Mach Speed V2DP Motherboard

If you can, could you check your cmos battery, to see if it's flat.
then come back.

Some boards need the battery to even boot not to just hold bios sttings.

You also have to bear in mind if the proccessor isn't working it will go no further than power up.

Also, removing cmos battery doesn't clear cmos on all mobo's, you have to put jumper across pins 2-3 on JBAT1 terminals and then back to pins 1-2.

Why did you need to clear the cmos; have you done any upgrades?

Check that the CPU fan you are using has three wires going to the connector. This mobo will NOT startup unless it has the third tachometer pin. It does this to make sure the fan is always running to protect the CPU

Look for a ground fault.I replaced my Motherboard and the power stayed on long enough for the fan to turn about 1 sec. So I pulled all the power connections off and started with just the power supply,it stayed on , so the motherboard without the memory, cd, ect. I found the problem to be the motherboard was groundingout (a mounting screw was pulling it down to the case) I burned out my memory stick.

Had the same problem on my system. Still have. My problem was that the capacitators on the mobo are a bad quality. My supplier says every mobo dating from 4-5 years back will experience the same problem sooner or later. only Asus does not.

First symptoms are mysteriuous crashes of the system.

You can check your capacitators. They should have a flat top. If not, they have brursted open and they'll fail.

My workaround: try again and again. Only connect 1 HDD and 1 CD creates a larger change to succes. I myslef suspect it could also be a problem with the power supply not being able to deliver enough (stabel) power.

Better option: buy a new system.
