Comp tries to turn on. No beep. MOBO LED on

Hi All,

I bought my computer about 2 years ago from IBUYPOWER. Never had any issues. Will post specs after the story. So i used to have a GTX 580 but upgraded to a single 680. Then this past weekend i received a second 680(exact same). I was trying to get the hardware in but was having some issues fitting it for some reason. I had to get up and leave for a minute but wanted to make sure i didnt screw anything up (hardware was still not installed). Before i left it i turned my PC on and it was fine. Came back to finish up and managed to fit it and plug in the power cables as well. When i turned my computer on nothing happened. It seems one of the fans tried to turn on but it just stopped immediatly. No beeps nothing except for 2 leds that turned on and stay on as long as its powered up.

So far what i tried to do is just make sure all my wires are in correctly... however everything seems to be in place and nothing seemed to have moved... I am unsure what is causing this.

My specs are:
HAF 932 case
12gb corsair ram
1000 watt PSU coolermaster rated bronze
currently installed GTX 680 from EVGA 4gb FTW
I7 980
MOBO guerilla G1(the leds showing up are the ones right below the ram sticks)

I do not have much build experience but i do no this computer has worked flawlessly prior to this.
If any more detail is needed please let me know.

Thanks!

 

Was the computer unplugged from the wall before installing this new card?

What happens if you uninstall the new card?

 

Unfortunately i was rushing and forgot to unplug it.. If i remove the old card i have the same issue

 

That's not good at all. Anytime the PSU is plugged into the wall and the master power switch on the back of the PSU is set to on (if the PSU has a master power switch - the ATX Form Factor Standard makes that optional), +5VDC is applied across many points on the motherboard. Sadly, you may have zapped your motherboard, the PSU, cards, the CPU, RAM - basically, anything that connects to the motherboard.

You need to start at the beginning now by ensuring the PSU is good. This is best done by swapping in a known good supply. You can use a PSU Tester but understand they are not conclusive because they don't test under a variety of proper loads, and they don't test for ripple or other anomalies.

And before powering up with the new supply, I would disconnect all drives and remove all but one stick of RAM. And be sure to take the necessary ESD prevention cautions to prevent static in your body from zapping anything else. This is best done by touching bare metal of the case interior before reaching in and touching anything else. And of course, you MUST always unplug from the wall before installing or removing any hardware (with the exception of "external" USB and eSATA devices).

 

Damn... If it was all zapped though would anything even try to turn on though? It seems as if the fans and such try to spin for half a second and some mobo lights turn on.

Going to try testing to see what works. Unfortunately im at work most of the day so its difficult to find time.

 

It depends on what was zapped. I noted the worst case scenario - not "all" might have been damaged.

The PSU is required to output +12VDC, +5VDC, and +3.3VDC. Fans and drive motors typically run off 12V. The lights on the motherboard likely indicate 5 but maybe 3.3V. You need to check your motherboard manual to see what they indicate, and what it means that only "some" are lit. Depending on the board, the lit and unlit lights might indicate a code pointing to the specific fault. This will be spelled out in your manual.

What often happens when you first power up is the system checks for good power (called Power Good) and if not good, the PSU immediately shuts down to prevent further damage. I suspect that is what is happening here.
