Question about Mach Speed VENOM V2DP Motherboard
The computer won't power up past 2-3seconds. To get it to power up at all you have to first disconect the power from the power supplie or pull out the power for the motherboard for 10 seconds and put it back in before the power swich will do anything. then when you turn on the computer it only goes on for about 2-3seconds (fans run on cpu case and power supplie fan turn on power light on front and no other lights come on also monitor turned on and blank)and then shuts off. has two "256mb DDR-400mhz-CL3 pc3200U-30330" memory sticks and a "Micro ATX W/350 W P/S" and "sempron 2500+ Socket A" cpu and i also cleared the cmos by pulling out the cmos battery and putting it back in.
We had a similar problem with a compaq (pavillion?) it would get to a black screen but it would beep constantly we pulled the original ram out (we had extra) and it booted up fine the ram that didnt work was Hynix 256mb DDR-400mhz-CL3 pc3200U-30330

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.

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?

I had the same problem once. I took it to CompUSA to have them diagnose the problem, and they said I fried the motherboard or CPU. The fans turn on just because your power supply is on.

I had same problem!
I figured there was something wrong with my memory because that is what the manual says the constant beeps mean.
I bought a new PNY memory stick 1 gb DDR and got the same beeps when i put it in.
So being totally disappointed I tried putting the Stick in the #3 DIMM. I booted up and IT WORKED!
I have not called tech support or tried both 1 & 3 DIMM together but I will try after I set up the rest of my computer.
