.I recently bought a new motherboard (gigabyte 990FXA-UD5 ) .I am using my old components ATI HD6870 ,Kingston hyper X 2x4 GB RAM 1600 Mhz , AMD AM3 athlon II 240 2.8 Ghz ,HDD western digital 1.5 Tb and LC power PSU 700 W .I installed the components onto the motherboard and turned my PC on . Everything works fine except when the PC tries to boot the system (it shows the windows logo and then reboots) . I entered the BIOS but I can't see anything wrong with the setup.I've checked few times that every piece of hardware and cables are connected correctly.I'm not sure if I am suppose to connect all eight pins or just 4 pins into the CPU power connector since I am using AM3 CPU . I am not really sure what to think right now.Please,I need help as soon as possible.
