8KNXP Unstable

I am getting random reboots on my 8KNXP (rev 2) board. I am also getting a
very strange effect where Windows XP looks to have hanged for about 5
seconds then the screen flashes black for a second and everything returns to
normal. I have a 350W Enermax power supply and I have a suspicion that this
might be the cause of the trouble as I'm unsure if this has enough power. I
think this as the system seems to reboot when I access the CD-Rom but on
another occassion it reset when I was re-arranging the start menu. I have
the following system

Gigabyte 8KNXP (Revision 2)
1GB Corsair TwinX memory 3200C2 running at 400MHz (Timings 2.5,3,3,6)
Zalman 7000A full copper heatsink
nVidia 5200 GeForceFX - 128MB
2 x Maxtor 80GB SATA Drives (Raid 0 through Intel SATA raid controller)
1 x IBM 40GB UATA100 Drive (Through 100ATA Controller)
1 x 48x IDE CDRom (Through 100ATA Controller)
1 x SCSI DVD Rom
1 x SCSI CD Writer
PCI Cards - USB 2.0 Card, Adaptec SCSI Card, Internal Modem
Windows XP (Not SP1 getting it tomorrow)

Does anyone know if this PSU is poweful enough for this system? The crashes
are always reboots and have never happened when playing 3D games. I have run
MemTest86 for 4 hours with these memory timings with not a single error.

Thanks for any help

I've had crazy things like this take place and reinstalling Windows with a
complete reformatting fixed everything.

As for reboots, right click on 'My Computer' and select 'Properties'. Choose
the 'Advanced' tab and under 'Startup and Recovery', click on 'Settings'.
On the dialog that follows, uncheck 'Automatically restart' under 'System
Failure'. This should stop the rebooting. However, there obviously is a
reason it's rebooting. You'll want to find out and fix it.

Thanks for the help I'll have a look when I got home. It is very strange as
I played games last night which should really tax the system and it stayed
stable for 2 hours.

I'm afraid I can't trace that to anything specific, sorry Colin. You could try posting
that in the WindowsXP.general newsgroup where the pros hang out.

Colin,

Take a look at this:

http://www.eventid.net/display.asp?e...&source=system

and this (hot totally related, but tends to indicate hardware).

http://support.microsoft.com/default...b;en-us;817197

Faulty memory can cause *all* types of fault, but memtest86 indicates it
seems ok?

A 350 Watt PUS with all that stuff may not be enough. Try removing say all
SCSI devices and other optional stuff.
You don't say what type of adaptec SCSI it is. Some were extremely sensitive
to PCI bus speed.

If that fails try a general h/w fault diagnosis approach: strip to "minimum
XP" and test.

If thats OK, then progressively add h.w back in until the fault reappears.

- Tim

The SCSI card is an Adaptec 2940UW an old one.

I managed to get the problem pretty reproducable. If I try to read 2 cds at
one. One in the SCSI CD Writer and the other in the IDE CDRom then I get the
crash. Apart from that I ran it through about 10 games and various
benchmarks last night and it only ever fell over with 2 CD Roms being
accessed at once. This does seem to me to be the PSU so I'm going to strip
back to one CD Rom and take out the SCSI card and see how it goes.

The system seems to be very sensitive to reordering the start menu, I get
black flashes sometimes and icons jumping to the desktop among other things
but I think this is something else unrelated.

Colin,

The SCSI cards I had trouble with were the 2940's (not U or UW). I thought
the U and UW addressed the problem.
Is your SCSI bus terminated correctly?

IE if you have no externally connected devices, then termination should be
on on the card so long as the card is at one end of the SCSI cable, and
termination should be on on the very last physically attached device.

As for the flashing, dunno. Could be virus, spyware, graphics driver, bios.

I am getting random reboots on my 8KNXP (rev 2) board. I am also
getting
a
very strange effect where Windows XP looks to have hanged for
about
5
seconds then the screen flashes black for a second and everything
returns to
normal. I have a 350W Enermax power supply and I have a suspicion
that
this
might be the cause of the trouble as I'm unsure if this has enough
power. I
think this as the system seems to reboot when I access the CD-Rom
but
on
another occassion it reset when I was re-arranging the start menu.
I
have
the following system

Gigabyte 8KNXP (Revision 2)
1GB Corsair TwinX memory 3200C2 running at 400MHz (Timings
2.5,3,3,6)
Zalman 7000A full copper heatsink
nVidia 5200 GeForceFX - 128MB
2 x Maxtor 80GB SATA Drives (Raid 0 through Intel SATA raid
controller)
1 x IBM 40GB UATA100 Drive (Through 100ATA Controller)
1 x 48x IDE CDRom (Through 100ATA Controller)
1 x SCSI DVD Rom
1 x SCSI CD Writer
PCI Cards - USB 2.0 Card, Adaptec SCSI Card, Internal Modem
Windows XP (Not SP1 getting it tomorrow)

Does anyone know if this PSU is poweful enough for this system?
The
crashes
are always reboots and have never happened when playing 3D games.
I
have
run
MemTest86 for 4 hours with these memory timings with not a single
error.

Thanks for any help

Didn't actually think about the termination issue. I did change the
configuration of the SCSI chain when I reinstalled my system but I am
certain the chain is terminated correctly at both ends. The funny thing is I
can run the SCSI CD Writer and the SCSI DVD Rom on their own without a
single problem but the system crashes every time I run 2 units together.
From this I imagine it is drawing too much power on spin up of the CD unit.
From what I understand with the number of units I have in the system and a
3GHz chip my 350W PSU doesn't have enough juice to power everything in the
system at maximum load.

Colin,

The SCSI cards I had trouble with were the 2940's (not U or UW). I thought
the U and UW addressed the problem.
Is your SCSI bus terminated correctly?

IE if you have no externally connected devices, then termination should be
on on the card so long as the card is at one end of the SCSI cable, and
termination should be on on the very last physically attached device.

As for the flashing, dunno. Could be virus, spyware, graphics driver,
bios.

The SCSI card is an Adaptec 2940UW an old one.

I managed to get the problem pretty reproducable. If I try to read 2 cds
at
one. One in the SCSI CD Writer and the other in the IDE CDRom then I get
the
crash. Apart from that I ran it through about 10 games and various
benchmarks last night and it only ever fell over with 2 CD Roms being
accessed at once. This does seem to me to be the PSU so I'm going to
strip
back to one CD Rom and take out the SCSI card and see how it goes.

The system seems to be very sensitive to reordering the start menu, I
get
black flashes sometimes and icons jumping to the desktop among other
things
but I think this is something else unrelated.

Colin,

Take a look at this:

http://www.eventid.net/display.asp?e...&source=system

and this (hot totally related, but tends to indicate hardware).

http://support.microsoft.com/default...b;en-us;817197

Faulty memory can cause *all* types of fault, but memtest86 indicates
it
seems ok?

A 350 Watt PUS with all that stuff may not be enough. Try removing say
all
SCSI devices and other optional stuff.
You don't say what type of adaptec SCSI it is. Some were extremely
sensitive
to PCI bus speed.

If that fails try a general h/w fault diagnosis approach: strip to
"minimum
XP" and test.

If thats OK, then progressively add h.w back in until the fault
reappears.
