It's almost certainly a hardware issue. The Linux kernel is usually very
good at oopsing whenever software does something it's not supposed to.
Upgrade to the latest nVidia driver if you think that could be a problem
but in my experience you'll get errors in the logs, X crashes or no
video at all if there's a driver problem. I can't remember an nVidia
card or driver hanging the machine entirely and I've supported studios
with 100s of Linux machines with nVidia cards.
Definitely run a memory test. Are all your fans running? Use something
like Munin to monitor CPU and graphics card temperatures and fan speeds
and see if there's a pattern to when the machine hangs.
Some motherboards have diagnotic LEDs on them that can sometimes give
you a clue what state it's in when it hangs.
Shane.

Hi,
I am gradually being woooed into changing my old mobile and buying an
Android Smartphone so I thought I would buy a dongle to practice on!
I bought a MK 809 II:
http://www.amazon.co.uk/JUSTOP-II-Android-Adapter-Bluetooth/dp/B00AFVO1EA/ref=cm_cr_pr_product_top/279-3924504-9622937
I have read about security issues with "Permissions" on Apps and down
loaded "BBC Weather" app and found it new my exact location!
I am on my internal network but my PC and Laptop were off so how did it
get my position I assume it must have been through my google/gmail
account that I had to set up!?
I did read that I could alter "permissions" but when I downloaded the
apps I had to agree to them.
Is there any way some of these can be disabled?
(I understand there is an app for the apps permissions!)
finally, my BBC Iplayer seems to be flaky. When playing its is OK if I
just let it run but the screen freezes when jumping forward however the
sound jumps forward OK. I left it for about a minute but the screen
remained frozen. I also tried other programmes with the same result.
Has anyone had this problem or is it likely to be H/W!?
Thanks

Either the phone's built-in GPS if you have reception from the satellite, or the database of Wi-Fi SSIDs visible (not just yours) and locations that Google built when they sent the Streetview car round, or a database of cell towers and locations.

Not without rooting and installing third-party stuff. This is something I believe BlackBerry does much better.

Network bandwidth, congestion, insufficient hardware. Try reducing the quality/resolution in iPlayer.

Hello,
You can only alter the permissions that you give to apps if you root your
device. Once rooted, there are several third party options from the Google
Play store that will help you. Hopefully Google will release this as a
feature built into the operating system!
Reasonably good overview:
http://www.howtogeek.com/176968/everything-you-need-to-know-about-managing-app-permissions-on-android/
If you've connected the dongle to the Internet, your location can be found
by your IP address: http://en.wikipedia.org/wiki/Geolocation_software
Thanks,
James

Yes I would definitely run memtest86+ for a while.
Also, running 'stress' (takes a while to adjust parameters to get
reasonable memory usage, VM usage, cpu usage etc.) for a few hours'
run is a really good idea. [it should make machine 'unusuable' while
its' going]. I've had machines with iffy CPU capacitors where
memtest86+ is still fine, but 'stress' CAN crash it...
I have had _some_ weird crash (or at least, no response to keyboard)
scenarios where I've had to resort to setting up serial port console
with serial as primary console for kernel and service-starting
messages, before it fails, so I can actually log the kernel error
etc....

Probably from your ip address. Nothing too 1984!

Thanks, yes, I am beginning to suspect it is hardware based. Thanks for
your suggestions! Looks like I am going to have a fun time getting to
the root of this...
