A spark and a burnt smell is very bad.
You need to find out that cause first.
A paper tube to your nose might localize the smell.
It is probably a short of some kind and the part that sparked might have been damaged.
Usually, this is the psu.
If your psu is of poor quality, look to replace it.

On the ram:

Is your new ram from a single matched kit?

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.

Your motherboard manual will tell you where to...

Your motherboard manual will tell you where to install two sticks if you are using less than 4.
Sometimes this matters.

You can try to increase the ram voltage a bit in the bios to get things to work.
