I am not electrically savvy person but I have general idea of what some things are and what they do. I have this nice computer video card that has a broken transistor on the back side and is not working. The reading on it is K1P Z4. I did some googling and some online catalogue searches but that didn't turn anything. There are 2 transistors next to each other and one is broken in half (appears someone has dropped something on top of it) and they are the same size. The broken one is unreadable in the middle but beginning and the Z4 end is same as the other transistor so I assume they are the same. I am hoping any of you can help me identifying it and get a replacement.picture taken with a magnifying glass

It looks a lot like a 2SC945, whose TO92 packaging matches the image you posted.
You may want to investigate this company. They make the type of pins shown here that are very close in application to what you are looking for. Depending upon the mating hole size these may work for you.

Googling
SOT23 marking K1Pthe first hit links to the MMBT2222 datasheet which contains the following text ( on page 2 in a section called"Marking Information" ).and a further table decoding the "ym" date code. The table only goes up to W (=2009) but it's reasonable to guess that Z4 means April 2012.
Seems pretty conclusive to me.
(SOT23 is an industry standard packaging which looks exactly like those in the photo)
And it's a common type of NPN switching transistor so it should be very easy to find a replacement or a suitable substitute.
