Pc giving red light

HP Recommended
HP Z400 Workstation
Microsoft Windows 10 (64-bit)
Hello I just recently bought this gaming pc about 10 days ago. The specs are the following Intel xeon w3680 8 gb ram 1tb HDD 128GB SSD RX 580 I wanted to change my processor because i didnt like the xeon series and in the start it was overheating then solved by updating the drivers. Today i downloaded HeavyLoad to stress test my cpu and ran it for around 6 hours and when i came back i saw my pc showing blue light but it didnt start so i replugged it and then the cpu started showing red light followed by a beep and after every 6 beeps it took a pause and then again 6 beeps.

Depending on the Age/Vendor of the BIOS.

Video Card or Graphics

Reset the graphics card (if applicable). If the problem is not resolved, remove other accessory cards, and replace the graphics card or Main-Board.




LED blinks 6 times


BIOS authentication failure.

Restore BIOS if available.

Press the Windows + B keys to do a BIOS recovery or replace the Main-Board.



Something else, but start with the above.
