Issues with installing new motherboard

[Celeress]

I just recently got a new motherboard and CPU because i was in desperate need of a upgrade. i want to try and keep this short so here is what i got:

CPU: Intel i3-3240
Motherboard: Asus P8H61-M LE/CSM R2.0

I've never installed a new motherboard before so i made sure to follow the manual as closely as I could. After getting everything plugged in right, or at least I think was plugged in right, I go to power on my computer and am just greeted with a little green light on my motherboard. Completely clueless as to what I messed up, I decided to restart the entire process only to get the same results.

I'm completely stumped right now and have absolutely no idea how to fix this so I came here. What I thik is a important note that I would like to add, however, is that after looking over the manual very throughly, I noticed it has a small 2-pin spot for the cord that connects to the PC's power button. Tracing the cord to my power button.. I realize that it is a completely different set of pins that would never fit in there. It looks like some other front panel USB pins I plugged in with 10 pins but 1 corner missing so it really only has 9 and is shaped kinda like a long L except the corner with the missing pin does not match this fron panel UBS plug.

I really just want to get this working and really hope I didn't overlook/miss something when picking out the parts.. I was manly doing this upgrade just to get a better CPU so i was really only looking for a motherboard that would fit in my case and mach the CPU socket. I also picked up a 4 GB stick of RAM since my old motherboard used DDR2 and this one uses DDR3.

This is my computer:

Only thing I've changed is the power supply (now 450w) and a GTX 650 Ti

Might want to bench it, have a guide that might help here:

I followed that to the point where it says to power it on with only the CPU and GPU installed and I get the green light on the motherboard but no fans spinning like it says should

Try adding a single stick of DRAM

Still nothing, just the green light and no spinning fans. If it helps at all, everything in my computer was working perfectly fine earlier today (before I took it apart to try and install this thing)

Double check that both the 24 pin and the 4/8 pin power cables to the mobo are securely attached

It's a 24 pin and a 4 pin and they're definitely in there

Do you have a different PSU you could try or borrow one to test with?

I should still have my old power supply laying around somewhere but I'd have to find it. Probably won't be able to check until tomorrow. Does it matter that the old one has 350w and my current one is 450w?

What PSU do you have now - the 650TI needs a 400 - if your 450 is a 450 peak then it might only be 350 or so continuous is what I'm thinking

Excuse me, my current power supply is 430w, not 450w. It is the Thermaltake TR2 430w.
And I just tried my old power supply, made the motherboard light come on but still no spinning fans. Only had the old power supply hooked up to the motherboard and CPU, it doesn't have a PCI-E thing or whatever for the GPU.

Update:
Turns out the cord I thought was the power button cable indeed was, and it ended up fitting on the spot on the motherboard that is for the power button. I guess I was having difficulties because my power button cable is a 9-pin and the spot on the motherboard for it was like, a bunch of pins that look all randomly placed cause I guess several different cables fit there.

The cable managed to get plugged in correctly since I got the fans to spin when pressing the power button which was a great sign to me. With this in mind, I decide to plug everything back in and put everything back together. Turning on my computer after this brought me to what I THINK is the BIOS screen and it just simply asked if I wanted like, performance mode or power saver mode etc. for the processor. I got past this screen and what I got next was the "Windows recovery screen." The screen you get if you pull the power cable out of your PC while it's on and I simply pressed "enter" and whoosh, computer is back.

After signing in to my computer, the resolution is a little funky and it starts installing drivers which I assume are for the new CPU and Motherboard. After they finish it has me restart my computer and this time around, it starts up as if I never even opened it up and replaced parts. Computers working fine, I have everything on my desktop, didn't have to reinstall drivers or the OS or anything like that which I find extremely odd. I go to my system properties and the parts are in fact listed there.

The only issue I have now is that my computer is not connected to the Internet and my Ethernet cable is glowing red/orange instead of green. Other than that, it looks like my computer is working perfectly normal even after a new motherboard and CPU were installed which I find very strange. I thought I had to like, reinstall everything as if I just got a brand new PC with a empty hard drive?

Might get on another rig and download the latest ethernet driver for your mobo
