Ok about a year ago I built a new gaming rig. It worked perfectly up until the other day. Now when you press the power button it goes on for a second or two and then restarts. It doesnt even get to the WinXP boot up screen!!!! It just goes on and off...... Im thinking its the power supply but im not sure. What do you guys think? Here is a list of my computer components starting with the POWER SUPPLY
thanks for your help :pt1cable:

Can you get to the BIOS Or not, did you do anything to your computer recently (bios flash, new driver, new part, open it up and do some cable man, etc) and do go through shortstuffs checklist it will help, us eliminante stuff.

No it will NOT go to BIOS!!!! It just turns on and off before anything else happens. I just got a replacement powersupply so hopefully that is the issue
August 26, 2009 5:28:20 AM

Yeah, and check all your connections,

And I assume you didn't do anything to your comp?
August 27, 2009 1:32:58 AM

No I didnt do anything to the computer..... I didnt overclock it NOTHING and now I swapped out the powersupply and its doing the SAME THING!?!?!!?!?! Ideas? suggestions???? I also ripped out and tested the Ram sticks one at a time and that didnt do ***..... Now im starting to think its the motherboard or the CPU either of which is going to be a bitch to swap......

Is the CPU fan working when it goes on ? Sometimes if the fan goes out the CPU will overheat and shut down, but it should run for a few before it gets to hot.

Do that check list Shortstuff said



August 27, 2009 3:01:00 AM

yea the fan on the CPU starts as normal.... that was one thing I already checked
August 27, 2009 3:13:17 AM

Reset the CMOS, using a jumper, ( if there is no jumper I think you can just remove the battery), if you havn't already done that.

Unplug and plug in all connections power, data, etc.. (again if you havn't already done it)

If you have a spare graphic card, cpu, or even mobo try stuff out with that.

Did anything change with the new powersupply?
August 28, 2009 2:46:29 AM

nothing changed with the new PSU. Do you think the mobo + cpu are still under warranty? I purchased them from www.newegg.com a little less than a year ago RETAIL not OEM
August 28, 2009 4:08:06 AM

They wouldn't be under warranty from newegg, that usually only lasts 30days unless you purchased an extended warranty. You'd have to check with intel and gigabyte.
September 1, 2009 12:21:32 AM

So now im trying to eliminate the possible culprits... obviously the case is not causing this, its not the hard drive because if it was a crash I would get an error on boot up, I dont think its the video card because again even if the card went bad that wouldnt make the pc turn on and off, It cant be a bad ram module because I tried them one at a time in the correct slot... I installed a new PSU and that was clearly not the issue ...im thinking its either A:motherboard or B:CPU ......what do you guys think?

It sounds like a possible short. Did you build the system outside the case with the motherboard on a non-conductive surface?
September 1, 2009 1:01:43 AM

yea I built it with a guy who has been in the IT field for 20+ years

September 1, 2009 1:51:49 AM

That doesn't rule out a possible short. Even the most experienced builders occasionally make mistakes.
September 1, 2009 2:23:37 AM

so what would you do at this point? I have no way to determine if its the mobo or cpu.... or both

September 1, 2009 2:48:23 AM

I already told you what I would do. I would rule out a short before you start replacing parts.

Does the monitor turn off or does the PC complety shut off ? all HDD lights power lights ect ?

I just went be my nephews house and when he turned on the pc the monitor would come on and then see the power saver mode then the monitor would go off.

but the lights on the HDD and power button was still on.

I changed the DVI on the back of the GPU unpluged all USB items set bios to optimal defaults and it worked

shurgs maybe this will help

=1 also take it all apart and put it back together again checking to make sure all is tights no screws left in the case ect

September 1, 2009 3:00:22 PM

Swap out the motherboard with gigabyte, easy customer service, just call them and give them your model...
a b B Homebuilt system
September 1, 2009 5:08:36 PM

Do what shortstuff said. Also, check to make sure the CMOS battery is NOT dead.
September 2, 2009 3:58:25 AM

The monitor is fine, Im using it right now with a second PC. Basically what happens is I press the Power button on the tower.... all the fancy lights turn on for less than 5 seconds and then it turns off and starts the cycle over and over :( 
September 2, 2009 9:25:57 PM

as far as the CMOS battery being dead....... I dont think thats the case, even if the battery was dead the PC wouldnt turn on and off after a few seconds.... or am I missing something here?
a b B Homebuilt system
September 2, 2009 10:58:23 PM

^Yes, it can if the battery is dead/dying. I'v seen it happen.
September 4, 2009 12:41:20 AM

Ok but the motherboard is maybe a year old tops.... I wouldnt think the CMOS battery would go dead after that short amount of time
September 5, 2009 1:39:34 PM

anyway the last time I started the computer it stated something about repairing the BIOS, went black and has not turned on since. Does this sound like a motherboard issue?
September 6, 2009 5:35:53 PM

yes, it does, what did you do, when it stated that. Try replacing the battery, reseting the CMOS, everything to do with that.
September 7, 2009 1:15:42 AM

I didnt do anything besides turn the PC on. There is no jumper on the CMOS so how the hell do I reset it?
September 7, 2009 2:17:53 AM

You need to pull out the CMOS battery for about 30 seconds and put it back in, this should reset all your BIOS settings.
September 7, 2009 7:07:30 PM

Ok so I pulled out the battery for 30 seconds, put it back in and attempted to start the computer - same results
September 8, 2009 1:45:07 AM

Now im just straight up pissed. I stripped my entire pc down and am going to send that motherboard back to the cocks at Gigabyte..... Nothing but problems with that board since install and I dont really feel like troubleshooting it for the next couple weeks.... they made it, they can fix da bitch
September 8, 2009 7:19:37 PM

From what you have provided, it sounds like a hosed BIOS. Which is doubly strange since that board has the dual BIOS feature. All I can think of is something wiped out the original BIOS and your machine fell to using the backup, and then something hosed the backup. If you can get no joy from dealing with Gigabyte (they can usually send a new replacement BIOS) and they are unwilling to repair under warranty (this part most likely only has a 90 day warranty) then you are stuck with the option of replacing the motherboard. Personally speaking, I would just replace the motherboard and call it a day. My time is worth way too much for me to screw around with something for more than a couple hours before I replace it and call it done.
September 8, 2009 9:06:26 PM

well thats an excellent point Houdsteeth however I already contacted Gigabyte and they stated the MOBO was under warranty for three years after manufacture date ...so im wrapping this bitch up and sending it back to them... it was a $200 mobo less than a year ago and im not just going to suck up the loss without having them look at it first.. In the future I will be going with Asus or MSI boards
September 8, 2009 9:56:33 PM

"My time is worth way too much for me to screw around with something for more than a couple hours before I replace it and call it done" Thank you, well said Houndsteeth. And he's right, as were several others on the forum. If you can't even get to the BIOS, then the problem resides with the motherboard (specifically the BIOS). Just buy a new motherboard (from a different manufacturer) and call it a night.
September 11, 2009 2:47:41 AM

so I talked to the folks at Gigabyte and they told me it would take 3 weeks for them to test the mobo....... so until then im screwed
