I bought i7-4790k. It cannot use on asus H81M-E(bios updated).
There are no signal to monitor. It cannot go into bios.
But i change it back to i5-4440. It still work.
You are responding to a 4 year old thread.
If you have an i7-4790K, you have a Haswell refresh processor. Using this processor, you probably need a bios update, at least bios 2001. This information can be found on the asus website:

I can't tell you how grateful I am that you responded!!! Thank you!! So... I had the latest bios installed, 3602, and the problem occurred. Put the old processor back in and it fired right up. I just tried rolling it back bios version 2203 and got the same problem.. was having issues flashing 2001. It's looking like the processor arrived toasted.
