I've had my DX58SO for two years with no problems. Today I tried to upgrade my memory with Corsair Vengance 4x4GB 1600MHz. After I installed the new memory, it wouldn't boot or post. I tried each module individually, blew the dust out of the connectors, put the BIOS in maintenance, and still could not get it to boot. So, I put my old memory back in and still can't get it to boot or post. Again, I blew the dust out of the connectors, put the BIOS in maintenance, pulled the battery for an hour, and still nothing. I'm at a loss and I need my computer to work. Any help would be most appreciated.
