Quick Trouble shoot tips
Video (no display) related issues
I built a new computer system using a Soyo board and nothing happens when
turning it on, no video and no beeps from the PC speaker. What is happening
and how can it be fixed?
No screen and no beeps mean that your CPU and motherboard do not work at all. It
could be that the CPU is not seated correctly or that a component on the M/B is
grounded (shorted) with the case. Also make sure to check the voltage setting
switch (110V/220V) on the back of the power supply. To isolate the problem do
the following:
1. Press and hold down on the “Ins”(insert) key while turning on the computer
until you get video. If you do not get video then,
2. Double-check jumpers setting on you motherboard and remove all add-on
cards, unplug all hard-disk and floppy-disk drive cables and see if you can hear
some beeps. If you still do not get any beeps, then try putting the motherboard on
the table (to isolate it from the case) with the CPU and speaker only, and give it one
more try.
I hear a series of beeps and I do not get anything from my monitor. What
could be wrong?
The following lists some basic beep codes and their possible meanings:
•One long beep and 3 very short beeps - The video card is not detected by
the motherboard. Please re-seat your video card. If you are using an AGP
card, please push your AGP card down real hard. You may have to push
VERY hard without the AGP card mounting screw. Make sure not to
insert the card the other way around.
•Continuous beeps –One or more of the memory modules is not seated
correctly in its socket.
My PCI VGA card works fine with my system, but when I put in a new AGP
card, it does not give me any video. Is my AGP slot bad?
This is a common problem with AGP video cards. The reason is that your AGP
card did not get seated into the AGP slot fully and firmly. Please push your AGP
card down into the socket real hard, it should snap twice. You may have to unscrew

SY-7VCM Quick Start Guide
16
the AGP card to allow the card to go further down. Do take care not to damage the
card by using too much force.
I get distorted video my AGP card right after I save my bios. Why is that?
The cause is likely that your AGP card is not running at the correct bus speed. To
fix this, please clear the CMOS via JP5 and if it still does not work, please upgrade
your motherboard bios to the latest version.
BIOS Issues
Where can I find the BIOS revision of my mainboard?
It will be displayed on the up-left corner on the screen during boot-up. It will show
as your board type followed by the revision number, such as 5EH_2CA1 (meaning
revision 2CA1 for the SY-5EH board) or 6BA+ IV_2AA2 which means SY-6BA+
IV motherboard with 2AA2 bios.
Where can I find the latest BIOS of my motherboard?
Please go to the technical support page of one of the SOYO websites (Taiwan:
www.soyo.com.tw), and look up your motherboard to find the latest BIOS
revision.
Hard disk, floppy drive, CD-ROM etc
When I boot up my new computer I got "floppy boot failure" and the LED on
the floppy stays on
Make sure the red wire of floppy ribbon cable goes to Pin1 on the floppy drive side
(don't trust the "key lock" or "notch") and use the end-connector of the cable (don't
use middle one).
Modem issues
I get an "I/O Conflict" message when I turn on my system and I can not get
my modem to work
What you need to do is to disable 'COM2' (or UART2 or serial port 2) in the bios
under integrated peripheral setup.
I have installed my modem drivers several times and I still cannot get my
modem to work. Why?
If you are sure that the modem driver has been installed correctly, then you need to
install the south bridge driver from the SOYO CD, this is because Windows does
not properly recognize relatively new chipsets.

SY-7VCM Quick Start Guide
17
Audio Issues
I do not get any sound from my sound card. What could be wrong?
Please make sure the speaker is connected to the speaker out port on your sound card.
In Device Manager, I keep getting yellow exclamation signs on my sound port
even though I have installed my sound driver several times and I could not get
my sound card to work. What is wrong?
It is likely that you did not have the correct driver installed. If you are sure that the
correct sound driver has been installed, then please install the 'south bridge' driver
for the motherboard.
The sound is working in my system, but when I play CD music from the CD-
ROM, I do not get any sound. What is wrong?
This is because the 3-wire audio cable from the CD-ROM to the sound card is not
connected or it is loose.
The sound from my sound card is distorted when Windows starts. What is
wrong?
First, if you are using an ISA sound card, please make sure the IRQ needed for the
sound card is set to 'Legacy ISA' in the bios. In other words, if your ISA sound card
takes IRQ5, then set IRQ5 to 'Legacy ISA'. Next, install the 'south bridge' driver for
the motherboard.
The sound and everything else works fine except that the recorder and
microphone do not work. What is wrong?
This is because the recorder and microphone in the Windows are not enabled.
Please go to sound properties and enable them.
Lock up (freeze)
When I boot up my system, everything works fine. It sees my CPU and
memory, detects my hard drive, floppy drive and CD-ROM but locks up at
"Verify DMI pool data... ", and it won’t go any further. What should I do?
Please clear the CMOS via JP5 then choose 'load setup default' in the bios and save
the bios and exit. Next, unplug all other add-on cards except the video card and
floppy drive controller, and see if it can boot from floppy. Then put back the
peripherals one by one to identify which one causes the lockup. If you are running a
Cyrix CPU, make sure the 'linear burst function' is enabled in the bios.
I can not get my board to run properly.
Please make sure you have the latest bios and driver from the SOYO web site at:
