searching various forums. Everyone seems to come up with various reasons, hardware, video, drivers, video/audio players or other software, etc.
The only common theme that I could find was that they are all Linux, running later release Kernels. I read the bug reports and found various reasons offered for the problem and some fixes offered. These were tried but didn't work. I did suspect a link between the wifi carrier dropping out for a second and then returning. I'm pretty sure this had something to do with the lock-ups but I never could find any logs reflecting this as the logs stopped recording when the freeze occurs. However when visiting a relative whose wifi carrier never dropped out, my computer never locked up.
I think there's a problem with the kernel not maintaining system integrity when this or something similar is happening, but not being a programmer I can't prove it. I eventually will file a bug report although I can't yet document anything.
I finally decided to dual-boot FreeBSD which I'm still running and has an up-time so far of 2 weeks continuously on line. During that time the wifi carrier has dropped out & returned but it doesn't affect the system at all.
Does anyone have any other suggestions for solving this problem?
I've been a Mint user since 2006 and would love to continue using Mint full time but I can't put up with using the power button for a reset.
I'm using a standard Dell 1545 Laptop, 200GB Hard Drive with 3GB Ram.
