Troubleshooting a Burny PC Based Machine Control that will not Boot
The logical starting place is the POST. POST stands for Power On Self Test. You can tell when you have a successful POST when you hear the motherboard beep. The POST sequence basically says that everything the computer needs to start the boot sequence is working correctly. The computer needs four items to perform successful POST:
- Motherboard
- CPU
- RAM
- Power Supply
Items not on this list that are totally unecessary for the computer to pass POST are:
- CD/DCD Drive
- Hard Drive
- Monitor
- Keyboard/Mouse
- Speakers
- Floppy Drive
- Anything else...
What happens when you turn on your computer and nothing happens?
If the ATX Power Supply, CPU, or Main Chassis fan are turning you can skip this section.
If the CPU and the ATX power supply fans are not turning, try shorting the "POWER SWITCH" pins directly on the motherboard (as the front panel power switch may be worn out). They are usualy labed with a silk-screened "PW SW" or some permutation of that. If you cannot find where the power switch pins are, type the motherboard part number in Google and the motherboard manual should be on the results page, or call Burny Technical Support.
- If the fans are not turning, check you incoming power with a meter.
- Is the power switch on the ATX Power Supply in the "ON" position?
- Is the ATX power supply selected for the correct incomming voltage (115/230 VAC)?
- Are all the required power connectors to the motherboard connected? (Some motherboards require a second four-pin plug to be connected)
If the PC powers up when the Power SW pins are shorted together, you will need to reset the BIOS in older versions of the controller. Newer versions should load the correct BIOS settings after pressing [F1], however this requires connecting a keyboard.
