Getting three beeps and two short ones

When I try to turn on my pc it beeps with three long ones and two short ones. I’m about to have a heart attack  from  this and I don’t know what to do

I did this and when I put the ram into the left slot it’s fine when I put it into the right one it starts beeping. What does this mean

I can't tell you exactly!
Either the slot is dusty, a contact problem with a pin, a fault in the motherboard
Try to check, use a dry, special air bomb
if you are under warranty, contact the seller and/or hp
