    Running Windows 7 Ultimate with 3Gb RAM ( 2 x 512Mb and 2 x 1 Gb DIMMS ) - system runs perfectly.

    Upgraded to 4Mb ( 4 x 1Gb DIMMS ) and system will not boot - error message is as follows :

    "USB device over current status detected. System will shut down in 15 seconds"

    And it does ! Restored memory back down to a total of 3Gb, and hey presto, all is well again.

    I have an ASUS A8V Deluxe motherboard - would a BIOS flash update help solve this problem?

    Possibly would solve the problem, you should see if you can find a data paper on the BIOS upgrade and see if it says anything about correcting a possible problem when all slots (I'm assuming) are occupied or a specific configuration is present. I'm also assuming you mixed the 1 gig sticks several different times or tested them just to help make sure there wasn't a bad stick in the bunch.

    Thanks to fairnooks for a prompt response - I'll follow up the suggestions mentioned. Yes, I tried all combinations of DIMMS, all four worked perfectly in a variety of combinations until 3 Gb was exceeded. I actually wondered if the word "current" was the key one - perhaps 4 x 1Gb DIMMS draw a fraction more power ?

    OK, unfortunately it seems I am already running with the lates BIOS so that possible avenue is closed. Any other suggestions out there ?

    I found I would get that error with any bios after version 2019. I also have 4 GB in the same setup, so I just stay with version 2019. I never tried removing ram before to see if that affected anything with a later version. I do rememeber reading something once on the topic though, about it being a ground issue of some kind and people removing their mother board from the case and testing it on a safe surface.

    Anyways, if none of the problems fixed by later versions of bios affect you, i'd try 2019 or an earlier version.

    edit: sorry, i didn't see that it was the deluxe. I'm not sure what version i'd recommend for your board, but on a quick check to the support section of the asus website for your board, it looks like 1017 added this error for over current situations. 1017 also includes a cpu update, so if your decide to try an earlier version, make sure your cpu is still supported.

    Thanks KompressR - the BIOS I've got installed is 1018 Beta 002 - supposedly the latest for my motherboard. Have had this BIOS for over a year and no problems even after a clean installation of 64-Bit Windows 7. Difficulty only occured when I added the additional memory, after which I checked each chip separately. All worked perfectly until all four were installed ! So I reverted back to three Gb and will continue to trawl for an answer. Thanks again for trying !
