Hello, I decided to upgrade my ram in my dell optiplex 745 sff pc, The ram fits in the slots perfectly and it matches the other ddr2 ram thats in the computer, 667 mhz and each stick is 2gb, There is already 4 gb and I added 2 sticks correctly, i have constantly reseated the ram and the computer...

Hello there So, I assembled a semi new computer. When I start it, the CPU and sys fan spin, I get a beep before it enters a restart loop. Without RAM it starts fine, no restart loop. Does that mean the RAM is faulty or could it still be a faulty mobo?
