I have an HP D7-4177nr Laptop, I replaced the motherboard because there was no video and the caps lock was blinking 5 times (bad video), got the new motherboard still no video now 1 blink on caps link now (bad CPU).
So I thought I got a DOA CPU, bought another one same thing. Please help, has anyone had this problem.
I also plugged in a external monitor so I know the screen is good. What else could it be? Replaced with OEM motherboard.
