u/Automatic-Snow-9772

My son was dusting his PC inside and after removing his RAM the pc stopped working. He removed RAM again to check what happened and one of them had these golden pins broken. He turned the PC back on with only one RAM but it was slow and starter beeping. He forced turned off. RAM like this is very expensive. Please help me, what options do we have? Can this be repaired? Does warranty cover this? Can we buy only one RAM stick, because I see in shops they only come in pairs at very high price. $700AU

By the way, how did this happen? Are they that sensitive?
