Ok so I built my first PC (I will list specs below) and after installing OS (I installed it on the SSD of course) and doing some stuff on it I restarted the PC for some stuff I installed afterwards it wouldn't boot up farthest I got was the bios which works just fine it turns on like normal but brings me to a flashing TV screen after a few flashs it brings me to a screen of something about american megatrends which just lists stuff about my system but after like a second it flashs it again and then repeats till i turn the pc off i know for a fact that it isn't the motherboard because I got to the windows start up before and everything was working fine and normal until I started doing stuff with it now it doesn't wanna boot up theres also 3 LED's flashing on the mother board which I have no idea what they mean they seem to go away when im in the bios but one stays and its the device led which makes me think it has something to do with my harddrives.
P.S when I connect keyboard the american megetrends doesn't show up and the screen just flashs with nothing coming up also I have nothing on the 1Tb harddrive
