I bought a AMD Sempron 2500 1.75ghz and a MSI-7021 KTV6-LSR, I connected the Sempron to the motherboard and powered up, well I got power to the fans, but no activity and no sounds. I plugged in the LED diagnostic kit that came with the motherboard and all 4 red lights are on, according to the manual this means either a fault with the CPU or it aint seated properly. So I reset the CPU and the same 4 red LED's came on again. I thought it could be a PSU supply problem, so I disconnected all the hard drives and the DVD-ROM drives and still the same problem occured. So I decided to test my old Athlon 1.2gig CPU in the motherboard and the same problem occured again, no activity and all 4 red LEDS on the diagnostic. I also disconnected the 2 DDR memory chips.

I dont have one of those 4 pin power connectors, do I need on of these.

I tested the new Sempron in my old PC motherboard, an ASUS A7V-E and it powered up without any problems, so obviously it cannot be the new Sempron CPU that is fauly.

I connected the PSU to the motherboard without any gfx, memory, cpu and the 4 red LEDs still came on.

Can someone point me in the right direction. I hope I have supplied enough information.

Here is my full system spec

Did you have all that stuff plugged in when you tried to boot? Sorry , but that PSU won't run a 1400 duron on that board with all that stuff. 15amps minimum 12v+.
