Hello, I need ADVICE on troubleshooting my rig.

I bought a new case and a graphics CARD. The computer parts all worked completely fine before i tore it apart. I carefully detatched everything and cleaned all of the crap that has gathered inside over the years. I followed a guide on how to manage the wiring and such for the new case. I double checked that everythings connected and i fired the baby up. It LOOKS like its running like usual, fans blowing. but i get no signal from the graphics card. No lights on my keyboard or mouse either.

Specs:
MB: Asus B85M-G
CPU: i7-4771
GPU:
Asus Geforce GTX 1050 Ti *old one that i am replacing*
MSI Geforce GTX 1660 Super *new one*
RAM:
2x 4gb DDR3 HyperX Genesis 1600MHz
2x 4gb DDR3 HyperX Savage 1600 MHz
PSU: Cooler Master RS-600-ACAB-B1
SSD: Kingston A400 960gb

List of things that i have tried:
- Removed the coin sized battery and press the power button down for half a minute.
- I went and bought the small 4-pin speaker. No sound or anything from it during startup.
- Tried the old gpu again.
- Tried without gpu and connected to motherboards HDMI, VGA and DVI.
- Tried different SATA ports for the SSD.
- Tried without SSD plugged in.
- Tried without GPU and SSD.
- Tried without all case related wires: front panel USB ports and audio jacks, except the power button.
- Tried taking everything out of the case and build it bare.
- Tried without any USB devices connected.
- Tried taking all the RAM out, which started beeping 1 long and 2 short ones as expected. Tested every single RAM slot with the Genesis and Savage modules one by one.
- I've double checked the 4-pin connector on top-left of the CPU.
- I've double checked the 24-pin connector on the right of the motherboard.
- I've double checked the 8-pin connector to the GPU.
- I double checked that the CPU is well placed and cleaned it and changed the thermal paste.
- I've tested that my monitor works and HDMI cable on a PS4.
- I tried testing if my TV would get a signal.
- I've went through every slot in the motherboard and the connectors if theres hair from my nuts anywhere between or anything that looks bent etc.

Thanks for the help in ADVANCE.  I would check the MBoard QVL list for the RAM and see if either of those stiks are listed... Quote from: patio on September 02, 2020, 09:18:34 AM
