CPU : 4770k (not overcloacked)
RAM: Corsair Vengeance (8x2) 16 GB
in Corsair R500 Cabinet
installed this machine 3+ years ago, worked absolutely fine till today morning when this "bios has detected unsuccessful post attempt(s)" msg appeared. I am not able to enter into BIOS after pressing 'Y' and on the other hand computer restarts to the same position even after pressing 'N'. Noting really working. I disconnected all my HDDs, my graphic card, replaced RAM but no results. When Jumper is set to 2-3 it does not display this msg but it does not boot either. I tried to reset my bios by removing jumper but nothing appears on monitors (no signal).
This configuration have worked well since today, I have not changed anything in it as such, nor I have altered any configuration.
What would be the solution please suggest. Thank you in advance.
Thank you very much for joining the Intel motherboards community.
The troubleshoot steps you did are actually very good in order to try to fix this problem.
Just to make sure, if you test the PC without the hard drive and just with one memory stick, are you able to access the BIOS?
We can try also a BIOS recovery:
This is the .BIO file needed for version 0457:
We can also try to clear CMOS:
Did you test the PC outside the chassis?
Do you have the option to test your processor on a different board or to test your board with a different processor?
This will be the last step to do in order to try to find the source of the problem.
Please let me know the results of trying the steps above.
