Where can i find an updated driver for SD card reader (Acer x1930 desktop)

I have an Acer desktop X1930 which has an SD card reader on the front panel, its working fine, but only on smaller cards, recently tried a 64GB sdhc card and it doesn't recognise it, so im guessing I need to update the driver.

I tried the acer site but nothing really showing for the card reader unless its hidden within some sort of system driver update - any clues?

Thanks for the suggestion, i took a look there, but.. the none of the drivers seem to relate to the sd card reader, only these look like they might be related:

USB Renesas USB driver
Chipset  Intel  Chipset driver

The others all seem to be display related VGA, Wireless LAN, Modem, Audio, TV Tuner (i dont think these are for the sd card..)

Any ideas?

Normally Chipset / USB driver does the driver for SD Card.

The reader doesn't support your type of card. No driver update will change that fact.
Just as an addon to the above, your card isn't an SDHC card, those only go up to 32GB. Above that you need an SDXC card, and those aren't backward compatible to SDHC card readers. So you need another reader...

Problem eventually located to a faulty micro to std size SD card, so in fact it was none of the above..
