Brand New Computer Will Not Post

Guys I need some help.
I just purchased a new system from Newegg, put it together tonight and when I press the power button, nothing shows up on screen. It won't post. Nothing. Everything is brand new from Newegg...

I checked everything I could think of.
24pin ATX properly seated and connected
8pin ATX (2x4pin) properly seated and connected
Video Card properly seated
6pin 2x power to video card properly seated
ram checked and properly seated
I also redid the heatsink+thermal paste
I dont think im missing anything else connected to the motherboard..
I also double checked, the problem is not the VGA card as I have two, and both don't work.

my specs are

Antec P182
Corsair TX650w
Asus P5Q-E
C2Q Q9550
G.Skill PC-8500 2GB-x2 (4GBPK)
EVGA GTX 260
Xigmatek S1283 + AC MX-2

Need some help guys, just spent $1k on this system and I feel I bought a bunch of useless crap.
Thanks in advance!!

Is the little switch on the back of the PSU turned on?

Is the mobo light on?

Yes and yes
The computer will actually turn on, it just won't post..or nothing shows on screen
CPU fan turns, VGA card fan spins...
AFAIK, the PQ5-E does not have any diagnostic LEDs...
I've also checked the ram, with just 1 stick, in different spots/channels with each stick..
my dell monitor won't even come out of powersave..
its not the videocard tho, I just plugged the EVGA 260 back in my old desktop and Im using it right now to type this reply.
Also, its not the power supply, as Im using that right now too...in my old setup.

Do you have a bios clearing switch at the back? If so, check it's not set to clear.

I did reseat the CPU, twice.
I checked the ram slots I used, switching between all 4 of them and the 2 sticks of ram.
Also cleared the CMOS..
no luck
could the CPU or MOBO be dead?

Did you try booting without the ram at all? If you at least hear a beep sequence, then it could mean faulty ram, if not, then it sounds like the motherboard is the problem. When i first bought my P5Q, i had a similar problem, but on top of not posting, i couldn't even turn it off properly, press and holding the power button wouldn't turn it off, i always had to turn it off from the psu. The problem for me was the motherboard, got a replacement and all was fine after that.

Work through the new build checklist.
http://www.tomshardware.com/forum/ [...] -checklist

After the checklist, try this:

Disconnect everything from the motherboard except the CPU and HSF and case power switch. Boot. You should hear a series of long single beeps indicating memory problems. You do have a system speaker installed, yes? My Antec 900 case did not come with one. Silence here indicates, in probable order, a bad PSU, motherboard, or CPU - or a bad installation where something is shorting and shutting down the PSU.

To eliminate the possiblility of a bad installation where something is shorting and shutting down the PSU, you will need to pull the motherboard out of the case and reassemble the components on an insulated surface. This is called "breadboarding" - from the 1920's homebrew radio days. I always breadboard a new or recycled build. It lets me test components before I go through the trouble of installing them in a case.

It will look something like this:

You can turn on the PC by shorting the two pins that the case power switch goes on.

Speaking of the case power switch, if you suspect it, swap it with the case reset switch and use the reset switch to boot.

If you get the long beeps, add a stick of RAM. Boot. The beep pattern should change to one long and two or three short beeps indicating video problems. Silence indicates that the RAM is shorting out the PSU (very rare). Long single beeps indicates that the BIOS does not recognize the presence of the RAM.

If you get the one long and two or three short beeps, test the rest of the RAM. If good, install the video card and any needed power cables and plug in the monitor. If the video card is good, the system should successfully POST (one short beep, usually) and you will see the boot screen and messages.

Note - an inadequate PSU will cause a failure here or any step later.
TX650 is not an inadequate PSU.
Note - you do not need drives or a keyboard to successfully POST (generally a single short beep).

If you successfully POST, start plugging in the rest of the components, one at a time.

That is sort of exactly whats happening to me. I can't turn it off either, have to flip the switch on the back of the PSU...

I don't have a case speaker. The P182 didn't come with one, nor does my previous case...so I don't have any case speaker anywhere : (

Well, if its the same problem i had, sounds like you need to replace that motherboard.

Ok guys after a night of rest and cleared my head, I just realized..
I never put the mylar tape on the backing plate. I think that shorted out my motherboard

I will test it now. But do you guys think the CPU is still okay?

Reply to fruitcake

CPU seems somewhat okay, im not sure yet.
trying to install windows7 RC right now but it is at some blue flowery screen and seems to be stuck there..will wait and see what happens

Reply to fruitcake

ok setup is running. seems like everything is fine.
happy camper here
