Hi,


Mobo: MSI Diamond K9N
CPU: AMD 64bit X2 cpu
Mem: 4G OCZ mem (2x matched pairs)
HDD: 2 WD Raptors
Case: Antec P150 with original power supply (Neo H3)
GFX: MSI nVidia based GFX (I think it was 9700GTX)
other: white brand DVD RW+-



The problem:
------------
Lately I begin to have several times a "freeze" of my system. I mean, I still have a clean view, but everything is frozen. I can't move the mouse, can't kill gdm, numlock light stays on, ... The only thing I can do is press the reset button.

I had it first when I upgraded to ubuntu: Feisty. So I thought like 'damned buggy release', so I reinstalled Edgy... But that seemed not the solution because the freezes kept comming.

A few nights ago, I had an 'immediate shutdown' of my computer. One moment I was coding, next moment I was staring at a blank screen. The light of the powerup-button was slowly blinking blue (standby mode?).

I couldn't get my computer running again normally at that point. So I turned it off (removed powercable and stuff). Plugged it back in, and it would start again. But I didn't have any screen anymore.

Now with the MSI mobo there is some kind of led-tool added so you can see what part of the bios it is at in the initialization process.
First reboot the leds said 'processor dead', next reboot it said 'mem dead', then it said 'gfx initialisation', ... Sometimes even it said 'no problem at all'.

I tried to change all the components in the computer with a similar one from work, but to no avail. Then I plugged in back all the original parts, and now it started without a problem...

So I thought ... Weird, but OK. I went on installing Edgy, but yesterday night again I had 2 freezes.

It seems most likely to happen when I'm not arround (like eating or so), or when I'm working in a Win2K on VMPlayer.


The question:
-------------
What could be the problem? I for myself think it might be the mobo which has gone fubar, but what do you people think?


Another question is if it's possible to send ACPI (those energy-saving things?) commands to the hardware?
I am suspecting that my motherboard doesn't respond correctly to them, so I want to test them to be sure.


Thanks a lot!

I'm not familiar with MSI boards. Heck, my mobo is a 5 year old KMA. From your description it sounds to me like overheating. You say you've tried replacing parts with ones from "work". Did that include memory, power supply and cpu fan?

Yupz,

Replaced everything in the computer (took me a whole afternoon) to check everything one by one.
Fan, cpu, mem, psu, but all on the same motherboard...
