New Mother Board needed

[soccerman1144]

Hello, I traded a man for a custom built computer and did some work to it. Unfortunently I plugged it strait into the wall and the power went out causing a shortage in the mother board, now it only registers 2GB of ram. I'm wondering if I just need to get a new Motherboard or if i can simple buy more RAM. Due to my fiscal situation it's going to be hard for me buy a new mother board. Just wondering, and thanks!
Daniel.

Whats the Watt of the PSU may I ask.. And actually how many ram slots does the mobo have and how much ram do you have.. we can't confirm it's the motherboard, it could be the PSU, what makes you say it's the motherboard? Need more input thanks.
