all the dust from the inside.<BR>> 3) Pull off, lubricate (electronics
lubricant) and reseat all cables.<BR>> 4) If your motherboard batter is
more than a year old, replace it.<BR>> 5) Disable (open circuit) your
reboot button, and replace your on/off button<BR>> with a simple,
non-lighted doorbell button.<BR>><BR>> I learned #5 the hard way -- the
reboot and power switches that come with the<BR>> case can go intermittent,
and not just intermittent open, but intermittently<BR>> close without
pushing.<BR>><BR>> None of the preceding is diagnostic in nature, but
given the rarity of the<BR>> symptom, if the log files don't have something
telling, the preceding are<BR>> probably the best use of your
time.<BR>><BR>> HTH<BR>><BR>> SteveT<BR>><BR>> Steve

folks,<BR>I've got a few more restarts. I have switched off gdm so
Xserver <BR>failure should not cause a restart. The box seems not too
hot, but the <BR>problem might be connected with power, all restarts
occur after few <BR>hours of heavy load.<BR>There is nothing in logs. It
looks like restart button was pressed.<BR><BR>My box is still under warranty
so I can not play with hardware. <BR>However I should like to
understand how it works. In particular I <BR>wander, is it
possible that some user program cause immediate restart? <BR>Is it
kernel which does it, or BIOS or whatever?<BR><BR>CPU: AMD QUAD 9750<BR>MB:
