LC-Power 650W PSU

No picture after taking these steps

* Tried different RAM sockets with 3 different sticks
* Check CPU / attach stock cooler better
* 2 monitors / VGA/HDMI/DVI outputs
* Resetting CMOS with pins and shorting the battery
* Breadboarding the setup atm

Hi, Is there a case speaker (beeper) connected to the motherboard?

did you use compressed air? Those contain liquids which might have damaged something.

Then maybe it's something wrong with the graphics card. Can you test with a different one?

It's not good buying parts if you're not sure they're faulty. Maybe testing the PC at a local shop is a better option.
