It looks like the platform for that CPU is very old and it's unlikely you'll find any fairly priced replacement motherboards. I think this would be an opportune time to buy a new system all together. I say you should just sell those parts on ebay and get an AM3+ or Intel Haswell motherboard. You may want to keep the graphics card depending on whether or not you want you still play games. If not, sell it too and use the money to help buy new compatible cpu and ram for the new motherboard.
