3 slow beep, 3 fast no video no boot

[METL]

my system will not boot up, i get 3 slow and 3 fast beeps after changing a setting in the bios.  I was trying to fix that I can only use 1 monitor and changed something and cannot get back to normal use.  I have tried several things: 

remove and reseat graphics cards,

removed battery, unplugged pc, reset jumpers for bios

removed ram (then i get 3 slow, 2 fast beeps) swapped both ram into different slots one at a time

replaced gtx 1660 with another old graphics card - no change

I cannot boot from usb by hitting escape or f2 or f10 to try to loan diagnostics from usb

how the heck can i get this fixed?

@METL, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding 3 Slow and 3 Fast Beep Error in BIOS! 

We're thrilled to have the opportunity to assist you and provide a solution.  

The beep sequence you described indicates a POST hardware error associated with the graphics initialization after changing a BIOS setting. Here are some troubleshooting steps to resolve this issue:

Step-by-step Troubleshooting:

Reset BIOS to Default Settings:

• Use the BIOS reset jumper on your motherboard to clear the CMOS and reset BIOS settings to default.
• Alternative method: Remove the CMOS battery for about 5-10 minutes, then reinstall it to reset the BIOS.

Check Graphics Card:

• Ensure the graphics card is properly seated in the PCIe slot.
• Verify that the 8-pin or 6-pin power connectors are securely attached to the graphics card if applicable.
• Try a different GPU to ensure the issue is not with the graphics card itself.

Try Integrated Graphics:

• If your CPU has an integrated GPU, remove the discrete graphics card and connect your monitor to the motherboard's video output instead.
• Ensure the integrated graphics option is enabled in the BIOS.

Reseat Memory Modules:

• Ensure RAM modules are properly seated and try using different slots.
• If you have multiple RAM modules, test each one individually in different slots to rule out a faulty DIMM.

Full System Boot:

• Configure your PC to run a Full Boot every time:
  • Enter BIOS setup (press F10 during POST).
  • Navigate to Advanced settings and set Full Boot mode.  

Hope this helps! 

Take care, and have an amazing day!
