I recently bought a new dell xps 8700 which im now having a problem with. Yesterday when i got home from work it was powered down(i never turned it off), upon pushing the start button nothing happens. Ive reseated the ram but no go. There is a button on the back of the psu which when i hold down will spin the fans. But will not start the computer. I changed the psu but same issue. I can see a light on the mother board that is on when plugged in called aux power i think.

Step 2: (Or even step one, any order is fine really.) Double check all connections, completely remove and reinstall if need be.
Step 3, which may not work as wiring may be different: on the I/O jumpers unhook reset and power, plug reset into the power pinout, if this works, your switch is bad and needs replaced.
If none of the above, either RAM, which you already checked, so that shouldn't be an issue, or the like, Don't dig too deep, I guarantee you that your problem is simple. But I could be wrong.
Let me know your progress and details, I'll help where I can.
Do not start attaching/detaching/moving any components inside the computer case. It's more likely to void your warranty than fix your problem.

As long as the computer is under warranty you should not try to repair it yourself, you'll just risk losing your warranty.
Detaching and attaching all the cables outside the computer is ok, but trying to repair a computer that's under warranty by fiddling around with its insides is something only a pro should do.

A single click when it's plugged in might be a natural sound. I remember I used to have a PSU that would leak a bit power when plugged in and cause all the fans to move just a bit.
A constant clicking shouldn't happen. Most likely cause for constant clicking would be some motor that's stuck (fan, hard disk, or DVD drive), but none of those should have power on.
If there's some error in the computer, some motherboards do beeps to tell you about the error, but that would be beep -like sound, not clicking sound.
EDIT: If the Dell support OKed switching the PSU, it wouldn't hurt to also spend a few minutes testing all the cables inside the computer to make sure they've been attached properly.
Normally I'd also recommend resetting BIOS to see if that helps at all, and maybe trying to detach some components that aren't required for booting, but I think in this case it's better to do those things only if Dell support tells you to do it. /EDIT
Where is the clicking sound coming from? The PSU, HDD, optical drive, motherboard, somewhere else? Is there a pattern to the clicking? If so, what is the pattern. Clicking from the PSU > bad PSU, HDD clicking louder than normal (Can you easily hear it more than a foot away from drive) > bad HDD, Optical drive clicking, bad optical drive or check for a misaligned disk and remove disk . MB clicking/beeping is an audible error code.
If the PSU and CPU fans work that normally means the PSU is ok. There is also an LED on the PSU. It's supposed to be green if good, red if bad when the button is pressed.
If the fans don't run the standard method to test a Dell PSU is to unplug all PSU cables except the main motherboard cable. This includes the removing the CPU power connection on the MB. Unplug all external devices except keyboard, mouse and monitor. Press the button on back of PSU, Do all fans run? > Good. After each test, plug something in (CPU connection first!). Push button. If fan's don't run then you just plugged in the faulty device.
You can also try resetting the BIOS.
1. Unplug PC from wall.
2 Push the power button to try to turn on the system. You're trying to drain the capacitors.
3. Remove the battery from the motherboard.
4. Wait 10-20 seconds and put battery back in.
6. Plug in system and turn it on.
If it works then you fixed it and might want to replace the battery. If you call Dell they might send you the battery or send a tech with a battery.
If you call their warranty support and feel like ranting then keep the rant focused on your PC or Dell. Don't attack the phone tech. Get them on your side. Let them know you aren't angry with them. If you can't understand the tech ask to be transferred to another tech and state why. You won't get a level 2 tech or their manager.

^^them old things
But ive never known a windows pc HAVE to have a keyboard plugged in
But like everyone else is pointing out. bugger trouble shooting you paid over the odds to buy dell, so just phone dell and tell them you want a replacement as clearly with a problem its not fit for sale and should be replaced.
This post is all my opinion, but I welcome debate on anything i have put, however, personal slander / name calling belongs in game

Warning! Using a fire extinguisher on your computer will void it's warranty.
In the end there should only be two things that should make any sound on the motherboard. The CPU fan and the beeper. If the sound isn't coming from them then that clicking noise is most likely an electric short and the motherboard or whatever is clicking needs to be replaced . With an electric short on the MB then the CPU and RAM might also be damaged.
Call Dell.
Every board in my house does this by default: Gigabyte z97-hd3, Asus a88x-plus for the active boards. It can be changed in the BIOS menu. I like this feature for desktops, should I wish to change them to servers in the future I can just disable it.
