Hi,

Please expand this question. Where does it crash. Software (sorry to say that) WILL crash. Of all crafts, writing software is the most non-automated. People will make mistakes, thus the software they write will...crash. Fact of life.

If your question is about avoidiing this, then ... sorry.

Did it crash? Okay, then provide some details here.

Hardware does not determine to crash. There may well be stuff that may not be too "Linux Friendly", but there is a list for you to consult...

We're here to help.

By the way, welcome to the forum.

Thor

Okay, so, it's occasional freez-ups. That's unpleasant. Let's determine what happens. Is it a freez-up, or an over-imposed on system that needs time to work some things out so the rest has a freeze. To do that, start the program "top" in a console and leave it there. Keep looking at the average load the system endures. What are the peaks?
If the console freezes up, whances are that the X could be corrupt.

By the way, have you done a sys-up lately?

Yes they can:
  • bad RAM (check each stick with memtest, individually)
  • bad hard drive (use smartmontools to monitor)
  • bad CPU (test with something like prime95).

Running out of RAM will result in what feels very much like a system crash too (use free to check how much is being used).

Okay, well I meant to say that you Xorg could be the one that crashes. What's underneath should keep going happily...there are not a zillion ways to find that out. Either the Xorg crashes, and the (graphical) desktop freezes or the wholsemachine stumbles.

In the latter case, some info should emerge from the suggestions dugan made.
Okay, let's attempt to get the Xorg out of the picture for a second and try to run some of these tests...
Hmm, what's the best way to go about this? Try (if possible) to download/burn a Live CD. Boot the system with that. If it is the OS (or a portion of it), we'll at least have them out of the picture. A liveCD should boot in memory and leave the internal hard drive alone. open a console and run the tests dugan suggested. Let's see if it's the box or the OS...

By the way, "sysup" is a word I picked up (somewhere) meaning System Update...
Maybe a first step (if you have not yet done that)

More questions? Post'em here

Well, more memory will make it all run faster...up to a point where there's more than enough memory. More memory is not a rocket that will speed things up
But I'm beginnig to believe that a harware "swap" could help...possibly some hardware is either faulty or just wrong for this system. To clarify furter. If you have one slice of ram, and add a second one that is "not compatible" the system could in effect run slower or even die on you.

What does the memtest reveal?
