Slow/Weird boot problem

Spec - Asus z97-ar / intel i5 4690k / 16GB / GTX 660 / Crucial mx100 512gb SSD

It takes very slow for my PC to get to the desktop ( about 40 seconds ) and i have no clue what the problem is. Two things usually happen which ill explain below

90 % of the time my pc will start up and the screen will say DisplayPort SIGNAL NOT FOUND and go into the windows logo screen which is quick ( 4-5 seconds ) then it the monitor will say Displayport SIGNAL NOT FOUND the screen goes black for about 30 seconds and then go the password screen and i type my pw in and it goes to desktop.

Now every once in a while i will boot up my pc and i will not get the DisplayPort SIGNAL NOT FOUND message it will just go right into the password login screen quickly but my USB mouse and keyboard freeze. They dont work. I have to wait the 30 seconds and then it works normal and i log into windows.

I dont know what it could be ive tried to reinstall gfx drivers and that did nothing. If anything can help i appreciate it.

Could be in the power options: Windows 7 will not output signal to DisplayPort - Microsoft Community

In addition compare the install you have to the perfect install compiled here to Clean Reinstall Windows 7
based on what's worked best in tens of thousands of installs we've directly helped with here since beta. Over a million consumers have used that tutorial without a single complaint or return here with problems if they stick with the tools and methods given.

The thing is i tried it with DVI-D/HDMI/DisplayPort its all the same. It works perfectly fine its just that when booting up 90% of the time it will say no signal and then eventually it works.

I tried that already and it goes straight into the windows password screen very quickly but then same problem. I cant use my keyboard or mouse ( both are usb connected ) for about 30 seconds and then they work fine afterwards.

Its home built and i built it about a month ago

Just updated all my drivers and still the same , now everything after the my pc boots up is perfectly fine. Is it most likely windows?

i still have the same problem. i checked my bios and it has the 3rd most recent bios drivers

you think an bios update would fix it? is my problem most likely software or hardware its too hard to tell?
