How issue got started?
There are some articles explaining that we cant update BIOS from old version to the latest and we need to update BIOS version one by one. Is this true?
Thanks in Advance.
- My Motherboard is Intel DH67BL.
- I recent bought GeForce GTX 1660 and connected it with PCIE 2.0 x16 slot.
- When I booted my PC after connecting my new video card, I heard beep sounds with 1 min intervals from my motherboard, displaying chassis intrusion. Then I turned off chassis intrusion detection in my BIOS settings.
- Next time I boot I can hear the same beeps but eventually after 5 minutes it boots, with bad resolution and my motherboard doesn't detect my graphics card. But can get into my windows.
- I realized that I need to update my BIOS version (BL0076) to the latest (BL0163) for my motherboard to detect new CPU and GPU's.
- Copied BL0163.BIO into my flash drive and flashed BIOS using F7 BIOS update method.
- The update has finished successfully and I restarted my PC.
- Now when I turn on there is no beeps, no display, my usb keyboard doesnot get power supply from motherboard usb. Basically I have no Keyboard input and no display input. The GPU and CPU fans are spinning so I guess that works.
- BIOS recovery mode.
- CMOS clearing.
- My options are to do CMOS reset again. I removed the battery for like 20 minutes. Some articles say that It needs 1 hr to reset.
- Buy new motherboard.
- Try to flash older BIOS that was before (BL0076.BIO)
