Last night I read a post on a forum where the problem was a bad stick of RAM. So I decided to remove one of the 2 (1GB) sticks of RAM and see if the monitor would get a signal. It did! So now I just wanted to test if the RAM itself was bad or if it was just that slot, so I switched around the faulty(?) RAM and the good RAM and it wouldn't boot again, as expected. However, when I switched back the good RAM in, it did not boot again. So now I'm not sure if it was the RAM at all, I doubt that I fried a stick of RAM just by taking it out and I never had problems with the RAM before.
Just today I decided to check if my motherboard speaker was ever installed (this is my first build so I did not know that it was something that had to be installed) and it wasn't, so I installed that to hear if I could get a clue as to what the problem is with. On the next start-up it didn't make a sound. So I'm not sure if it is just not beeping or if I just did not install it correctly. So now I'm at a stand still, I don't know what else to do. I thought about going out and buying some RAM from a computer store around here but I'd rather not waste money on something I don't need. So that brings me here. A friend of mine suspected that it was either the GPU or the PSU, but I really don't know, I had it working for a second without changing either of those things so I'm inclined to think that they are not the issue.
I remember after I came back from another break (where my computer was off for an extended amount of time) the same thing happened, only after like 10 or so minutes of leaving the computer on, the monitor randomly got a signal. So this is sort of a recurring thing.
I've had this computer up and running for nearly 3 years and this is the first time that I've really had trouble with it, so I know that my build is sound. The only trouble I'm having now is a failing hard drive, but the computer was still booting up when it started.
Edit: I've taken a can of air to the inside of the computer to get rid of any excess dust. I paid close attention to the RAM slots as well, this did not work either.
Here are my specs(I just copy/pasted the newegg titles because I'm not sure what info is important):

I have no idea what to do next, so any and all help is greatly appreciated.
