k7s6a random reboot

External Since: Oct 17, 2003 Posts: 1

I've used the k7s6a motherboard for a long time. It works fine, but
sometimes it will reboot spontantaneously. I is doing this regardless of
what other hardware or operative system I use. Also the screen will
sometimes suddenly turn black - for about one second, and then come back
to normal. The reboot is immediate. The computer can be turned on for
days without neither the sudden reboot nor the black screen appearing.
When I stress-test the computer with burnk7 and similar programs, it
will not crash, and temperatures seem to be fine. What could be the
caouse of this intermittent problem? My own guess is that it has
something to do with cpu or memory, but I have noticed no correlations.
I'm using an Athlon Xp 1800+ cpu, clocked normally at winter,
underclocked at summer because otherwise it would be unstable.

Mats,
It SOUNDS like a cpu temp problem, but you say you monitor the cpu
temp......my next guess is power supply. What are you running for power? I
have found the 400 watt Allied power supply has great specs, (not just a
bogus 400 watt rating, example is some of the cheap 400 watt pwr supp. like
compUSA) and it is on-sale at newegg for just 30 bucks, I have 3 HD's ( 2 80
gigs and 1 160 gig so they do draw some power) 3 optical drives, 3 case
fans, (some with leds) chipset fan, cpu fan (CPU fan is a DR thermal I
highly recommend, quiet and it cools better than a 2X expensive all copper,
2 TON, (read heavy) jet engine sounding heatsink I had before) and 2 cold
cathode lamps, running on one with absolutely no problems what so ever, and
the CPU is overclocked.
(I am not a newegg rep. just a very happy customer)
Let us know what kind of power supply you have.....and the complete machine
specs. would be nice too....it could be memory, but without you running
something like memtest it is not possible to know, I believe the prog is
memtest86 and it runs in it's own environment (boots from a floppy) and will
most likely rule out any mem probs. try it...too.......let us know, and I'll
try and help! Good Luck.
