I can fix this by going into my garage and flipping the breaker for my room from on to off to on.
This means you're either overloading the branch circuit serving the outlets in the room, or possibly have a faulty breaker that's tripping prematurely - is the TV the only other item using power in the room? Just a PC and a TV overloading a 15 AMP circuit (typical for an outlet branch circuit) is unusual unless something is wrong - does it affect any other objects in the house?
Add up the power draw on the objects on the circuit and see if it comes anywhere near the rating of the breaker - if not, try replacing the breaker. You may have to turn the breaker off and go around and see what's powered down: sometimes circuits may not be laid out in a logical manner, especially in older homes: I live in a 110 year old house and the logic of the circuits baffles me sometimes. If the power draw shouldn't exceed the breaker's rating, and replacing the breaker doesn't fix the problem, then you have some problems in your wiring: have a competent electrician take a look at it: this could be a dangerous situation.
If it exceeds the rating of the breaker, don't replace it with a larger one (bad idea) - you'll have to either have another circuit put in (best) or run a cord to another existing circuit (not a good solution, but works for a temporary one - use a good heavy cord, though.)
