Just a note - I had the hanging / freezing thing as well going on. On a tip from a friend, I upgraded my kernel to 2.6.33, and it's been stable for 2 hours now, the best it's been since I upgraded to Mint 9 a few days ago.
You can get the updated kernel at http://kernel.ubuntu.com/~kernel-ppa/ma ... 3.4-lucid/.
It's not all down to the software
The hardest problems to diagnose are those that occur apparently randomly, especially if they lock up or crash the computer without warning. When the crash occurs at the same time, or using the same software, you have an idea who to blame, but if it is truly random it may well be hardware. The most common hardware causes of such problems are overheating, faulty memory or poor power.
It's no use thinking "this doesn't happen in my other OS, so it must be Linux's fault" because different systems work the hardware differently. For instance, Linux uses memory more aggressively and will experience instability due to faulty memory before Windows starts to show symptoms. Fans and heatsinks become gradually blocked with dust and other crud during a computer's lifetime. Try blowing it clear with a can of compressed air. Installing lm_sensors (your distro should have it) will let you monitor CPU and case temperatures, and a system monitor like GKrellM will display the temperatures on your desktop.
Laptops don't lend themselves to being opened up for a good blow, but you should check the various vents for any blockage. One area where laptops are fairly safe is power, since the battery ensures a clean steady supply. Desktop power supplies are another matter, especially the cheap, unnamed ones that are included with lower-priced cases.
Built down to a price, some barely meet their specs when new, so try a different PSU in your computer – you may be surprised by the difference it makes. Dirty power can damage your hardware and data, so saving money here can be a false economy whereas good-quality PSUs can go on for years. If you live in an area with unreliable or dirty power, a UPS (Uninteruptible Power Supply) may be a worthwhile investment. Surge protectors don't protect against power reductions, only surges.
Testing memory is easy, if time consuming. Most Live CDs include Memtest86, which does exactly what it says. You need to boot into Memtest86, because it can only test memory that isn't in use, so you don't want a full OS running. Let it run through its full set of tests at least twice, preferably overnight. The longer you can leave it running, the more certain you can be that your memory is OK. If you see any errors, at least one of your memory sticks will need to be replaced.
