A:AnswerBe careful
You say pentium that is an old processor the sd card slot may not handle the sdxc format it is higher than 4GB so the file size is more than it will handle
I was using win 7 with the sd card slot and learned I needed a USB insignia card reader
It's cheap so get that instead of hassle if the sd card reader will not read the faster cards
It's not a OS problem it's hardware
A:AnswerPlease be informed that as per the SanDisk® compatibility tool this camera supports SDXC Memory Card of upto 128GB capacity. However, I would suggest you to contact to the camera manufacturer to know the maximum capacity of SD card supported by this camera.
