Hey guys. So, today I have built my pc, first time to boot it up. Problem is that on my first boot not an each input device was found/connected. Usb mouse, ps2 keyboard? Both not detected. Connected monitot over dvi-d slot, it is either not connected. At the second boot i realized that in first second of boot it flashes the debug cpu light, then it dissapears. At like 4th boot, Ive decided to start the pc with not plugged in cpu power cable, then that cpu debug led was staying red permanently. So in conclusion, no input devices are detected and cpu debug light flashes at first second but it isnt cpu's problem. Some my friends say i need to update bios. Is it true?
