Whenever I try to upload a new sketch to my Arduino UNO R3 board, it gives me this message:

Failed uploading: uploading error: exit status 1
This happens any time the sketch I try to upload is a new one, and it seems the only way I can fix it is by completely restarting my computer. I'm tired of this and want it to end, but I don't know how. Could someone who knows more than me help me out here please? Thank you very much.
If you search here on the forum, you will find thousands of topics with users having the same problem as you.
There are several situations that can cause this error.
Search and you will find one topic that solves your difficulty.
Always look for similar solutions first... on this forum or an "arduino" internet search.
I experience a similar problem (sometimes) when I begin a new sketch, remove a board from the USB or just have long pauses between uploads. My solution (after the error) is to verify my IDE senses my board presence and lists a port: IDE >> TOOLS >> BOARD >> AVR BOARDS >> your board... and IDE >> TOOLS >> PORT >> your port.
If you are using IDE 2.x, you should see two indications of your board (or no board), one is in the upper left area of the IDE, a dropdown to select your board and port... and another area is in the lower right (Arduino Uno [not connected])
