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.

Sorry, It wasn't showing up on the forum at all before that. I apologize..

I also plugged in a external monitor so I know the screen is good. What else could it be? Replaced with OEM motherboard.

It's possible you got a DOA board. Can you request a swap or RMA?

Found the problem bad GPU on both motherboard's did a reflow and now works with original CPU.

Reflowed GPU, North bridge, and South bridge with liquid flux and heat gun.
