help! No video @ boot. it's the mobo

Someone please help!

I have an Asus a7n8x Deluxe Mobo, an ATI all in wonder Radion 9700 video card and an AMD 2800 (333 fsb) cpu.
I get no video at boot and I've tried erasing the bios (CMOS)
and reading the whole manual. but still nothing
all of the jumpers are at default and the RAM is it's correct slot.
I also tested the video card, cpu, hard drive and RAM on a friends pc who has the same Mobo, and everything worked perfectly.
note: the motherboard is new and was in it's original factory box, everything is.
what else can I do?

My best bet would be a faulty AGP slot, since you have the cpu an other components tested. Before you confirm the source of the problem,, it is wise to get a working PCI card and do a bench top test with the barebone system and see if it works, If it works, chances are your AGP slot is faulty.

did it ever work? Are you sure you have the power switch header connected properly? What actually happens when you power on the system? do you get power to the fans and drives? can you hear them all running?

yes I tried a Nvidea 64mb PCI video card and still no video.
and yes the power supply is sending power to all my drives. cpu fan running and everything. I can even hear my Hard drive trying to access.

Have you tested the monitor? Sounds like its booting, you just have no video signal, this would suggest to me that the monitor or monitor cable may be faulty.

Out of curiousity(and before someone blames it anyway) what is the size, brand and model of the Power Supply?

the monitor works fine i tested it with other pc's and i've also tried 2 other monitors compac and a new nec. also I have an s-video out on the video card and I connected it to my tv. but nothing.

the power supply is a Power Man FSP300-60BTV (300W)

It only worked once and when it did I went into the Bios and set everything up according to the manuals os the mobo and other components then I hit save and exit and when I restarted there was no video again. so thats when I tried to reset the CMOS.

That PSU is a bit small. It only has 15A on the +12v rail. 17A is pretty minimum these days.

Here's the specs http://www.fsusa.com/Product/FSP300-60BTV.pdf

yeah but that psupply was given to me by that friend who has the same mobo and videocard that he used to used a month ago and he has a coolance case with water cooling and like 3 hard drives i'm only running one HD and one CD-rom

Well, try this. Use an old video card(something much less power hungry than the 9700)
Try barebones booting with just the essentials; a video card, one drive(floppy if you have one), one stick of RAM, keyboard and mouse.

Could be the nForce 2 bug.

tried using an old pci video card and just essentials still nothing

If you've have that black screen problem right after changing settings in the BIOS, then it's a clear case of the nF2 bug.

Other tips to try & recover the card include taking out the mainboard's battery, then clearing the CMOS.

A good way to avoid that bug is to enter the BIOS, change your settings, then "SAVE Changes". Only once it is saved, choose "EXIT" to reboot the machine. Do not choose "SAVE & EXIT".

what does it mean to flash the bios?
what would happen if I did that?
is there a seflf extracting Floppy i can make that would fix the problem?
cuz I tried that "holding down the insert key" thing to fix the bugg but that didn't work either.

A BIOS (Basic Input Output System) chip that is capable of being written to by software or code. Older BIOS chips required that the chip be replaced. However, with the flash BIOS you can boot with a special disk or execute a set of instructions and update the BIOS without having to even open the case.

Basically, you get the updated drivers from the motherboard manufacturer's website, place those on a disk along with the flash utility, boot to the floppy, and you would type something like:

flashutilityfilename.exe <updatedbiosfile>

It normally takes about 30 seconds I believe.

You can get the BIOS updates from here:

You will need the Award BIOS flash utility

Check the PCB revision # on your motherboard. This is normally located between one of the PCI slots in white text. This will help you determine which BIOS update is the correct one for you.

so i've tried the BIOS flash...
... and nothing.

this is so frustrating.

I called asus but all the reps were busy and they never called back so they might call tomorow

You can't flash the BIOS if the machine will not POST.

This sux!!!
if I can't fix this mobo by saturday I'm gonna throw it in the air and swing at it with a wooden bat.

to all of those that are members at techspot that tried to help me with my A7n8x deluxe, thank you very much. I couldn't fix it so I called Asus and I sent it in for repair. but thanx anyways for all your help.

If you happen to get a replacement card, just remember when you're fiddling around in the BIOS to "SAVE CHANGES" & then EXIT. Do not choose "SAVE & EXIT".
