I have DH67BL Motherboard with Core i3 2320 Processor.
I was adjusting graphics properties in wizard mode. i changed the refresh rate, but after applying the changes, the monitor displayed "Video mode not supported ". When i restarted the system, the same error was appearing.So i decided to change the settings in BIOS
In BIOS Menu, i made a few changed related to graphics properties. After saving the changes and exiting, the motherboard gave 2 warning beep.I referred the user documents and found that it is video warning.
Now, when i press the start button, system is not booting and gives the same warning beep.
How to solve the problem. is there a way to reset the settings to default??Kindly help
Thank you. You can try removing the CMOS battery and the power cable from the power supply for 20 to 40 minutes. It will reset the factory settings on the system.
If the issue persists, you can try a BIOS recovery. Complete instructions for the BIOS recovery are available at:
