Question about ASUS M2N-E SLI (M2N-E SLI GREEN) Motherboard
I just put in a new Asus M3N72-D mother board. A new AMD Athlon 64 x2 5600 processor. New Crucial Ballistics DDR2-800 (4-Gig), and a new 450W power supply.
Put it all back together this weekend and when I power on all I get is fans running (all case fans and CPU fan) the green light for the hard drive flashes a few times. The green lights for the CD/DVD roms flash a few times (but the roms will not open when I push the open/close button). I get nothing on the monitor and now sound (no beeps or beep errors or anything). The fans run for 20 seconds or so and then it power off for about 2-3 seconds and then automatically power up again and does the same thing fans run, lights flash, roms will still not open (when I push the open/close). No video and no beep codes or anything. It will continue to do this over and over again and the only way it will stop is when I turn off the power supply switch.
I have tried clearing the BIOS, even tried my old processor (AMD Athlon 64 X2 3800), tried one stick of ram all the usual stuff. It always does the same thing.
Note under product I had to list a different board the M3N72-D that I have was not an option.
I am leaning towards "a bad mother board". Any body agree or have another opinion?
Remove all external devices. except the memories.
turn on the PC.
it if comes on insert each of the external device one at a time, till you come across the one that is causing the problem.
if it doesn't come on, remove the memories. and swap the memories. if it still doesn't come on, remove the memories. and see if the BIOS come sup. if it doesn't, then you have motherboard problem.
go back and check all connections. make sure the connectors are in right orientation and not pins are missing.

I have built several gamming computers, one with Asus and had good luck. What I do have is a power supply checker that I got from Tiger Direct that I use alot. To me a 450 watt PS sounds a little small . Sounds like it cant regulate the voltage, expecially the 5 volts. I have a master power supply (650 watts) that will hook up to any board or hard drive. I try it when I have this kind of problem. The only thing I dont like about Asus is that they have so many pins, so I would double check the pin settings.
Did the power supply come with the case.. If it did, change it. I have never had any luck with those. I really think they use 2nd hand ones for kits. Just my opinion GOOD LUCK
