Problem: System crashes during power-on
Possible causes. First, for a computer to boot,
the CPU must be properly installed, RAM must be installed, all power
connectors have to be attached, and the keyboard must be attached. Needless
to say, if any of these items are not connected properly they could
cause your problem.
Another cause of the problem could be your motherboard's BIOS is not
configured correctly. This is resolved by comparing your settings to
those that are recommended by your computer/motherboard manufacturer.
A third cause of the problem could be a malfunctioning component, such
as an unstable or overclocked CPU, a malfunctioning power supply, or
a shorted motherboard.
How to figure out what the beeps mean. The beeping
can be interpreted by what type of BIOS you have. If you have an AMI
BIOS the power on self test (POST) beep codes can be interpreted at
If you have an Award BIOS you can find information on their beep and
POST codes at the Phoenix
web site (Award and Phoenix merged in 1998).
Not only do the above documents provide an explanation of the beep codes,
they also provide good information on how to troubleshoot and resolve
problems, and I recommend you read both documents.
Additional Help. If you get nowhere by yourself,
its time to turn to a professional. Computer repair shops can obtain
additional information on POST failures with diagnostic equipment. It
might help to ask them the question, "Do you have equipment which can
read BIOS POST codes?" before you hand them your computer.
getting a home-built Athlon system to boot.
Hello, I am building a complete new system based on the Athlon processor.
When I turn the system on I get no response -- fans come on, CPU warms
after a bit of time and hard drive comes on. There is power going where
it is supposed to.
The only components used that are not on the Athlon preferred list of
AMD are the case, which is still slot1 compatible, 250watt ATX power,
and the SDRAM, which is Micron P133 128meg (the serial number is not
listed with the other Micron compatible SDRAM listed).
The video card is an ATI all in wonder 128. I tried removing and replacing
a couple of times, still no luck. I have no display on my monitor. The
keyboard I am building with is an older one using a p2 adapter till
my new one gets here but I don't think that could cause no display,
not even a cursor on the monitor.
I was extremely careful when assembling, have done this once before
(4 years ago with Motherboard and CPU) with my older system, and have
always upgraded cards and components myself, yet never had a problem
like this. Motherboard (FIC SD11) is mounted correctly (on a rear slide
out type case).
SDRAM is Micron SDRAM # MT48LC8M8A2TG. The recommended Micron SDRAM
has a -8E at the end. Not sure if it is different than what I have.
I disconnected all drives before starting up the computer, still no
screen (stays on standby setting).
I tried other monitor, with same result. Tried older PCI video card,
no change. My only other thought is....could the Motherboard or CPU
be dead on arrival? or, am I doing something wrong? Any, and I do mean
Any, suggestions would be greatly appreciated.
InfoHQ Answer. I have a couple of thoughts on this.
First, I believe this is not a video card issue since you tried different
cards with no result. Also, the likelihood of the motherboard or CPU
being damaged is very low if you handled them correctly. So assuming
the video card is OK, makes me believe that your computer is not getting
to the DOS memory post test.
The keyboard issue is not a player as the computer will pass the memory
post test before failing the keyboard check, and this would be reported
on your screen. After reading several reviews on the SD11, and visiting
the FIC and AMD sites, I have a couple more thoughts.
1. I think the RAM you bought could keep the computer from booting.
There seems to be specific requirements on the FIC site and I can not
identify the RAM you bought. The AMD web site specifically states that
unbuffered SDRAM must be used. Can your RAM be exchanged for one of
the recommended RAM part numbers? Before you return it, try reseating
it a few times.
2. Another thing that could keep the computer from reaching post is
the accessory case connectors not being attached correctly. Make sure
they are connected to the correct pins on the motherboard and that they
all face in the same direction or you could be crossing the pins.
