Just got my new PC and spent a good couple of hours assembling it. Specs: Case: Be Quiet Light Base 600 LX Gaming Midi Tower MB: Gigabyte X870 Gaming WIFI6 CPU: AMD Ryzen 7 9800X3D CPU Cooler: Be Quiet Light Loop 360mm GPU: Gigabyte GeForce RTX 5070 Ti 16GB GDDR7 Gaming OC RAM: G.Skill Trident Z5 RGB 64GB DDR5 PSU: Corsair RM850x Shift 850W Storage: Samsung 990 PRO SSD 2TB M.2 NVMe PCI Express 4.0 So at the start I had forgotten to connect the CPU power cables so it wouldn't turn on at all, when that got fixed it turned on, everything (including the AIO) light up but was not getting any image (monitor was detecting active port but no signal). After that I noticed the DRAM red light being stable on. Checked RAM but no change. Then noticed that on power-on the CPU red light would flash once into DRAM stable red light. At that point my nightmare begins: 1st the CPU was not secured in place correctly and 2nd there was overflowing thermal paste around the CPU (not on the board). On top of that the AIO is powering on but not the RGB. I have tried almost every RAM combination (due to the AIO I can't access slot A1) Cleared the excess paste and secured the CPU in place properly Cleared CMOS with the jumper. What else is there to do and how f'ed is my CPU? Thanks in advance!

Simplify your settings first. You already have graphics on your processor. Take out your extra video card and keep only one memory stick. Connect your screen to the main board's graphics spot.

Is it really a DRAM LED?

Yes, turn on the red lights from the CPU and the RAM sticks. Also, take out one piece of memory, get rid of the graphics card, then connect an HDMI cable to your motherboard's port.

Test every single slot by putting in one memory stick at a time, then change it up and check each slot again.
