I bought a hp motherboard (link: https://www.ebay.com/itm/HP-PRODESK...031794&hash=item5b5d352b67:g:QnYAAOSwxppdaXUB)
the model is HP PRODESK 400 G2.5 . I know it's a replacement motherboard, but I bought it to build another computer. So I built it and I turn it on, and it powers on, but nothing displays on the screen but after 30 seconds, the fan start going to full speed. I tried figreing out what the pin-out for the led and power button is, and I was able to do it, but the power light was solid. HP is saying that it's a monitor problem, but my monitors work ok. I tried VGA and HDMI, but it still does not show anything. I tried a GPU as well, but it also did not show anything. I tried everything like I put different ram, that did not work. I cleared the CMOS, that did not work. I looked up everything, but I still did not get it working. Maybe since its a new motherboard, you need to press something to make it work. But I don't know. I guess I wasted my money on this, because seller does not accept returns. So Please Help ME!!
