You should have posted each problem seperately as they are unrelated. I will try to answer both.
First, here is the link to the Elite webpage to download drivers for the K7AMA motherboard:)
From the motherboard manual...
The key features of this mainboard include:
Socket-462 Processor Support
¨ Supports AMD Athlon/Duron
¨ Supports 200/266 MHz Front-Side Bus
¨ Two 168-pin DIMM slots for SDRAM memory modules
¨ Two 184-pin DIMM slots for DDR memory modules
¨ Support for 100/133MHz memory bus
¨ Maximum installed memory is 1GB
You cannot use SDRAM and DDR simultaneously.
¨ One AMR slot for a special audio/modem riser card
¨ One AGP4X slot for AGP 2.0-compliant interface
¨ Four 32-bit PCI slots for PCI 2.2-compliant bus interface
Onboard IDE channels
¨ Primary and Secondary PCI IDE channels
¨ Support for PIO (programmable input/output) modes
¨ Support for Multiword DMA modes
¨ Support for Bus Mastering and Ultra DMA 33/66/100/133
Power Supply and Power Management
¨ ATX power supply connector
¨ ACPI and previous PMU support, suspend switch,
keyboard power on/off
¨ Supports Wake on Modem, Wake on LAN and Wake on
Note that there are differenet revisions of the board. Also, if you have one of the 'crossover' revisions with two types of memory slots, you cannot use the 168-pin SDRAM slots at the same time as the 184-pin DDR slots to increase your total memory.
No display can be caused by a number of factors, especially as you do not give the history of the board. Generally you should hear the onboard speaker beep if the computer completes the Power On Self Test (POST). If there is no onboard speaker there should be a connector on the motherboard to connect the case speaker, usually a four-pin connector with two wires used.
If you are not completing POST it could be anything from a bad motherboard, bad CPU, bad ram, bad video card, bad power supply (not supplying correct or sufficient voltage), bad BIOS chip or not just configured properly. If you had to connect the CPU, did you use one that is supported by the motherboard and did you mount it with thermal paste, heatsink and fan?
Most obvious sign of a bad motherboard would be if any of the cylindrical capacitors have swollen tops or are leaking fluids out of their top. Take a good look at the motherboard and all of the pieces on it. I've even seen the copper coils completely burnt. But not all motherboard problems are visible so it could still be a bad board if nothing looks amiss. You would really need a good motherboard analyzer (mine cost $1200) to know for sure.
Next, are the other components known good and tested one by one in another system? You did not give enough information to focus in on what the problem might be. I would suggest you try to connect a speaker first to see if there is a beep code at all, if not it is likely a bad motherboard/CPU. Then try puttting in a different video card, PCI if possible because you might have a bad AGP slot, too. Next try a Boot Analyzer that plugs into the serial port to see if you are getting any CPU activity. There are just so many tests, you might need to have hands on assistance if it is worth the cost. In general try to test each component piece by piece in another (working) system.
