PCI card not been detected via Windows.

hi

if you want to go for then only you can put any Nvidia Pci card

or

try to run motherboard drivers hope fully sound will come

Sounds like your ram is on the blink

From the Asus support site.

If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:

- System BIOS (including motherboard, add-on cards, etc..)
- Motherboards resources
- Memory mapped I/O
- configuration for AGP/PCI-Ex/PCI
- Other memory allocations for PCI devices

Different onboard devices and different add-on cards (devices) will result of different total memory size.
e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.

On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.

This limitation applies to most chipsets & Microsoft Windows 32-bit version operating systems.

If you install Windows 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met: 1. The memory controller which supports memory swap functionality is used. Chipsets later than Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture support memory swap function. 2. Windows 64-bit OS which can address more than 4GB memory.

Get drivers from nvidia.com; If that doesn't work reinstall windows and do the same.

ASUS EZ_PLUG is optional for SLI mode...this model of your motherboard has an SLI that connect 2 video card using pci express...if this is only you problem for bugging the EZ_plug not connected,you can disable that in BIOS setup...

this site has a list and downloads for your motherboard drivers could not see firewire that may be in packaged in one of the other drivers

I went through your bios manual three times & did not come across a setting that gives you the option as you listed above.
What I did come across & triple checked your Manual Pg. 2-28 section 14. Asus EZ selector card connector (144-pin SLI_CON.
When using two PCIE SLI cards make sure the card is seated correctly & set for Dual Video Cards. (extreamly important).
Pg. 4-34, section 4.4.9 SLI mode Recommend kepping to Auto. Than the Bios detects the setting of theSLI selector card.
Refering to the sentance above the manual recommends all settings be set to Auto. Your Bios will do the rest. If for unknown reason you no longer have your manual you can download it from Asus. You'll need to fill in the 3 windows under, Please Select the Product.

Make sure that you have the lastest Firmware installed in your BIOS.

Also run Windows Vista Upgrade Wizard before installing Vista to check for compatability.

Note: Vote for me......

Yes, you do. Your board was built with the idea to use 2 graphic boards to get great video


NVIDIA® SLI™technology revolutionizes PC performance by combining multiple PCI Express GPUs in a single and scalable system! Gamers and hardcore enthusiasts know that dual GPUs mean increased, supercharged 3D graphics and performance

If your CPU or memory were an issue your Asus board would sound off with BIOS beeps. Asus uses the Award BIOS & you can see what these beeps mean at the link below. Regaurding your PC not able to boot is an issue with your PCIE/PEG video card-in relationship with BIOS setting & the SLI switch card mode that came with your board. When running 1PEG video card you must set this in the BIOS to Auto & you need your SLI switch card connected in its slot. By default, the EZ Selector card is set for a single graphic card. When you install dual PCIE graphic cards on A8N-SLI series motherboards, please make sure EZ Selector card set to the Dual Video Card side and properly inserted.

Will come in handy.
