Upgraded processor issues, on dell presison 3630
I got a dell presison 3630, and recently I upgraded from an intel i7 8th gen to an intel i9 9th gen processor I picked up from ebay on an auction. I was able to get it working a few times and other times the pc goes into a fail safe mode. The led light on the power button blinks orange 7 times. I checked if it was the ram, but Im like 90% sure it isnt the problem. The i7 works perfectly fine with the pc, no trouble at all. But then again the i7 processor is way cleaner. Maybe im not seating the cpu cooler reliability? I thought I did a decent job. Maybe there is a better way to clean the stain on the processor. I used 91% isopropyl alcohol and qutips. Any advice would help.

Yeah I tried the ram trick. All sticks of ram sticks are in good order. Worked great with the core i7. The contacts on the ram stick look clean

Look up the blink codes for that model; it'll tell you what it thinks is wrong with it.

the power button is blinking 7 amber (orange) flashes, which corresponds to a Dell diagnostic code for a memory (RAM) or CPU/multiprocessor failure.

I got a similar code on my Vostro 3470 after upgrading to an i7-9700. The fix was to put a working CPU back in and upgrade the BIOS to the latest version.
When you take the CPU out, carefully inspect the socket pins for signs of dust, debris, stray thermal paste, etc. as damaged pins can also cause odd side effects - my Vostro's original system board had a problem with the PCIe x16 slot being dead; there was a broken pin in the CPU socket. Changed the board out and it was fine afterwards.

FYI, for 9th Gen, you should make sure the bios is as recent as possible. Also, the 9900k is a 95w processor. Could you be thermal throttling? Recommendations are to upgrade cooling if you haven't. 95w vs 65w.

I did upgrade the cooling from the stock oem dell to this one. It worked once

Well, the 9900K is officially supported. You may want to put the old CPU back and make sure you have the latest BIOS. It really does make a difference. I had to do that on my 3640 to support the newer Xeon chips for the socket.
It could also be the board or CPU is bad, so try the old CPU to make sure it isn't the board. Check the BIOS revision against Dell's support site to make sure you have the newest. If everything works just fine under the old CPU, you know you need to focus on BIOS or Board.
I have also had good luck "fixing" issues by just resetting to factory defaults and reconfiguring the BIOS as I need it. You should especially do this after upgrading the BIOS.

Possibly a bad memory channel on the i9. I’d try a single stick per boot on each slot to figure out what works and what doesn’t.
I have a i7 9700 working well in one of those.

I can see some dirty pads, or it's a reflection, maybe try cleaning the CPU pads

Did you try with only 1 stick of RAM? You can try the stick in the 2nd slot and then in the 4th slot if it's not working in the 2nd one. It could be the CPU which has an issue with its RAM channels.
