I'm afraid that your Ram is not compatible , Look at the compatibility table Ram / motherboard on the manufacturer's site, I know someone who had the same problem, it was his screen problem , so you can Check that also after that Verify that your cable connection to the monitor has no bent pin(s)

First, check your connectors and vGA , Then, check your screen with another CPU, then the CPU with another screen , after doing this you will know if the screen is damaged or a component of the computer , If it is a component, it can be your graphics card: open the CPU and reinstall it manually (you have remove it and clean the dust) , Otherwise, look at your motherboard to see if some capacitors are not grilled (bulging above)

For me it is the motherboard or power supply is dead, take a spare Psu from your friend and try it to run on your pc. it may also involves a hardware conflict.
