Not really sure what's up. A couple of times my laptop has frozen. Either the program won't respond or won't launch. I've had to do a fsck check each time to get back in or I'd be stuck in initramfs, unable to log in again. (My phone had not packed up so I was able to google this info.) Anyone got any ideas?
I've had a couple of times when Firefox has hogged the processor so effectively that it felt like the whole thing had hung and in one case I too had to use the power button to turn off and reset everything.
Do you run Firefox? It's Javascript from rubbish websites that causes the problem in my experience.
Yes it's usually the browser and sometimes a recently installed brower plugin.
If you wait the Out of Memory Killer (OOM) should kill it.
There are also some key sequences which may help (But not all distros have these enabled).
