Question about Mach Speed MK8-939A (VIPERMK8939A) Motherboard

1 Answer

Not posting I have a brand new Mach Sped MK8-939A mobo, AMD Athlon 64 3700+ cpu, heatsink and fan for the cpu (purchased as combo), new 500 watt power supply, new sata HDD. I installed all components using the raised pins so the mobo didn't sit directly on the case (risk shorting) turned on the pc, and NOTHING!! No post, cpu fan doesn't turn, no video, CD ROM won't open to insert mobo driver CD, no error beeps. Power light is on, HDD light on case lit. Neither CD ROM nor DVD ROM will open unless I unplug ribbon cable, then with power only, doors will open. Any troubleshooting suggestions? I bought all new inners because my ASUS mobo with AMD 3700+ cpu did the same thing. It was working then on reboot, went totally brain dead. I have tried known good memory and video cards from other machines, but no change. HELP!!!!!

    My understanding is that the only additional power to be connected for the cpu is if is an Intel. I was told that the AMD didn't need to be plugged in separately. Is this not true? On the other mobo (ASUS) it was not plugged in and worked fine. It won't hurt anything to plug it in will it?

    Hey!!! I stand corrected!! Plugging the power supply into the mobo for the CPU worked (some). I guess it isn't for Intel only!!!! Okay, to test it I removed the DIMM and actually got a repeated single long beep. (I assume it means no memory found) Now my ROMs both open with the button, and the power button actually turns the system off as well. However! I still get NO VIDEO! I have a Radeon 9600Series graphics Accelerator card which should be compatible with the mobo according to the MachSpeed website. I have tried another Radeon 9600 card from the computer I am currently using, but still get NO video. Any suggestions again???? The last one made a difference, I am depending on you!!

Maybe a silly question to ask; but did you connect the processor power lead, as unlike some processors this needs a seperate supply.

    I recently bought an AMD chip and noticed in the processor manual that it has a power connector to the board from the PSU.

    Although my chip was not as powerfull as yours, check the documentation that came with the chip and Mobo.

    Try booting in safe mode(f8) on boot up, it should boot in VGA mode.

    The problem is your AGP port driver is not yet installed more than likely, but it should still boot.

    If you get it running try to install motherboard drivers, and reboot.

    Does your board have onboard graphics, if so you have to enable your primary graphic controller as your AGP slot.

    It may be wise to install everything and get it running if you have got onboard graphics then sort out the graphics card last.

What kind of cpu cooling fan can I use in a Acer America ASE380-UD420A desktop computer?

Cooling fan to CPU are come along with the CPU. You can use any other fan, having speed regulator pin, ie, the connector wire to it will have three conductors. Keep a close look at the size and seating screws to its body to the heat-sink of the CPU.

I have a Lenovo 3000I have a Lenovo 3000 J115 7387-A32, I replaced the AMD athlon 64x2 Dual-Core 3600+ with a AMD Athlon X2 5000+ 3200mhz Scoket AM2+ CPU, when I turn on the computer the fan in the power...

I think the first thing to do is go back to the cpu Fan and check the plug and make sure you are on the pins as should be make sure that there isn't any Bent pins . Continue on to the next fan in question.If not then I would not continue Running this machine Until I had the fan problem fixed. It doesn't take long to mess things up. I am surprised that it will run . I would like to have faith in the hardware monitor to propely shut it down.then I would go to the power source Plug on the motherBoard . Check that it is connected good and try it for a short run on then off to make sure that the fans are running like they are supposed to.

Solid amber light in front of desktop, nothing else work

Bad power supplies, motherboards, and front panel connectors have plagued this model since Dell started selling them. I had the same model and after 3 motherboard replacements, 2 front panel fixes, and 3 power supplies it still only worked sporadically. In reality only Dell tech Support has the answer to the specific code as they do not publish them. After much research found out the design was flawed. You can try to keep fixing or you can go the route I did and cannabalize the RAM, video card, hdd's, cpu, & optical drives and purchase a barebones kit that is compatible with your parts. I found one for mine for less than $200. Hope this helps.

Cpu fan runs at high speed all the time

the problem is that the mother board you are now using has a 4th wire that sences cpu temp this allow the heat sink fan to change speed to get this to work correctly you will need to replace the fan with a 4 wire style. what is happening is your not getting a temp siginal back to motherboard so the fan controller think it hot and send full power to fan alll the time the stock fan in hp systems is not very good any way .Get a good heat sink and fan to fit your new board ebay has them very cheap 5.00 to 20.00 this will all so increase you system temp and all get the proper cooling when you really need it.

Fan error

You mite not want to reset this. This could be telling you that your fan is faulty/Dieing. If so then if it doesn't turn off your comp, your CPU will fry from the heat. Try replaceing your CPU fan within your computer. "Cool Master" is a good brand. you can find them at any Fry's Electronics Store.


the short answer is YES you need the additional power to the 4 pin molex.

Post your power supply brand and specs along with the copmplete spec of your PC and I'll be able to give some further advice regarding best option for you

Brand new motherboard wont start up

try taking 1 stick of ram off the motherboard, and boot up with 1 stick in slot 1 or 2.
You should get some beeps, 1 is system Ok.
3 is usually RAM/Graphics problems.
Also try booting with the motherboard setup disk in the CD Drive, it may be looking for files to initialise the Board.
And the obvious, check that all cabling is correct from mainboard to front panel. Power on/off Reset et,c.
View the user manual to see if the board has any jumper/dip switch settings for different configurations.

New cpu but no video output


Dead Mobo?

Do you have both power connectors from the PSU hooked up?

You need both the large one near the ram, and the smaller square 4-pin one near the printer port
