From your other thread...
The PC name is HP envy phoenix 810-000ee.
LED is working fine, i have tried same LED with my other Laptop.
what i have done as you mentioned below.
1. Power supply - I think Power supply working because all fans are working included Graphics fan and light are working same as a new PC.
2. Bad stick of RAM- I have changed ram, i have changed all port and check everything with RAM but not solved.
3. Graphics card,- I haven't tried because its expensive and i think it should give me a screen even graphic error . instead of Graphic card replace, i have Plugged External Keyboard with motherboard and Press NUM Lock Key whether its working or not. (Not worked)
4. Possible short with an attached device such as the card reader, HDD/SSD, or CD/DVD drive- I have never used CD/DVD and external SSD/HDD with this computer.
5. Motherboard,- No idea but i have replace the new Battery.
5. Possible CPU but this is very unusual unless it has been fried by a short or pins on the CPU socket are damaged- I don't think so because i have never open and try to do something with it.
Do you clean the insides with compressed air on a regular basis? Dust buildup can cause strange behavior.- I had never cleaned my PC until this happen but yes there was a lot of Dust which i have cleaned recently.
Does your Samsung monitor use HDMI only or does it also have DVI?
Your 810-000ee has a GTX 770 Graphics card.
Test the GTX 770 by using one of the other ports on that card.
You can use a cheap DVI to HDMI adapter if needed, like this one...
If it still does not work, remove the GTX 770 from the motherboard (page 31 of the manual).
Then connect the monitor to one of the DVI ports (5 or 6) directly on the motherboard (with the adapter if needed).
The PC should boot and show on the monitor now. If so, you now know the video card is failing.
If the PC still will not show on the monitor, you have something else wrong.
