Default Suspect Motherboard..

Hi All. I think I have a problem with a motherboard that I hope you can help me with. I bought the motherboard, CPU and memory as a secondhand bundle that I was assured was working. Here are the specs:

M/B - Asus A7V8X ( not MX ) FSB333MHz
Processor - Athlon XP2200+
Memory - 512MB DDR333
Graphics Card - S3 Savage Pro 32Mb PCI

I've tested the CPU, memory, graphics card and PSU independantly in another machine and they seem to be working fine. The motherboard power LED lights up and when I switch on the main power switch everything seems to kick in ( drives, CPU fan etc ) but then nothing happens! The screen remains blank ( the monitor doesn't even come out of standby mode and switch on ), but more worryingly, I don't get any BIOS beeps, just a couple of electrical clicks coming from the speaker! I've left it on for a good few minutes but still no joy. Any help greatfully appreciated!

Thanks in advance,
Salvatore.

Default Um...

Read the user comments. They turned out to reveal this board is very finicky about what you put on it.

I would suggest following up on the problems they have had as a starting point.

Here's the link to the Asus site for that board.

Hi, thanks for replying so quickly! I scanned through the reviews and most of them seem to give it the thumbs up! The only problems mentioned seem to be with the graphics card, in particular the Ati radeon 9700. The guy I bought the board off said he was running it fine with the Ati radeon 9800 pro, so this can't be the problem. Any others ideas?

Thanks,
Salvatore.

Hi, no, I haven't as I don't have access to one and I feel reluctant to splash out on a new Gcard if the M/B is faulty, so I would like to try other options first. I was told by someone that the BIOS settings might be set to AGP and a solution would be to reset to defaults using the jumper settings. What do you think?

Thanks again.

Default indeed...

Since you cannot get in unplug the cord from the wall and remove the cmos battery. Wait about 5 mins and put it back in and fire it up.

OK, hereís the results:

Components ( see original post for specs ):
CPU, PCI graphics card, memory, PSU 400W. All tested independently and working fine.

Setup:
Motherboard outside case on anti-static material ( no shorting problem ). Mouse and keyboard plugged in.

Testing:
Cleared CMOS. Powered on with nothing on the motherboard ( apart from CPU! ). Then tried all combinations of slots for PCI graphics card and all slots for memory.

Result: No change from original symptoms.

Iíve yet to try an AGP card but donít hold out much hope. Iíll try this as a very last resort before I send the boys round to the sellers addressÖ ;o)

Hi All! You wonít believe how, but I managed to get it working..! After clearing the CMOS and not getting any joy, I made the assumption that the CMOS had correctly reverted to itís defaults. I was also pretty damn sure (99.99%!) that all the components were 100% ok and there werenít any compatibility problems with the motherboard and components. The only thing left in the chain was the flash rom itself. Just for laugh I levered out the rom chip and cleaned all of the contacts on the chip with a bit of emery paper. I shoved it back in, turned on the power and hey presto, that single BIOS beep was music to my ears, and she booted up! After 4 days of headaches, all it turned out to be was a dry contact..! ;o)) One to make note of..!

Thanks for all of your input,
Salvatore.
