2-3.9  Troubleshooting at First Start 
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.
