I have a computer that:

A ) Won't get past the POST. After it's done checking the RAM, it just stays there.
B ) The screen is full of graphical garbage.
C ) It won't recognize my monitor at all anymore.

I've read that some people have had similar issues where a failing VGA or IGP wouldn't let them past the POST, but they all seemed to have dedicated video cards instead of onboard graphics like mine.

There are no busted capacitors, I tried with different PSU's, unplugged everything and plugged them back in and nothing. It has an AGP slot, so maybe putting an AGP card will solve this problem? I don't want to spend money on something I don't need.

You're not going to know unless you try
Do you have any friends that might have an old spare?

I might have some at the institute that I study at, but even they aren't sure that they work.

The only way to narrow this issue down is to start by replacing the VGA with a known-good card. Most onboard solutions are programmed to put discrete (added-in) VGA cards first. If that fails, try replacing the RAM. Make sure that all of your fans are spinning and are unobstructed by dust, as this could cause overheating, and could have already done so in the past...which could also explain the issue booting. If that is the case, it is probably new motherboard/cpu time.

Diagnosing this type of issue is a trial-and-error process. The only way to get this issue diagnosed as cheaply as possible is to take it to a repair shop. They will usually have spare test parts lying around that they can try, and usually charge a flat diagnostic fee. The shop I used to work at did it that way.
