Mach Speed 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.

    I have a similar problem. I used the computer the night before (everything was fine) logged off. The next morning went to turn it on and it seems to want to start up okay. Lights are flashing and fans a going, but the screen stays curser no nothing. I tried changing the video card and I still have the same problem. I rejacked the boards and pulled the batery on the Mb and still nothing. Also changed out the monitor that was the first thing. NOTHING. I am going mental!!!! Should I change the MB?????

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?

SOURCE: mach speed motherboard problem

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.

SOURCE: No boot on start up all fans start but no video

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.

Dell c521 won't start blinks amber

A possible power supply failure has occurred. The system has not received a Power Good signal from the power supply. In other words you either have a defective power supply or a device in the computer (i.e. sound or video card) is shorting out the power supply.

My emachine 250-1162 won't power on

Misty, There are lots of things that can cause this issue, but they are all hardware related. The first thing to try and the easiest is to pull out the battery and try to power it up then, plugged in of course. I have seen bad batteries cause that issue but not very often. Also the power supply, the power cord/brick thing, could also be bad to the point where it doesn't charge your battery but still provides a trickle of power that can't power everything it needs to. This is also very very rare The most reasonable issue is either bad RAM, CPU, or motherboard. Ram is somewhat easy to test if you multiple sticks of it in your laptop. On the bottom of your laptop there is generally an easy to get to opening with a RAM icon, memory not the animal, that you can open after unscrewing. If you have two sticks of memory you pull one out see if it works and if it doesn't do the same with the other stick. If that doesn't then it is some other piece of hardware that is hard to test because most people don't have the pieces around to swap out.
Honestly if your battery, power supply, RAM aren't the issue then it's probably best to bring it to a computer repair shop. They have the hardware needed to find what is wrong with the computer, like extra CPU's, power supplies, etc. Also once you get past these 3 items you have to pull the entire laptop apart to get to it which is pretty hard for someone not experienced with it. There is a lot of screws and a lot of the right amount of pressure in the right spots. Also once you get past these three items the replacement cost of the hardware is generally not worth fixing, you are better off just getting a new laptop :(.
If this laptop is still under a warranty then give them a call and they will cover it because this is definitely a hardware issue. Hopefully this helps more than it confuses.

Computer shouts down in 15 to 20 seconds after starting

The specs say the PSU is ATX compatible. Whether that is for the connector only or for the whole power supply is something you will have to determine.

If you have an ATX power supply handy (like in an old computer) give it a try. This one is only 300 Watts so it won't likely be expensive to replace.

HP Pavillion a1514n Won't Turn On

Yes even with the green light on it could still be the power supply. Have you pulled the power, opened the case, and pulled the BOIS battery? Could be the BOIS needs to be reset. You might also pull all the memory chips, turn it on and see if you get a beep code. I have had that happen in the past. Then I would replace the power supply (if you have an old one laying around use it to test, with just the MOBO plugged in). If the power supply fails, that leaves only the mother board as the issue.

Good luck, I hope one of these suggestions works for you.

IT Won't power up.

Possible failure of the main power supply unit which is a switch mode power supply.( SMPS).
You need to disconect the power supply to the printer and open the panel to check the SMPS unit.

Please check on the link below for tips to check the SMPS unit. If this is not possible check with a power supply unit to confirm before you order.
