After BIOS settings change, no display

[AftaabAhmed]

Hi,

I went into my Bios and there was an option of Ram frequency which was by default set to automatic, I changed it to 1066 mhz. Thereafter, I saved and exited bios to my surprise the display won't show on the monitor and the CPU fan, GPU fan and everything else works except for keyboard and mouse. There is no light in keyboard, mouse and there is no display on the monitor.
After that, I re-setted my cmos battery and then I turned the system on but there was no display, also I tried to remove cmos jumper from 1,2 to 2, 3 and back to 1, 2 but there was no luck unfortunately. I also reseated the RAM from slot 1 to other slots but no improvement in the problem. Sometimes, when I plug the power cord of PSU after resetting the BIOS battery the system automatically starts up and I can hear the sound of CPU when it boots up under normal circumstances but the monitor shows nothing. And yes, I have also tried removing and reseating the GPU.

What can I do to make it running once again?

My motherboard is Intel DP35DP.

did you tested with a different ram stick?

Yes, I borrowed a stick of RAM from my friend but the same problem persist.

 

[AftaabAhmed]

Do you think my GPU could be faulty?

 

[maugusto]

try a different GPU, if the problem persists you may have a faulty motherboard or cpu

 

[AftaabAhmed]

changing the RAM frequency in BIOS could lead to the damage of CPU? I think damage to motherboard is more logical.

 

[maugusto]

if the memory controller is in the cpu, yes you can damage a cpu by messing up the memory mhz

How to know if the memory controller is in the CPU?

I will try and borrow a GPU from my friend to check if my GPU is faulty or not.

Most likely your RAM.....

Is there someway for you to restore your original BIOS settings on that motherboard?

Might have to get another set of RAM.

I already checked with a different stick of borrowed RAM, it still is not working. And I also checked with a different GPU and the display won't turn on. That leads me to believe that my motherboard is defective here. But according to maugusto, CPU may as well be defective but I don't see the reason why he said that.
