Abit NF7-S v2.0 doesn't post...

Hi,

Just stuck a new system together for my girlfriend and it doesn't work

All the system fans spin up including the graphics card's and the hard disk
spins up. There is no video output, the optical mouse doesn't light up when
plugged in to either the PS2 or USB ports. The keyboard lights flicker when
switching on at the PSU but there's no sign of activity when pressing the
switch at the front.

Once the system speaker beeped at a regular interval on and off. It seemed
to be about 2 secs interval between beeps. At all other times the system has
not beeped at all and could only be powered off by the PSU switch.

I have had the time to test the memory in my machine and it works fine so it
can't be that...

The fan is spinning on the graphics card so I presume it's working ok and
seated ok but will try test it on my machine.

Only other possibilities are a duff mainboard or a duff processor.

I've tried various combinations of the jumpers and connectors etc and using
the clr cmos jumper but no joy. I have also tried using only one DIMM and in
various slots etc.

I have no fan connected to the chassis fan connector as the case doesn't
have one. Would this cause this problem?

System spec

Abit NF7-S v2.0
Sapphire ATI Radeon 9600 pro fireblade E
256mb X 2 Twinmos cl2.5 PC3200
AMD Athlon 2500+ XP Barton
Antec 400 watt Psu.
Maxtor 120gb 8mb cache IDE.

Any help would be greatly appreciated...

Thanks in advance

Suggest you try a bench test with ONLY the following bits
(take em ouuta the case and assemble them on a table)

power supply / mains lead
mobo
memory - 1 stick
cpu with heatsink / cooling fan
gfx card
monitor
keyboard
small screwdriver (to temporarily short the two pins on the mobo that the
case power button normally shorts)

I usually sit the mobo on the cardboard box it came in and have the gfx card
bracket hanging over the edge of the box.

If that lot posts stating no drives found then you know the problem is
elsewhere.
mobo to case short or duff / incorrectly connected drives are the usual.

HTH, it usually does for me!

Try connecting the cpu fan directly to the psu, not the motherboard.

Try removing the cpu or memory completely, and powering up, that should
start it beeping, which will tell you the bios/chipset is at least
functioning.

The slow beeping you heard I believe is either memory or cpu error. If you
have another cpu/memory to try, try them.

Are both the red & green lights on on the motherboard?

Yes. Red light on while in standby and another light turns on while powered
up. Not sure if it's green though would have to check.

One extra question so I have *one* less thing to worry about. Will the
system have heated up enough to melt the thermal compound on the
Coolermaster heatsink?

I've just had the same problem, I think there may be a dud batch in the
uk. I've spoken to the guys at Abit tech support and apart from a
problem with the cpu fan header not reading rpm's properly from some
third party fans there no other known issues.

Check if there's any power coming from the chassis fan header, mine was
total dead. Get it back to your supplier and get a new one, that's what
I had to do.
Where'd you get it, as a matter of interest ?

if you have another stick of RAM - try booting with it - do not use the twinmos
- it may require a BIOS update.

Any reason why this would be?!

Tried a minimal system. Stuck the CPU fan on the PSU fan connector (as I saw
mentioned elsewhere in order to make it detect no CPU fan) and the system
did not turn off. I also tested with a different graphics card but forgot to
try the board with no RAM whatsoever.

I believe you are correct about the bad batch steve. I only hope a
replacement motherboard solves the problem, it's really annoying :-S

Thanks everyone...

And would this stop the auto shut down when no CPU fan is plugged in?

TIA....
