Can i download video from canon a590 to pc?

1. Try to format the card in the camera. It should give an error when faulty.
2. Put the card in a pc with cardreader and download this testprogram.
3. Run this program to test the memorycard.
4. Delete afterwards the test contents or re-format it.

SDHC cards go up to 32GB, which puts the upper limit on the size of cards you can use on the A590. There shouldn't be any problem with a properly-functioning 8GB card.

Don't use regular alkaline batteries (even though you can...) It's a pain to splurge for the more expensive lithium or photo-specific batteries, but they do last. I take A LOT of pictures with my A590, and can usually get several hundred shots out of a set of good batteries. Try Energizer's web site for a coupon, sometimes they have them available.

Sending it to an authorized cannon repair facility. the lens must be replaced.

Use a separate card reader to download your pictures.

of course not. What's your problem actually? Have you correctly connect camera to computer? Or does you camera have a memory card?

hello again after researching i did find out that there is about a 3 second delay if using the flash option did any of your delays happen when not using the flash ? also does this happen when using the camera in auto mode ? turning the knob on the top to the green auto mode i'm thinking it also could have to do with your shutter speed or try going to the menu and changing the shutter speed to a faster speed your self then taking pictures in av or tv mode. here's a comment from a review on the PowerShot a590 that might help. Camera performance is very good. The PowerShot A590 is ready to shoot after a 1.2 second delay -- pretty snappy. Focus speeds were very good, even in low light situations. Shutter lag wasn't a problem, and shot-to-shot delays were minimal, except when you're using the flash, which is slow to charge. The camera can shoot continuously at 1.5 frames/second until your (high speed) memory card is full. The A590's battery life is 10% better than its predecessors, and is well above average for its class. The camera supports the USB 2.0 High Speed standard, for fast data transfer to a Mac or PC.
and if you still have the problem with out the flash then the only other solution is a faster flash memory card there's cards made just for digital camera's that store pictures and format quicker.
hope this helps your enjoy your camera.
