*** ME!!!! Help me with my homebuilt system!!!

[Madhatter4]

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

Going through every step in this checklist is the first place to start with troubleshooting your problem.

http://www.tomshardware.com/forum/261145-31-read-posting-boot-problems

I would try booting with each stick of RAM by itself in the first RAM slot first.

 

[tkgclimb]

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.

 

[Madhatter4]

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

 

[tkgclimb]

Yeah, and check all your connections,

And I assume you didn't do anything to your comp?

 

[Madhatter4]

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

 

[Madhatter4]

yea the fan on the CPU starts as normal.... that was one thing I already checked

 

[tkgclimb]

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?

 

[Madhatter4]

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

 

[tkgclimb]

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.

 

[Madhatter4]

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?

 

[shortstuff_mt]

It sounds like a possible short. Did you build the system outside the case with the motherboard on a non-conductive surface?

 

[Madhatter4]

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

 

[shortstuff_mt]

That doesn't rule out a possible short. Even the most experienced builders occasionally make mistakes.

 

[Madhatter4]

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

 

[shortstuff_mt]

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

 

[Niklas_13]

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

 

[Niklas_13]

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

=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

 

[pluke the 2]

Swap out the motherboard with gigabyte, easy customer service, just call them and give them your model...

 

[Shadow703793]

Do what shortstuff said. Also, check to make sure the CMOS battery is NOT dead.

 

[Madhatter4]

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

 

[Madhatter4]

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?

 

[Shadow703793]

^Yes, it can if the battery is dead/dying. I'v seen it happen.

 

[Madhatter4]

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
