No Power to Computer

I put together a computer upgrade after several years- however, when I got to the crowning moment, the computer won't turn on. Here are the things I do know and everything carried over was working in the 2 minutes before I turned the old system off for the last time:

1: The graphics card is carried over (Sapphire 7970)
2: The RAM is carried over (G.Skill Ripjaws)
3: Sound Card is carried over (xFi Fatality)
4: Blu-ray drive is carried over
5: SSD hard drive is carried over (Intel G2)
6: PSU is carried over (660 Platinum Seasonic)

New hardware:

1: Asus Gryphon Z97
2: Intel i5 4440
3: case (Silverstone PS07)

Everything is plugged it and rechecked over twice. The i/o connectors were looked over three times (particularly the power switch one). I hit the power switch, no power to system. Where did I go wrong? Thanks in advance!

6: PSU is carried over (660 Platinum Seasonic) first one to check
test with a jumper wire on the 20 pins atx plug. the green and black right beside each other. but don't forget to unplug all but the fan.and see if come on.

Before I get to that, there's something I forgot to mention:

The back of my sound card has a Red LED light that's on. I didn't see any LEDs on the motherboard- (don't know if this motherboard has any).

Thanks for your quick reply!

I just went to Youtube to see how people do this and then I look at my equivalent connector and see that all the wires are black. How do I go about doing this?

UPDATE: Just put the PSU into another computer and it works.

UPDATE2: Plugged in a cheapy spare PSU I had and it powers on. Does that definitively mean that my SeaSonic 660 is dead?

Thanks!

check that u don't have an extra standoff shorting the mobo to earth..yeah i know ..but check it happens so often as you cannot see the standoff until u lift the board...

Never use a stand off for a screw hole that does not have the copper metal around the hole. If it is just fiberglass then do not use that hole no matter what.

Okay, did a pile of stuff, replaced the PSU and the system powers.... sometimes. Sometimes when I hit the power switch, it will work fine. Other times (more often than not) I hit the power switch and the CPU LED stays red and I see no signal to monitor. I swapped my graphics card for a spare graphics card and the same thing happens. However, when I unplug the graphics card and use onboard, it works every time.

New PSU is a Corsair RM 650. Running a Silverstone PS07b case with the default standoff setup. I didn't see any excess standoffs, and checked some youtube videos with people installing a microATX into this case to confirm and see they only added a standoff and not remove any.

Glad to hear it's working to some degree.

A few thoughts:
1. There are a few BIOS updates for improved system stability, so you may want to try flashing your BIOS to the latest.
2. Which PCI-Express slot are you using for the video card? Have you tried any other slot to verify results?
3. Is the graphics power connector in good condition? Is it being used on both cards? If so, it does seem to be a factor for both situations that are showing issues.

Congrats on the progress thus far. Let's see if we can drive it home!

when you have the machine running off of the onboard video..first go into the bios section that allows you to change from onbord to pcie video .u must set this to external card and dissable or (auto) mem for the onboard video...next and have the video card ready to be installed ..swicth of and install the card.. switch it on and run the screen of the card the next boot........i agree with Mr k..as new bios updates are for that reason..generally to improve system stability..your new supply should be up to the job....

Just woke up and system would not power on again until I yanked the displayport cable and replugged. (worked after one time but some times it'll be stubborn). Also remembered that I never found any switch to turn off the onboard video in the BIOS. Is there a way to do that and is that a reason as to why I'm getting all these symptoms?

Thanks again everyone!

So, is the cable the possible issue here? Do you have other options for your monitor? I would try DVI/VGA, for example.

The Intel graphics option is configurable in the System Agent Configuration section of the BIOS, but I don't think you should have to mess with this. You can, but the board should output to whichever output is connected to a display.

Just wrapped up trying a pile of stuff:

1: moved graphics card into a different PCI-E slot: same problems
2: unplugged everything and replugged everything: same problems

Observations:

1: turning on the system without doing anything will result in the CPU_LED light staying a solid red and thus not POSTing
2: unplugging the displayport cable and replugging it in will allow the system to POST - this has to be done every single time the computer has been turned off - tried with spare graphics card, same thing
3: any time the system can turn on and the display comes on, everything works just fine
4: there's a pretty loud double click while booting up. I'll see the "Starting Windows" screen for like half a second and then the double click comes. Right after is the blue Welcome screen for another half second and then Windows comes on (7).
5: shutting down results in another fairly loud click when the power goes off.

Here's hoping I don't have any defective parts, but getting prepared for just about anything.

Thanks and hoping everyone's having a happier new year than being stuck here with a sometimes working system.

I've swapped displayport cables once and tried HDMI as part of this morning's testing. No luck.

um ok brain is sort of awake..lol..unplug your hdd optical and remove any other cards you have in the machine..i wont you to start as well just what is necessary for the machine to run..also re check you cpu cooler is it mating correctly..and as for that clicking sound..?? ponders....so basically mobo ram cpu cooler video card and key board ..does it boot up now you have not listed what cooler u r using...sata hdd cables often fail..as to y this is i dont know but they do.try new cables for your hdd as well.. the clicking sound have you got maybe a cable that is pertruding into a fan..?? and it it hitting the blades of the fan ..

down load this pleas and install it if you can http://www.alcpu.com/CoreTemp/ not to dispair you but i am thinking mobo sorry prolly u dont want to hear this but if all the other components are fine in other system`s known to be good and working.. it seems odd you cannot get anything to run in the pcie bus lanes..it could be cpu ..but aside from this..it could also be incorrect bios settings...

Core Temp reports:

All cores are 30C to 34C. Min is 29C on cores 1-3 and 32C on core 0. Max is 36/38/33/37. Load does from 0-3%.

The weird thing is the computer works just fine after doing that cable pulling and replugging dance. No crashes, no hangs, no BSOD, no screwed up graphics or anything. Games run just fine and besides that one detail about starting up after shutting down, nothing is suspicious. Typing on the system right now. This is with the 7970 in the main PCIe slot.

I did find it odd that the Silverstone case I got doesn't come with a speaker jumper thus I can't get any error message beeps. Looked all over the manual (PS07b) and there's no mention of one either.

ok install and run this pls http://www.majorgeeks.com/files/details/intelburntest.html this will determine if your system is stable as for a pc speaker these days it seems that they don’t come with them in the cases..you can get a small speaker your self an attach it your self..um your local electronic shop or even a computer shop may have them..generally after market coolers are the best bet..i often find what is supplied with the cpu..is just like there so they can justify that it came with one ad thus covers them if in fact something may fault..............what i do is strip down a cheap pair of headphones 5$ specials and remove a speaker strip out a pair of leads from an old case with the little connector pins and solder the leads to the speaker and attach other ends to the mobo...

i have 2 main machines..my linux box and my win box..when i built my win box i ran the stock cooler only to find temp`s were extremely well quite high..so i went liquid cooling..i have never looked back..there is much controversy about liquid vs air..both my machines now have liquid cooling..

Glad it's working. Let's hope it stays that way. I haven't seen a case with a speaker in many years. This has usually been a motherboard part.

No crashes since, all that leaves is this cable pulling and replugging (displayport) before the system would power on. Otherwise CPU_LED stays solid red. Any ideas on why that happens?

ok i am looking at your mobo manual..that cpu led is a problem..indicating that there is infact a cpu issue..to what exactly i am yet to find out...it may be heat..look at page 1-27 of your manual..is this jumper set to default..also can you pls set all jumpers back to defaults and go into bios and choose the option ...setup-defaults.set to that ..exit bios and see if it bootsbut before exiting bios make shure u change the pcie card setting ..to the pcie enable...
