Power up problem

I built a new system two weeks a ago. Its been working perfectly until yesterday. Every time I want to power up the computer, I turn on the surge protector, and push the start button. The four led lighted fans begin to come on for about a half a second, but then stop. Four seconds later, on for a half a second, then stop again. It will keep this up indefinitely if I let it. If I turn the power of, either at the surge protector or the power supply IMMEDIATELY after one of its 'shut-offs', four seconds later, it tries the half second start again, fails, and remains off. Leaving the power supply and/or the surge protector off for a few seconds sometimes will get me past this; however, it seems to be taking more attempts each time that I do it.

I am not a computer tech! I don't know how to test the components. This is the third computer that I have built, and the first problem I have had. Because the computer keeps trying to come back on at specific intervals, even after the power has been shut off, I'm guessing that the problem is in the mother board. It seems to me that that's the only component that has the capability to and would 'store' some/enough power to be able to attempt another start-up. I only have a bout ten days left to exchange any parts with Newegg. Any one else have any thoughts? Sure would appreciate it.

The first thing I would do is try resetting the cmos by removing the cmos battery. The procedure is to remove power from power supply, remove cmos battery, press the power button on the case a few times to discharge any remaining power, then wait a minute or two and then reconnect everything and try booting up. If it still don't work correctly, build your system outside of the case to rule out motherboard grounding to the case. If it still does it, then switch out the psu.
 
Did you install the correct amount of brass risers into the case? If not, your system is shorting out and shutting off. Try building the system together outside of the case, on the motherboard box or something.
 
Okay, to check out the PSU, I hooked it up to my 'outgoing' computer. It started several times over a three to four hour period and didn't cause any problems. I hooked it back up to the new build. I cleared the CMOS, as instructed. It booted up fine several times the rest of the yesterday.

First time the morning, its at it again; initial boot for half a second, 4 second pause, then repeat cycle, doing it once after power has been disconnected.

Now, for these 'brass risers'. Here is where you learn how much of a novice I am at this. I've done three builds over 4 years now, and I don't have a clue as to what risers you are referring to. I seem to recall some brass looking 'washers'. I believe that you are saying that I should have used them at the mounting points? I'll try to build the system on the motherboard box if I can to see how that goes, but I just reread the installation manual and it doesn't mention any brass risers. If you wouldn't mind, please clarify their usage.

Thanks again for the advise.
 
These would be the brass standoffs.

They get screwed down to the case and then the motherboard gets screwed onto them. If you didn't use them, then its most likely shorting against the case.
 
Okay, Those I have in place, and the entire motherboard is bolted to them. I just took a look through everything that came with this case and motherboard, and the only thing that I have that might be of help (that I can guess at) is I have 5 small red washers made of plastic, I believe. I could use these under the brass risers. ??
 
Not needed. You may have to take it in and pay a diagnosing fee to find out what is wrong so you can get it rma'd through newegg. Could be cracked motherboard, loose connections. hard telling.
 
I would still try building the system outside of the case to eliminate any shorting issues before going any further. It's your duty to make 100% sure before you go claiming bad hardware, if you don't, you will get burnt and look stupid, as I have in the past :o
 
Thanks for the advice linkin. I did receive an email answer from Asrock. Their response:

Please try the steps below:



o Remove the mainboard from inside computer to outside. You can place the mainboard on empty mainboard box

o Things to connect on mainboard is CPU, CPU cooler, video card, 1 HD (with O/S), and 1 memory module only system header (PW switch, reset switch)

o once you have barebones system setup go to the bios, and load the default setting by press F9 and save exit out the bios.

o Try to duplicate the problem you had before.

o Keep us update see if the type of set up resolve your restart issue. If problem resolve please insert the hardware back one by one.



Its been a long day here. I'll try tomorrow.:)
 
Just to keep you guys posted to see what in the world is happening (if anyone cares), here is what I just sent back to Asrock:

Completed bare-bones rebuild outside of case as instructed. Problem was duplicated on first attempt at start-up. After several power disconnects and reattempts, power up reached Asrock bootup screen. Went into BIOS, loaded default settings, saved and exited BIOS. Power-up successfully achieved three times after successfully shutting down computer. Fourth attempt to power up, duplicated problem. Disconnected power six times to get to a good power up again.

Powered down system and tried swapping out different components. Different memory card duplicated problem on second attempt. Different HDD (w/ OS installed) duplicated problem on forth attempt. Rebuilt system back inside case with original equipment. Four power ups successfully achieved, then duplicated problem. Any other suggestions?
 
First of all, if you a used a hard drive that a operating system on it from a different computer then you will have problems with that drive being attached to the system as the boot device. or did you take a new drive and install windows on it?

You have to start changing out parts to diagnose what could be wrong. Have you changed out power supply or processor yet? What about loose or damaged data cables like sata cables or ide cables to cdrom drives?
 
Have you tried taking out the video card and just use the onboard. Try it and see if the problem goes away. If it does, you have either a bad card or your power supply is cutting out on you. I know you said you tried the P/S in another computer, but did it have the same spec. as this one or was it a lowerend computer?
 
johnb35, The swapped out hard drive I used was a third hard drive that I reformatted, installed on the computer as the primary before I did the rebuild, and loaded it with Linux Mint OS. I don't have another processor to change out with this one, but the PSU was the the very first thing I checked out before I even wrote to Asrock. (Several people have suggested the PSU, but the PSU is only made of electrical components, not electronics. I feel that with the rhythmic/cyclical 4 second reattempt to start up, it has to be something electronic.) All of the cables/connectors have been checked out also. I still have the problem. To me, its pretty obvious that I have a bad mobo. We'll see what Asrock says.
 
Strangehold, there is no onboard video on this mobo. And PSU was tried on a a little lower-speced system. There's only so much I can do. I build a new computer evry 2-3 years. I don't have a lot of spare parts. What I do have is almost archaic to my new system.
 
Just got this response from Asrock:

Hi,



Thanks for update. I believe there is something wrong with mainboard. Please contact the seller for replacement.

I'll get in touch with Newegg.
 
Interesting point, stranglehold. Are you saying that I should be able to get graphics through my Intel 2600K by simply connecting to the VGA/DVI or HDMI port? Asrock never said anything about that!?
