I'm having problems starting up the PC with this MoBo, when I press the power button the DVD drive blinks constantly and the HD LED stays steady. I tried clearing the CMOS, removing all cards, HD's, even RAM, I don't get the blip when you turn on the PC, I plugged another working Power Supply with the same result.
Could it be the motherboard or the CPU, I don't have the means to test the CPU, if anyone has what the constant blinking of the DVD drive and steady HD LED means...

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
one bad/faulty lead can cause a computer lots of problems try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty hope this helps
Eject any disk from the DVD device.
Turn the computer off.
Disconnect the "data" and/or the "power" connectors from the DVD-ROM.
Turn the computer on, and see if it starts when the DVD-ROM is not part of your system.
If it starts, then your DVD-ROM needs to be replaced.
Before you started disconnecting everything, did you notice whether the CPU fan was running or not?
If it failed for any reason, the CPU is fried; none of them will tolerate the lack of cooling for very long.
Also, bad memory can freeze a system for sure; if you have friend using compatible memory, beg him to let you swap yours into his board and vice versa. I've found failed memory more times than I can count and finally learned to substitute early and save a lot of time troubleshooting stuff that wasn't broken.
It pays to own a cheap multimeter so you can check the individual voltages from the main supply since they can very surely fail piecemeal and any outputs used must be there otherwise the train won't leave the station. Most supplies will have the available outputs lised on them.
Don't know in which country you reside but in the US, you can buy a usable digital meter for <$20 US any time and if near a Harbor Freight, they often have them for 3 lousy bucks.
BTW, the CMOS backup battery is way too young to have failed; three years is pretty much a minimum and I have replaced 8 year old batteries that finally couldn't hack it any longer.
I hope you know to take precautions before touching anything inside to discharge any static charge you might have from carpets or clothing.
Touching any part of the bare metal chassis after gaining access is adequate.
try to find new mobo and pls do not choose ECS, what the hell it is... i have the same problem, all the way that i know, have been tried.. but nothing work.. the problem is still exist. bellow is the way i try to solve the problem, may be you can try, i hope it's will help you, if you are lucky :).

#3 Remove all Cable power from HDD, Removable disk, DVD/ CD ROM, turn on the computer and let's it on few hour, if it's work well, the problem i guess is in your PSU(power suply unit), replace it with the good one. if not work, Just replace the mobo with the new one.. n dont choose ECS again.. ok good luck :)
