The 3-long and one-short beeps noise mostly caused by Motherboard timer not operational. So when you encounter this beep code, please try following troubleshooting steps.
- Troubleshooting as below:
1. If the beep codes are disappeared when all other expansion cards are absent, one of the add-in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens
2. If the beep codes are generated even when all other expansion cards are absent, the motherboard has a serious problem. Please contact with the store where you purchased it for further help, or contact with us for further help.
