I just got all my pieces for my new computer. I've got the following:
Cooler Master 550W PSU, Cooler Master Elite case, Intel E7200, Asus P45 based mobo, Asus Radeon 4850 video, LiteOn DVD-R, ATA133 Western Digital 250GB hard drive (a left over from the past...), Corsair 2GB RAM.
I assembled all the components yesterday. I plugged it in and hit the power button. The green "power standby" LED on the mobo lights up. The CPU fan, PSU fan, and Chasis fan all spin up. I can hear the hard disk start up. I can also open/close the DVD drawer by pushing the button. The video card also has a spinning fan. So, I have power.
After that, I don't get any video. I also haven't heard any POST beeps (might have to plug in speakers? I don't see a tweeter on the mobo).
I've gone through and double checked all the connections, etc. Everything looks set up properly.
I did have some initial problems getting the CPU cooler installed. It's a retail Intel CPU using the stock cooling fan. However, I think it's in place now.

Any ideas on this problem?

Second note: I think I will be rplacing the ATA133 hard drive. The SATA cables are so much nicer and compact. I was being cheap and recycling
 
Do you have a case speaker/buzzer you can plug in? Also, yes, some Asus boards do emit errors through the regular speakers. Did you plug in the power for the vidcard?

If you have both the 20/24 pin main ATX connector plugged in, AND the 4-Pin (or 8-pin) ATX12V P4 CPU connector plugged in, then the board should boot fine (unless it requires more power connectors from the PSU). You could try clearing the CMOS.

You could test the PSU. Jump start it (on the main atx connector, short the green wire with any black wire, using a paperclip), and see if it stays on. If not, then its probably a faulty PSU. If it works then you can proceed with the suggestions below. ***NOTE: The paperclip trick is a simple test for those that do not have PSU testers, multimeters, nor a spare PSU to test with. It is not a 100% conclusive test of the PSU.

Setup everything outside of the case, with the mobo on top of its cardboard box. Plug in only the essentials:
- PSU (namely: main 20/24-pin ATX connector and 4-pin ATX12V P4 CPU Connector)
- CPU w/ HSF
- Single stick of ram
- Videocard if there is no onboard video (along with its power connector, if it has one)
- Monitor
- Keyboard
- System speaker/buzzer

* Use a screwdriver if your board doesnt have an onboard power switch. Jump the two power switch leads to turn the power on.

If it won't post, try different RAM slots. If it still won't post, pull out the ram (so no ram in the system) and listen for error beeps. If none, pull the vidcard and listen for error beeps. If none, re-seat the CPU and HSF, then try again. Report back with results if you're still having issues.

Could be something inside the case that's shorting out the motherboard. Do what enginurd recommended about setting up everything outside of the case. if you get video, something inside the case may be causing a short. Look for a loose screw, bolt, wire, cable, etc. Something that shouldn't be there.
 
I'll give that a try.

I took back my PSU last night and bought a Corsair 750W one. The other PSU was 500W - and did not have the 8 pin EATX12V connector and only had one power adapter for a video card (which is ok right now - but I might enable CrossFire in the future).
 
Son of a gun. One of the memory sticks I bought must be defective. I stripped the mobo to bare bones and got my first post codes (no ram detected). I then added a single stick of ram. No beeps, nothing. I tried the other stick. I then got the no VGA found.

I tried going back and trying the bad stick again - system won't POST with it. I guess I'll have to send this back (bought it from NewEgg). I bought a 2GB kit - so both have to go back.

Anyway, I'm slowly getting this machine running. Thanks for the tips.
 
Picked up new ram from Microcenter and RMA'd my defective ram back to NewEgg (didn't want to wait on replacement memory). I'm in the process of installing software to my machine now.
Later tonight, I might try OCing the e7200. First things first - get the system up and running. Make sure it's stable. Then OC.
 
Nice. You can run memtest overnight on your new ram to make sure its stable, if you want to.
