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.

(Stupid question to ask, I am aware, but it has happened to me occasionally in the past - I have a color perception problem)

Are your mouse and keyboard plugged into the right slots? If the keyboard is plugged into the mouse port and v.v., then you will boot to a blank screen.

OK, hereís the results:

Components:
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! ). Tried all combinations of slots for PCI graphics card an all slots for memory.

Result: Nothing!

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)

Check the power cables to the monitor to make sure they are not loose. Make sure the monitor is connected properly to the graphics card in the back of the computer. If this fails, change the I/O address on your network card to an unused slot and try booting again.

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.
