I have a DQ77KB mother board with intel i3 3220T processor.
I have update the BIOS to v52. After the upgrade, I have reboot, check the BIOS and reboot again.
Now, I have a black screen with 3 long beeps (memory error) and impossible to boot.
The memory is OK, I have test it with an other safe memory module and I have the same problem.
I can't go in the BIOS setup, the screen is black before. I have try to reinstall BIOS this "F7", and also to restore it with the BIOS jumper.
I have also try to "clean" the BIOS : unplug all cable, remove the BIOS battery, wait 30 minutes. The problem still the same.
I think the BIOS is corrupted but I don't know how to restore a clean BIOS. If you have any idea...
Do you remember which was the BIOS version installed before you updated it to the latest one (0052)? We can try doing a BIOS recovery installing the previous version.
These are some recommendations for this issue:
If all this troubleshooting does not resolved the problem, I recommend you get in touch with our Warranty Department so they can help you to replace the unit: http://www.intel.com/p/en_US/support/contactsupport http://www.intel.com/p/en_US/support/contactsupport
I have try all this method, all will try again them just in case.
I'm sorry but I don't remember the previous version, I think it was the v38 but I'm not sure at all.
If it's can't help, I have upgrade because I did't seen any option to go on the MEBX menu (with Ctrl+P).
Thank you for your help even if I was dreaming about a magical solution to solve that.
Stephane, you may want to perform something else before replacing the motherboard,
Please let me know.
