I have this Arduino UNO r3 with the ATmega 328 chip.
The L led is almost on constant, but the TX led keeps, blinking, flickering and goes off.
I have been searching, and it seems like need to burn a new bootloader to my ATmega chip.
I that possible from the arduino IDE or do I need a secondary arduino to do it?
I can only find some stand alone projects, which really, isnt that helpful.
That sounds like you have a sketch loaded onto the board that's outputting serial data and occasionally blinking the LED? Why do you suspect there is a problem?
Burning bootloader requires external hardware - either another Arduino, or a USBAsp ($2-3 shipped on ebay), or some other ISP programmer (the USBAsp is cheap and good - though there are a number of others)
Every one of the listed error, is from trying to upload that sketch:
