Second Question
Hey guys I just finished installing all the parts into my case, and I have to wait until the next month to receive my CPU. I couldn't buy everything at once, seeing as of the time the parts I bought were at such a good deal.

Is there any way I can just turn on the Pc and see if anything is running like fans. It would make me feel so much better as this is my first ever PC build and I'm very nervous at if I did everything right.

Second Question
Also I need to get reassurance, because I kept thinking of something I did. So I tried to get the first stick of ram in. I put it in once, but then I didn't really hear the click on one of the sides so I took it out. Then I tried again, and maybe I was nervous and trying not to push too hard so I didn't hear the click again, so I took it out once more. The third time it went in, I just needed to push a little. My question is if the 2 times before when I took the ram out could've damaged it? I feel like not getting it in the first time makes me feel like I would've scratched it if I didn't get it right the first time. In my head I just kept thinking what if it the ram is bad now just because I didn't get it right.

Well, this is building exactly backwards. A build should start outside the case, with only the CPU, RAM, and a video card installed onto the board, if the motherboard does not have onboard video. You hook up the psu to the board, hook up the monitor, and do a boot up outside the case, to make sure the board will POST. If it will, then you install it to the case, and hook everything up. If it doesn't, you start trouble shooting from there with all the issues that could be happening inside the case already ruled out. A common problem novice builders run into is mounting the board correctly. But, to be fair, it seems that things have come a long way over the years, and bad boards, memory, and cases that are a little confusing to mount a...

1 I don't think so. I think some newer boards allow you to power on w/o cpu to update bios, but afaik, the cpu would need to be in boards that don't allow this.. Sure the fans aren't broken though!

2 If plugging in a stick of ram the wrong way (with no forcing or broken plastic or staic)... DID break it, you would be well withing rights to RMA it. DIMMs are designed to bee foolproof, and only fit in one way.

Yeah the M5A97 R2.0, says it has Flash Bios, but I don't know if the CPU has to be the slot to still run.

Can any confirm if it at least safe to try to turn the PC on without the CPU. Would I damage anything?

A common problem novice builders run into is mounting the board correctly. But, to be fair, it seems that things have come a long way over the years, and bad boards, memory, and cases that are a little confusing to mount a board into, are rare these days. But still, I always prefer to see if the board will at least POST before I go to the trouble of installing in a case, thats my personal preference.
If you try to boot without the CPU, not much will happen. Fans and lights will come on, drives will spin up, but that doesn't mean anything. Even in the most worst cases, if you have read very many posts here about booting problems, the one thing that people always, and I mean always start out saying is "lights come on, fans and drives are spinning, but I get no video output" (which means the PC is NOT booting or even making it to the POST screen) so turning it on at this point without a CPU installed won't really tell you much. But it won't hurt anything either if you do. Memory is made to be taken out and put back in, and in a new board, the slots indeed can be very tight. I am sure you are just fine.

Thanks for the response. Yeah it was weird when I was setting the motherboard on the standoffs. Are the standoffs suppose to go through the holes? Because they didn't in my case. They were like in between of the hole, then I screwed them up.
