Sandy Bridge new build - NO POWER

post #1 of 9
Thread Starter 
Hi,

I am building a new pc with the following configuration. When I turn the pc on, there is absolutely no response. The only light I see is the Motherboard standby LED. I don't see any CPU LED, fans, or not even the fans turn on. Any clue will he highly appreciated.

Intel Sandy Bridge 2600K
4 Kingston 4GB DIMM (1600Mhz, 1.65v)
ASUS P67 Sabertooth motherboard
eVGA GTX 560TI, 1GB
Coolermaster 922 HAF case
Cooler master GX 750W (80+ rating, +12V rail for up to 60A)
Corsair H60 CPU cooling
Western Digital 2TB SATA 6Gb/s data drive
OCZ 120GB SSD for OS and application

Initially I forgot to connect the 8 pin (12V) cables. At that time the CPU LED, the fans turned on. I then realized that I didn't connect the ATX 12V power. After connecting that cable, everything basically stopped. Now I get absolutely no response.

Thanks,

Azad

That's really quite odd mate. You've most likely done this, but disconnect all the plugs and reconnect them, ensuring that everything is seated correctly.

Hope you fix it soon!

First time I built my first rig, I didn't connect the case jumpers to the correct pins on the motherboard. I recommend you double check those.

Oh, I found what the problem was! The power switch cable got pulled off from the MB - Now the board powers up, the fans run, cpu led is on, BUT no video output!!

The GTX 560 Ti has 2 DVI and 1 mini HDMI. I have connected monitor in all three, but no sign of life!

[Solved] I figured out the problem. I had to hold the power switch more than 4 sec to cancel off the sleep mode. I got the motherboard to respond and now I am seeing the video -

Now let me go and explore.....

I came late but you'll learn one thing:

The problem is usually something you would never think of.. Just like my friend calls me and we are troubleshooting over phone... The PC restarts after 5 seconds. I ask him to swap rams all that...Turns out he forgot to plug power connectors to his GPU...

You are absolutely correct. Since I was moving the cables around, I never thought that the power sw switch in the system panel connector coule be loose.
