PC won't post

Somebody really doesn't want me having a gaming PC. After getting it all set up, and having it working for the past week or so it's died...

Won't even post to BIOS.

If I remove all sticks of RAM, I get the 1 long beep 2 short beeps on loop. From my understanding, this is the ASUS code for "Your RAM is screwed" which makes sense, I don't have any.

Put any RAM back into any slot, and I don't even get the single beep.

I've come to several possible causes if anyone could give me any insight as to which is most likely, or perhaps know of one possible problem I missed please let me know.

1: RAM is ducked. Unlikely as I'd get the beeps, not silence.
2: RAM sockets are ducked... Same as 2
3: Graphics card / cards are ducked. Same as 1
4: PCI-e slots are ducked. This is the one which seems most likely to me since my understanding of the beep codes is

-startup
-check ram,
-if ram ducked, beep code
-check gpu
-if gpu ducked, beep code

If it can't check the GPU because the PCI-e slots are buggered, then I suppose that'd be the problem.
