Hi,

I have a reasonably new PC which ran with no problems for around six weeks after initial install of Arch, but then about two weeks ago it started locking up randomly. I can't see anything obvious that is causing it to lock up. Sometimes it does it while I am actively working, and other times it locks up overnight (I tend to leave it running continuously).

...

Without more, I have seen this with faulty hardware, such as faulty ram modules, or PCI cards malfunctioning.

The standard way for debugging things is to take out hardware until the problem stops.

Side note: have you any idea of temps when this is happening?
