Ok, I checked the manual and everything.. checked the Bios jumper settings.. The Front Panel/etc setup area (fine wires for Power Button, Reset, etc).. The Power supply to devices and Mobo. The DDR Ram is new (mobo only uses DDR).
The mobo says it supports Socket A AMD Althon, Althon XP (Ya see I'm not sure if the bios needs an update for this.. the mobo doesnt start up without a cpu.. Is it supposed to?)
I checked the power cord and all that stuff also.. The Power supply is 300w.

Here's what happends..
I plug the computer in.. I press the Power button.. The lights on the CD Row, Computer, etc flash on for a split second... nothing starts.

I checked the Reset CMOS to see if that would help.. nope

Quite annoying really

The motherboard brand is Chaintech (yea, i know it's sorta not very popular, but it's the one he picked out for a good price)
Chaintech 7KJD Information Official Website
^ go here to check the details on the board.



Useing new hardware with the comp..
80gb seagate 7200 rpm hd
1.0ghz amd althon
256mb DDR ram
64mb Geforce 4 MX 440
Linksys NIC
300w Powersupply

Wolfmight, im glad u picked AMD, here is your reward, lol.

www.amdforums.com

This is pretty much your AMD community, and they have a entire forum for your motherboard company, so just sign up, and post there.

Oh, and then go into the Folding forum, and download the client, and start fighting cancer for the AMDMB team!

Check your motherboard is seated properly in the case. Try loosening the fixing screws and lifting the board slightly off the mountings, then switching on.

Oh and is it an atx power supply?

[Wolfmight]

Yea, ATX powersupply, and it says 2.03 (P4) next to it.. This only powers intel chips!??

the mobo is an amd socket a

[Evil Gemini]

Its the jumpers man. If its not that get another board

When you say nothing is starting, does this include the cpu fan?

Yes.. after pressing the power buttons all the lights flash on for a split second.. that's it.. Everything doesnt start.

Either the motherboard is not responding with a 'power good' signal (the PS shuts down without this) or the PS is being overloaded/shorted (this also causes the PS to shut down).

Try disconnecting all the power leads except the one to the motherboard. If the same thing happens, the problem is either the PS or the motherboard. If it powers up, you have a fault on another device, or the connections to it, check the connector to the floppy drive in particular, it is easy to get this one pin over with some drives and you end up shorting the PS.

If you have determined that the probelm is the MB or PS, if you have another (good) PS, try that one, same result means faulty MB, power up means faulty PS.
Alternatively, try this PS with a MB you know is good, this time power up means faulty MB.

how can a Ps overload with that? i was running a 2.4 GHz 400 FX5200 1 DVD-Rom and CD-RW and a 80 Gig HDD and 1 90 MM fan he has a 300w PSU im sure it should be able to run that Comp unless the PS is bad or gone bad.

EDIT: well i checked around and found that they do make PSU's for only Intel or AMD and well from what u said that Power Supply is Intel P4 only from what im guessing though to make this mistake is hard since when u buy the parts its labled or in the specs it tells you whether it supports Intel, AMD, or both.so if u keep having problems go and pick up a cheap 300w AMD power supply or u can find a cheap one at googlegear.com or newegg.com

All of this talk about BIOS.

You guys never knew what it was like in the old days, when the BIOS chip didn't exist. A BIOS is just a HUGE macro of commands that tells your computer how to boot up.

In the old days, you had to type in the "BIOS" instructions by hand, in DOS mode. And hope you didn't have any typos. Windows wasn't invented yet. Windows is actually a huge shortcut for everything that was manually typed in, years ago.

@pitbul - most intel MBs require an extra power connector, amd MBs don't need it. If the connector is present it will work with both types of MB. You can overload the PS by shorting 5V or 12V to ground - instant overload.

@spindulik - bios chips have been around since the first pc's, you have NEVER had to type them in.
