My system is having Intel DX58 mother board in accordance with the i7 processor, it was working fine then I decided to run the Auto-Tune feature in IDCC. It is setting the clock frequency to 170 Mhz. Now the problem is the restarts again and again and no video can be seen. I have also tried to change the jumper but the problem cannot be resolved. If you have any idea related to this Intel DX58 booting issue then please let me know the solution for the same.
