This appears to be a deeper problem than can be fixed with advice on here. I suggest you take it for a professional repair. Check the repair estimate with the value of the camera.

Sounds like your card can't keep up. If it's an SD/SDHC card, make sure it's a class 6 or better.

This is also a guessing game. Your experience in the use of the camera? If you are new, I suspect the settings may have something to do. One simple method to prevent your camera from switching off (timed out) is to do some dummy manipulation on any of the buttons on the camera while shooting. eg. press the menu button or turn the wheel every few seconds to keep the camera awake. Make sure the button manipulation does not actually affect the recording of the movie. OR re-set the camera settings to its defaults - (factory settings)

According to the Canon website for error codes http://www.canon.co.uk/Support/Cons....aspx?faqtcmuri=tcm:14-754472&page=1&type=faq it seems like either a mechanical or electrical fault or maybe both. You could try taking both the batteries out (main and clock/memory) and leaving it a while, and also try cleaning the contacts of the camera and lens and try again. It doesn't look too good for you though, maybe it needs a trip to the service centre.

Have you checked the lens AF/MF button? Perhaps your lens is in Manual Focus mode?

One possible cause is the settings -White Balance. Make sure the white-balance is set to auto and check if any changes to your subject and photo.

Have a look here at the Canon Error codes http://www.canon.co.uk/support/consumer_products/product_ranges/cameras/eos/error_codes/

ERR 80: SHUTTER DESCRIPTION: This error occurs in the following conditions. When the CAMERA self-check system detects that the shutter has not been fully charged (ready to shoot). When the CAMERA self-check system detects that the shutter operation sequence has not been completed correctly. When the built-in flash cannot be recharged after the E-TTL preflash but before the main exposure. REMEDIAL MEASURE: Try clearing the error by turning the main power switch OFF and then back ON.

Take it to the repair shop and get a proper fix done.

Try formatting the SD card from the camera. You can find this option in the menu.

Take off the lens cap.

Normally, these lenses do not 'unscrew'. When you push the red button, it releases the lens catch and then you rotate the lens a short ways counterclockwise, then gently pull forward on the lens while holding the body of the camera and the two units separate. It is possible you have gotten some dirt into the lens latching mechanism. Try returning the lens to the locked position, press the red button, rotate the lens to where it stops and then returning the lens to the locked position and repeat several times if the lens does not lift out when you hit the movement stop. This may allow you to get past the dirt. Otherwise, take it to a camera shop, particularly if the camera is still under Canon warranty.

The IR mode is the timer mode.. On top the camera press the AF button while rotating the selection dial. You see the icon on top the camera switch from a single square, to several stacked squares, then to a clock with a been. That's the IR mode. if you press the shutter button you active the 10 second timer, air you have a IR trigger the camera will receive in in this mode.

Try using Canon's software. Digital Photo Professional that came with your camera. If it works here then your problem is NOT your camera but your computer, usually software.

SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

try this one in reverse first open utility and then plug into the pc.

All the Canon's are having this issue. They should do a massive recall. I'm sold mine on craigslist. Canon will repair it for $220. The Canon t2i's are no longer even worth that. I think they've made more off the "no card in camera error" than selling the T2i's the first time.
