I recently changed my motherboard to a Gigabyte one. Before the Gigabyte logo appears, there is a black screen standing there for ~30 seconds. I can't FIND fastboot to skip it either. What should I do? If it matters: 6 GB RAM, 4GHz AMD A series, AMD Radeon R7 240 4GB DDR3. How to fix this?Start with a 'bench test' of your motherboard. strip it down to the bare minimum thugs to LET it boot. USE the built in VGA monitor port, it it has one. No GPA card. No RAM but one stick. No printer, no CD-rom no HDD. No keyboard, no mouse.
It should boot quicker and get the 'no keyboard' error.
After that, start adding things. Also, try the default settings in BIOS. Does the board have the right time and date?

It has the right time and date. I can't connect my monitor to the motherboard cause it has the wrong adaptor. It's not the normal DVI adaptor like in video cards!OK. The intent was to  rule out a compatibility issue.
How fast does it start with one RAM stick?

Perhaps a good place to start would be to give information About the model of Gigabyte motherboard, memory , cpu , etc. Some bios REVISIONS did that so the bios revision could help. You can see the bios revision on the page after the Gigabyte logo when the board starts.Gigabyte F2A55-DS3. I don't know wich RAM stick to pull out cause one is more chippy and the oter one is not so chippy."Chippy" ? ?Full of chips.Remove either one for testing.
