Question about ASUS A7V8X Motherboard
The above motherboard has 3 memory slots and each can hold 1GB. There are currently 2 identical 1 GB sticks installed and working properly. When the third stick is installed, however, the new memory registers and tests normally in the post; then, "Windows will not start." This is puzzling because each stick is identical and works normally when installed in either of the first two slots (both independently and together). Any ideas? Here's my system specs:

You don't mention what type of sticks (ddr333, etc.) The mobo only supports certain capacities depending what you are using. For example, ddr333 is only supported in up to 2 sockets. Maybe you already knew this, but I thought I'd throw it in. It's in the manual, you can download it from Asus.

Interesting I just ran into the same exact problem. I have the same motherboard and 2 1-gig memory exactly the same. I bought 3rd gig to add and it is the same brand and specs of the first 2 gigs. - all from Crucial - Windows wont start all the way, also mouse looks like a big square block instead of usual arrow.
I don't have an answer but do have the exact same problem...hhhmm windows update issue..??

The guest solution was mine. I would say that if the 3rd SIMM socket is bad, then the mobo 'mostly' works. If the 1Gb memory sticks are new, maybe you can return them, re-use in a new mobo isn't recommended due to speed. New ships can take advantage of faster memory & if the old memory chips do work, they will slow down the main chips.

OK, you do have other memory, so to check for a bad slot, your 'legal' [available] numbers are:[expressed in Gb] 1/4, 1/2, 1, 1 1/4, 1 1/2, 2, 1/14, 3.
Other configs are possible, but not with the memory that you say that you have at hand. I suggest that you try 1 or 2 1Gb sticks with the 256Mb sticks. If as we suspect, there is something wrong with the 3rd simm socket, you should see problems whenever you use it.
NOTE: Most boards require the denser SIMM to be in the 'closer' spot.

Sounds like either a bad stick of memory or a bad dimm slot . Have you tried the memory on another motherboard ?

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.
• Install only identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page.
• This motherboard does not support double-sided 16-bit DDR DIMMs.
• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.
