New computer trouble

[Nick601 0]

just bought a new Abit AT7 Max 2 motherboard

 

also bought an AMD XP 2600 Processor and 512 MB DDR400 PC3200 Ram

 

plugged everything into my new case and powered up

 

the fan on the motherboard bios span up and worked, the fan on the graphics card worked, all the cooling fans in the case worked and the hard drive span up aswell

 

the lights on the master and slave cd drive lit up but stayed on

 

also nothing appeared on the screen

 

i have tried re seating the memory, changing hard drive cables, taking battery out of motherboard and resetting the CMOS etc

 

nothing

 

 

any ideas?

whats wrong

Try this to see if you get any kind of POST beep error:

 

1) Remove all the expansion cards, this means graphics, sound, lan, modem, etc....

 

2) Remove all sticks of memory...

 

3) Disconnect all drives from the power supply, leaving only the motherboard ATX power connected.

 

4) Disconnect all data/ribbon cables from the drives.

 

5) You should now have a stipped down machine with only the power to the ATX main connector, the CPU and Heatsink/Fan on the motherboard. Any onboard items is ok as we're trying to troubleshoot down to a specific item.

 

Now what should happen is one long beep indication that either the memory is bad or can't be initialized properly. This is what we want to hear. This would indicate that the motherboard/bios/cpu are being detected properly.

 

Now insert the stick of ram after powering down the machine and unplugging it of course, and then power it up and see if you get any other POST beep error code.

 

If not and you only get the fans to power up then I'm going to suspect bad or incompatible ram.

 

If you get another, different post beep error, it should be one long and two or three short beeps indicating that the graphics card can't be found or initialized.

 

Now if you've gotten this far try installing the graphics card and repeat. Keep doing this until you find the part that isn't allowing your machine to post.

ok plugged the speaker in

 

and unplugged all the data cables add on cards and hard drives and cd drives and also took memory out

 

still nothing - no bleeps

 

also reset cmos again

 

nothing

Then I have to suspect one of three things, the power supply, the cpu and/or the motherboard.

 

Do you have any other known good parts to check this out with ?!?

 

If not then it maybe difficult without finding a shop that can help you out here or some other kind soul perhaps

the power supply is also new

 

i could try an older power supply in there

[Nick601 0]

ok tried different power supply and still nothing

 

totally pi**ed off

[jmmijo 1]

Then all you can try now is the CPU on another motherboard and/or another CPU on this new motherboard

might aswell put my mind at rest and give it a go!

i had a problem like this one time my friends computer. Turns out he put one to many mounting posts in the case and the extra one grounded out the motherboard and fried it.

I hope im not getting too basic here, but have you made sure your brightness and contrast controls on the monitor are set correctly? Thats the first thing to check for a black screen.

 

You also didnt mention if you installed a new OS or if swapping HD from one system to another.

Had a computer once acting similarly. Reset button was stuck. Unplugged the cord and everything was fine

Pull th motherbord out of the case and run it in midair while you hold it. this will determine if you had something grounding out. I'v seen this a few times.

well i called the company today and they said send the processor and motherboard back so that is what i have done, when i get a replacement or have the same ones sent back if there is nothing wrong with them i will test them out of the case first

 

the monitor stayed on low power standby so it wasnt a case of brightness settings etc
