Got a day off. Was really looking forward to building, testing and overclocking my new system.

 

Unfortunately I have been scuppered. frown.gif

 

Components:

 

MSI Z77 GD55

8GB Corsair DDR3 1600

I7-2700K

Phantek ph-tc14pe cooler

VTX3D 7970

 

Paired with an OCZ 700watt power supply and Coolermaster Stacker 832. Motherboard power LED lights up. Press it to post and the phantek fans spin gently as does the front and back case fan. The GPU fans flicker as does the PSU fan.

 

Also the front panel connector for the power LED is 3 pin when the corresponding mobo connector is only 2 pins!! This shouldnt affect powering on from the motherboard directly however.

 

Whats going wrong?? Please help I have my sad face on.....

Disconnect the power LED and double-check all wiring. Loose cable, loose ram stick, lack of cooling paste for the cpu or improperly installed heatsink

 

It really sounds like a bad wire somewhere but if everything checks out start replacing components. See if you get POST without harddrives connected, then try with only one RAM stick. Swap the RAM stick. Try your old PSU. If you still get the same problem it's either the motherboard or CPU

Would a lack of cooling paste or improperly installed heatsink cause it not to power up?

 

It wont post with just one ram stick and onboard GPU either. Tried the PSU again with my old system and that seems to work (after a 2 second delay)

 

How can I tell if its a motherboard or CPU error?

Just a hunch here but try putting the ram modules in the other bank. If they are in slots 1-3 move them to 2-4 and try again. I have worked with boards where the first bank (A) would not post with two modules. Placing them in the second bank (B) or filling all four slots resulted in a good post. Many boards provide both a 3 pin and a 2 pin power LED connector. Please look adjacent to the FP connector block, there may be one.

 

Make sure your Primary 24pin and secondary 4/8pin main board power connectors are well seated and properly connected to the board and make sure you have plugged in the PCI-E power cables to the Video card as well. (Just double check all of these). Remove any expansion cards other then the graphics card.

 

Please post back your results.

Perhaps the current BIOS on the mainboard does not support the i7 2700k cpu. Some of its older BIOSes do not. If your board was delivered with one of these older BIOS's you may need to use an older CPU to update it or bring it to a shop to flash it for you to the latest. Check the MSI user to user forum for more info.

 

"For full 2700k support, it needs a UEFI/BIOS version that properly supports it to be installed." You would need Bios 1.2 or later I think.

Maybe.....

 

Best of luck!

Z77 came out after the 2700k though!

 

Grrrrrrr..........I give up. Board RMA'd

According to the cpu support list for the mobo the Core i7 2700K is supported since version 7751v11.zip.

Well a last thing you should consider is to test your main components outside the case...

Put your motherboard on antistatic mat (or in worst case above the antistatic bag that came with the mobo)... plug the corresponding psu conectors (as mentioned by PoleCat), be sure to use the correct 4/8 cpu connector and not a 4/8 vga connector from your psu, then turn on your mobo directly from the power on pins on the main header... you can use a jumper to quickly short the power on pins until the fans begin to spin.

 

Regarding the thermal compund, well unless you really did a bad work applying it and installing your aftermarket cooler then I would say that in the worst case you will only have bad temperatures but your system should power on and post... in the other I see that the Phantek ph-tc14pe can handle three fans :thumbup: but I'm wondering if one of those fans have a 4 pin connector like the one that comes with the stock fan cooler... so check that

 

Some motherboards will power down itself if the cpu fan isn't detected... just as an example, I got an Asus P6T7 WS watercooled with an Koolance 360 and if I don't connect the stock intel fan cooler then my P6T7 refuses to POST... I don't remember if it show me a message before powering down though...

 

Also, check if your mobo's manual to see if it has some small diag leds (one for cpu and one for vga and sometimes one for ram) that may give you a clue if one of those components are faulty

Good points above. DIAG LEDS can help big time and a stand off under the board where it shouldn't be is worth checking out. Make sure fans are connected to the proper headers, particularly CPU.

 

After closely looking at the Manufacturers site you are correct the original release should support that CPU.

 

If you do RMA I strongly recommend Asus if you want less trouble.

 

Hope you get it sorted.

Thanks all. My issue is that nothing powers up!!

 

PSU fan doesnt spin. CPU fans spins gently. GPU doesnt spin at all. Front and back case fans twitch.

 

Will RMA and see what they say. I really hope its not the cpu either DOA or I broke it on installing it....it did make a weird noise when pushing the plate down on it. The pins seem ok though.

My previous PC had a similar fate. I was cleaning the dust like so many times before, and then when I tried to turn it on, nothing, just the fans powered on. It was old and it was time to upgrade it anyway.

 

I'm certain the culprits were either gremlins, or an electrostatic discharge.

That slight wierd squeak when closing the retaining bracket on the cpu is normal. As long as you aligned the two notches it is unlikely you broke or bent any pins.

Would a lack of cooling paste or improperly installed heatsink cause it not to power up?

 

Extremely unlikely but for example if you do not have a heatsink installed at all it will flash heat and fail instantly. It should keep running though so that's not a factor.

 

How can I tell if its a motherboard or CPU error?

 

Elimination. If you've got a friend with the same socket motherboard have him test the CPU. If it works, it's the motherboard.

 

It wont post with just one ram stick and onboard GPU either. Tried the PSU again with my old system and that seems to work (after a 2 second delay)

 

Motherboard/CPU is the only thing remaining. Disconnect *all* internal cables (except the two power cables) from the motherboard including front USB, LEDs and switches and try the onboard power switch.

 

Did it start once and then nothing or does it twitch every time you press the button?

I tried without any other internal connections and the result was the same. Cpu fans spinning (at different speeds!) Case fans twitching. Nothing else happening. Disconnect the power and reconnect....same again.

u can test the power supply

1. Disconnect every cable from the power supply, but leave the mains connected.

2. Get a paperclip and bend it into a u shape.

3. On the large power connector (24pin) that goes to the motherboard

find a green cable with 1 black cables on either side.

4. Use the paperclip to short the green wire to one of the black ones.

5. If the power supply is working it will switch on and the fan will spin.

 

Thanks but I tried with my old mobo/cpu and it worked fine...

Things to try

1. reset the cmos. Instructions should be in the manual but it's usually moving a jumper for a few seconds and then moving it back. This puts the

CMOS memory to default

2. make sure the 24 pin connector is on the motherboard and the secondary power cable(4 pin?) is also plugged in.

3. Verify the reset and power plugs are correctly installed on the mobo.

4. Remove the CPU to make sure no pins are bent, then replace.

5. remove all drives and any other peripherals except for the video card. This includes the hard drive.

6. make sure all power connectors are plugged into the video card.

7. install a single stick of ram.

8. try to start. If it doesn't, power down and swap the ram stick for the other one and try again.

9 if it starts, shut down and install the other ram stick. Repeat, then do with each drive etc until all is running.

10. If it doesn't start, before RMA go to the manufacturers forums or FAQ's to check for common problems that might be causing the issue.

Good Luck

If you know someone nearby who can test the CPU you should let them have at it

 

Otherwise I think we've narrowed it down enough to RMA the motherboard. Did you touch anything grounded to get rid of static before handling the components?

I had the exact same problem with my computer when I built it. This power supply isnt modular, so I had a bunch of extra wires laying inside this damn thing. Anyways, comes to find out that the 8 pin (2x4 pin connector) power connectors near the north bridge werent plugged in all the way because the seats didnt match the board or the cables. So to fix that, I had to push those cables in nice and tight. Honestly, it sounds like you might even have a ground somewhere. What I would do is take the mobo out of the case, along with the psu. Put the mobo on its static bag, plug the psu up, mount the vga and monitor, and ground the power jumpers and turn it on outside the case. If you get the same thing, you just eliminated the ground, and/or a possibly defective case (and Ive had a few of those too).

Im afraid no one nearby at the moment to test the cpu. I have 2x4pin cpu cables from my psu but im pretty sure i plugged them in correctly.

 

Grrrrrr...I dont believe ive ever done a computer upgrade without problems.

I was pretty sure I plugged mine in correctly too. My roommate proved me wrong. :(

I am happy if I drag them outside to blow the dust out without unhooking something by accident (and not discoving it until after putting everything back together).;)

Are you sure the risers to screw the motherboard down are in the right place ?

I saw a system once were a guy had put a riser where one should not be ... didn't end well

One of my mates assembled his new computer without any of the bridge screws. That didn't end well either.
