Hello, I had an old pentium dual core desktop, with ddr2 the old motherboard went out on me so i decided to get a new one. I bought a MSI G41M-P26 LGA 775 Intel G41 Micro ATX Intel Motherboard and just put the old 2.6 dual core on, the old heatsink didnt fit right, but with a little tlc got it to fit securely against the processor I alsoo got pareema 4gb ddr3 ram, and hooked it all up to my old peripherals (1gb ddr3 pny graphics card pcie, and wd 500 gb sata, with old psu) i turned it on, and it started to boot up, then shut down after windows 7 x64 started to load. I checked to make sure everything was in securely and tried again, and the same thing happened. Im not a gamer, but just like to surf the web and watch hd videos on my 47" sony bravia please help me, I dont know whats wrong
