I have a MacBook, and when I turn it on, it turns on fine, but then it begins to get glichy and then the LCD freezes, and sometimes a beeping sound comes out of the computer. Any ideas?

The beep codes were revised in October 1999, and have been the same since. In addition, on some models, the power LED would flash in cadence.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable

that sounds like a cooked(overheated) graphics card or a bad/dusty connection. this can't be a driver problem if it beeps at the time you first push the power button to the windows loading screen.

I hope he is not getting the windows screen on his MacBook and nowhere did anyone suggest that it was a driver issue.

This means it is coming off the BGA and all you have to do is reflow it and clean the heatsinks
*tip from me i give doing this*
Get AS5 thermal paste
I do not know what you have so i can't give you a guide but i can give you a guide on how to apply thermal paste
This is all i can give you without your model Macbook

is there a pattern to the beeps that repeats?

Do the colors get scrambled? What are the last three letters of your serial number?
