|ok, soon after my original post, the reboots become more and more frequent the |
longer i had the pc turned on, so naturally put it down to overheating.
i tried one ram stick at a time (from 4 1gb sticks) in different slots - no
all fans are running well.
i took the entire system apart, cleaned everything, re-applied arctic MX-2 to
the cpu and north bridge. south bridge has a thermal mat which seems fine.
after putting it back together again, the reboots happen less often, but are
i tried memtest86 with each stick in for about an hour while in different
slots and all reported fine without rebooting. when i used 3 or 4 sticks
together it started rebooted after a about 2 hours, but still reported no
errors to the ram, so again i think something is overheating. i had the HDs
and dvd drive unplugged during the mem tests.
my cpu temps are in the low 30s, the system temp is about 40-ish i think.
the voltages are reported as normal by the mobo.
the pc reboots more often when in windows due to more stress on system, but
i'm convinced its not software related due to reboots during startup and
pcmark ran once without problems, and again with a reboot.
3dmark caused many reboots often, which i guess would point toward the GFX,
which brings me to another thing.... i recenlty started using an s-video lead
to play old games through a crt tv. i noticed sparks when the adapter touched
the metal exposure of the GFX card at the back of the computer!
could that have damaged the card with electrostatic charges?
also, getting the lead plugged in required some wobbling and movement of the
gfx card while the system was running....
well so far i think its down to the GPU or PSU and i'm trying to get hold of
someone's spares to test them.
what are other people's thoughts on this?
