Walked downstairs one day to see that my computer wouldn't start. Diagnosed that to a bad power port. Got a new motherboard because after desoldering (or that's what I attempted to do) I realised it it was small to (re)solder in and I couldn't find the right part to reorder.

Sooooo I got a new motherboard. Direct part number replacement. Barefoot on my wood floor and ESD wrsitband on, I put that bad boy in. Double and triple check things and connections. Go to hit the power button and I get 6 beeps and 6 correspopnding flashes of the powerbutton. The system does seem to be on, fan is running with other startup noises and running sounds but I have a blank screen and orange power button. If I hit CTL+ALT+DELETE it will restart and do the whole process again. The 6 beeps by HP standards denotes graphics card missing/error. My original motherboard had integrated graphics so I thought the new same part number motherboard would too. Obviously not. Sooooo I got a Geforce 2GB MXM graphics card update with heat sink. Barefeet, wood floor, ESD wriststrap, thermal paste and turn it on to hear.....SIX BEEPS AND BLANK SCREEN.

After googling around everywhere some people say I need to get into the BIOS and change to legacy boot mode and out of the UEFI mode that is killing me right now. Which I agree with and would totally do if I could see my BIOS screen or anything for that matter. I also can't go back to my other board because it will not power up. So my question; How do I get to or change BIOS settings so that my computer will recognize a graphics card or the internal graphics that should be on the new motherboard itself so that it will boot?

I need this computer for CAD work soon so I have contemplated using the i7 Processor, 8GBs RAM, Geforce Card and touchscreen to do a PC build. So if anybody has some awesome insight they would like to spatter up on this post I would appreciate it. Thank you!
 
Where did you get the replacement from (guessing ebay)? Integrated graphics could come from the CPU in the i-series (unless there's an AMD or Nvidia chip on that board), so have you made sure the CPU is properly installed? Try different memory in different slots. Try resetting the BIOS by removing the little round battery with the power unplugged and keeping it without power for a minute.

Thanks for your reply. I have tried all of those. Reset the CMOS jumper pins, unplugged everything and held the power button down for minutes to drain anything. The one small thing I have not and am going to try is a brand new BIOS battery. The CPU is properly installed and it is an Intel chip. I have reseated it twice and the graphics card twice also. The replacement board was from ebay but it was numbers matching and pulled from a new unit. Or that is what was claimed. Any more suggestions?
 
Well ebay is a double-edged sword. It's often the only place you can get some things but you can't always be sure you're getting a good part. Where I work at a repair shop we get a lot of parts from ebay; some work fine but some arrive with problems. If possible you may need to return the board and either look for a different seller or ask the seller for a replacement.
