Hi, first time user here. I recently ordered all parts (so they are new) for my new computer to build for myself. I put the motherboard in, correctly installed everything and connected the PSU to everything that needs power. What I found was odd was the stand-by power LED that is located on the motherboard just blinks with about 2-3 seconds in-between each blink.
I had ordered an ASUS Sabertooth X58 motherboard from Newegg.com about a month ago and it turned out to be defective. I had it RMA'd and just today I received the new one.
I have tried to unplug all unnecessary things from the PSU (such as fans and HDD), and only used 1 RAM stick, and didn't even have the GPU 6-pin plugged in, just to try to get the motherboard to turn on.
I had read a post on Tom's Hardware about a recent problem someone had that was similar to mine. His stand-by power LED was blinking and how he got it to work was he unplugged his front panel USB ports. I unplugged mine and it still doesn't work. =/
My system specs are as follows:
Intel i7 950 CPU
ASUS Sabertooth X58 Motherboard
6GB Corsair DDR3 XMS RAM (2x3) @ 1600mHz
Thermaltake TR2 600W PSU
Nvidia geForce GTS250 (1gb) GPU (from old computer)
Western Digital 320GB Hard Drive (from my old computer)
Thanks in advance for all the help; I just can't seem to get this to work.
Check around on the site for a sticky on trouble shooting new builds. It will cover things like resetting the CMOS for BIOS back to defaults and other such steps.
Can you do that without even turning on the motherboard? The standby light just blinks and doesn't allow me to power my computer up.
Although everything is properly connected to the motherboard, when I push the power button (which is connected properly) in the front of the tower, the PSU doesn't even "turn on." I have tested two power supplies and neither are defective.
What is the brand and model of the other power supply you tried? Is is a known good supply that was power a modern system?
Sorry, this is tough when things won't even power up.....we'll use the process of elimination.
UN-plug the power supply from the wall........... (or turn off with the switch on the back of the supply)
Then WAIT until the GREEN LED on the motherboard goes Off.....
STEP #1 : Now...
- remove ALL the RAM sticks
- remove all SATA cable completely from the system (yup pull 'em out and set them across the room...)
- unplug all the hard drives, DVD drives, and floppy(hey ya might have one... ) from the power supply
- unplug all fans from the motherboard
- unplug the 4+4-Pin ATX 12V from the CPU, yes, unplug it too
- unplug all the front panel switches
- unplug all front panel USB cables
- unplug the front panel audio cable
- unplug your mouse, keyboard, or any thing else you have connected to a USB port
There should be no wires, cables, or devices of ANY kind connected to the motherboard...............
The ONLY cable from the power supply that should be connected to ANYTHING is;
- the 24 pin cable to the motherboard
Turn the supply back on....
If the GREEN LED on the motherboard still blinks:
- its the CPU
- or the motherboard
- or the power supply (SO, try Both of the power supplies you have now...)
STEP #2 (If the GREEN LED on the motherboard still blinks)
Next step would be remove the power supply and motherboard from the case. Set them on a non-conductive surface, like card board. Connect just the 24 pin cable again. See if the LED blinks when the supply is turned on. (some times the metal stand off's or the screws holding down the motherboard to those stand off's cause a short circuit. Sitting out side the case on card board we've eliminated that possibility)
STEP #3 (If the GREEN LED on the motherboard still blinks)
Remove the CPU from the motherboard....
Turn on the power
STEP # 4 (If the GREEN LED on the motherboard still blinks)
The motherboard is bad....
Or, you just have two (2) bad power supplies....
The GREEN LED is powered by the 5 VSB power. That LED should not blink if the voltage remains on and steady. Were trying to find out if something is pulling that voltage down (or shorting it out...)
I have everything connected and my new computer turns on... YAY.
Now, when I turn it on, it displays the typical information on my monitor and what happens is it will go to the OS boot-up screen. This is the screen where it says "Loading Windows" or something along the lines of that, and 4 orbs of different colors come together to form the windows "flag" logo. Once the 4 orbs form, and they begin to shine brightly, my computer just restarts and goes back to where it'll tell you how to go into the BIOS.
That happens when you try to "reuse" the Win7 already loaded on to an old hard drive from another system....
You need to break out the Win7 DVD and reload a clean copy of the OS onto the hard drive. This is so all right piece of software, drivers & such, that MATCH your new hardware are loaded....
When you install do NOT input the Key to Register the OS.....you can run just fine for 30 days like this (some times I have to load & reload to get things right, and you don't want it Registered until your sure your done...)
