[Nottingham] Arch always on system freezing

[Martin]

Immediate things to check are:

Dust?!
Failed cooling fan?
Internal/CPU overheating? (including the PSU or power adapter?)
Try running Memtest86 for an hour or two...
Any disk errors still...?
Full disk partition??
Disk failure??

Hope that gives some clues.

Let us know for further details??

Good luck,

Cheers,
Martin
