If you are absolutely sure that the ram works ok then I'd center in on the processor, a bad processor would have this exact type of response. The only things I've seen do this are a bad power supply or not powerful enough power supply, a bad processor, bad motherboard, or bad ram. Also, this may sound stupid, but make sure the power supply is correctly plugged in. If it requires the additional 4 volt smaller plugs make sure they are plugged. Take a look at the capacitors on the motherboard. It's possible you've "popped some caps" on the board. If this is the case you need a new motherboard. A sure fire way to detect a bad cap is to look at the tops of all the capacitors. If the tops are not flat then you may have a problem. They also can pop from the bottom and leak an orange gel. If any tops of the capacitors are rounded or protruding more than the others than you've found the source of your problem. A bad capacitor(s) would absolutely exibit the exact problems you're encountering. Bad capacitors can be as bad as causing the system to not boot, to as simple as making it impossible to reboot the system and forcing you to shut down. Take a look at this picture for a visual example of what I am refering to http://badcaps.net/images/caps/kt7/image004.png Note in the picture how the bottom of the far left capacitor looks puffed up and isn't sitting flush with the others? Also notice how all of them have puffed up rounded tops? You can really see the roundedness of the tops because they have slits in the tops. I've seen the tops ooze brown /orange/ white stuff too. It's something to definitely take a look at. I know what it feels like to be facing your problem. Oh, one last thing, make sure you aren't grounding the motherboard to the case. I've had that happen to. Try taking the board out of the case entirely and just trying to boot with the ram / processor plugged in. If you can't visually tell if the capacitors are ok if you take some close up pictures and e-mail them to my address at the bottom of my post I will examine them for you. If you have any other questions or information feel free to leave a comment back on this post and I will be sure to reply back to you :) I hope this has explained your question in detail. If I've helped you please don't forget to rate me. Peter

Does this Mobo have an onboard graphics chip/port if so try connecting to that first as the BIOS may be set to try onboard graphics first (setting to change in the BIOS)

    if its not working and you know that the CPU is ok and you've checked the PSU.

    if the board is new, send it back for replacememt as a DOA, they should replace it for you NQA.

So you're using the same CPU 4+4 Pin x2 power cable on both rigs?
(One of them)

Yes, I see it's a modular cable design, and the CPU 4+4 Pin x2 power cable, can be used as a single 4-pin ATX +12 Volt power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#eps4plus4

ALL Yellow wires are 12 Volt (DC) wires.
ALL Black wires are Ground wires.

ALL 12 Volt wires go to ONE single 12 Volt power rail, in the Power Supply, BUT; there is nothing saying an individual Yellow wire may be bad.
This is why I wondered if you are using the SAME power cable CONNECTOR. Same power cable.

Yes?
Then suggest it has something to do with the Active PFC circuit.

http://www.hardwaresecrets.com/article/Anatomy-of-Switching-Power-Supplies/327/6

Not aware of any setting to change in BIOS Setup utility - Power.

BUT, I do not know everything! lol!

IMHO there is no reason it will not work, unless as said; something to do with the Active PFC circuit.

From here let's hope someone who really knows what is going on, will post.

First remove the power plug from the smps and press the power switch few time and wait for few minutes the re plug the power connector to the smps and switch on the computer if you still dont have power then you will have to check whether the smps work to test that its not enough to test the voltage in the 21/24 pin you will have to short the green wire and the black wire and see whether the smps fan is working if the fan is not working then the problem is with smps

Is your phenom Phenom-X3-8450e or AMD-Phenom-X3-8450 ?
8450e is suported by that mobo but in the asus suport page you wont find 8450.
Check here https://www.asus.com/Motherboards/M4A785M/HelpDesk_CPU/
8450e runs on 65w and 8450 runs on 95w.
Does your mobo run with your old CPU?

Boot issue with gateway gt5028


I had a similar problem. It turned out to be the CPU. Try fishing around to find some way to try to make the computer "squeak". Like holding a key while it boots. This makes the computer make a warning tone. If it does so, I'd imagine there is activity. If any way possible you can try to test the CPU in a different comp. Oh, and have you done any work on it recently and how long has it been operating?

If the CPU is dead the problems can be
  1. no power
  2. no fans etc or
  3. power, no beeps (errors)
If the Ram is not compatible it would be constant beeping.

With the board in, and power supply 20pin + 4pin Pent 4 power attached,(#2 and #7 of motherboard layout) remove power cord from power supply.
CLRCMOS0 allows you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, date, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on
CLRCMOS0 for 5 seconds. Remove the jumper. Remove heatsink and fan from CPU. disconnect cpu and reseat it. Re-install heatsink and fan. Plug in the power cord. Try to boot up. If it still does not boot and (no power, no fans etc.) problem would then be cpu is fried.
