PLEASE READ I NEED YOUR HELP!!!
Hello, I tried to build my computer...and i had everything conncted cpu(intel Pentium D W/fan), HDD, MOBO (abit fatal1ty) Graphics Card (ATI Radeon x1650pro 512mb) Power supply (500W) DVD ROM (samsung Spinpoint) i connected all them, then flicked the power supply. The Fans started going the the case lit up with the leds, but, the screen was blank and after 10 seconds the computer turned itself off. I disconnected all the components except the mobo, cpu, graphics card, powersupply. Then i turned on the powerunit and this time the bios menu came up, but after a few seconds the power went again. Iv checked all the wires countless amount of times but no luck. I badly need help. Wat could be the problem, is the motherboard Falty? |

oh not good dont turn it on again and check that there is nothing blocking the back of the mother board ( the metal case thing at the back of the mother board )
if its not that hen it may be that the motherboard is crossing over one of the pins that attach it to the back of the case and this means that you have to unscrew and lift it up to see it is. d-shark |

well you know where you plug in the mouse and keyboard and the USB ports at the back of the mother board well there is a shiney metal plate that covers the extra space... right still with me ... and then if one of the metal covers that align all the components sockets ( mouse, keyboard USB ports Ethernet ) is poking out the wrong way wand has gone inside the [ ethernet plug for example then that may be the problem., as it provides a quiker way to the electiricty to go round { short circut } ]
as for the other one the mother board is screwed onto the case via screws and they screw into little sockets on the case ... right ... and then if one of the sockets that you screw the screws into,is underneath the motherboard and this crosses the pins on the bottom that are the left over bits of solder used to fix the compontents down then this to may short circut the board and this is probalby why your computer turns of after a 10 seconds as to not short ciruit itself. d-shark RAM you didnt mention any ram in your first post and this to may also be an issue so get back soon, you got me wondering now... |

Unplug everything from the motherboard except the CPU, RAM and power to the motherboard.

Remove any sound-cards, modems, basically go right back to basics, you don't even need the hard drive plugged in. See how you get on, if it still turns itself off check the motherboard isn't shorting out on the case, remove the motherboard and test it on a bench if necessary. Other things to check are that you have definitely put the heat-sink and fan on the processor properly and if the PSU isn't new then try a new one. Failing all that get the motherboard swapped out for a new one also. My System: Hybr!d

Thanks for all the help!!
Well the problem for it not starting up was that the cpu fan wasnt in properly. Total Newbie mistake.. my bad BUT..... I have a new poblem when i start it up after about 30 mins the power goes. Im thinking it is the powersupply but i do have a 500W sorce i thought that wud b more than enough here are my specs Abit Fal1ty mobo Ati Radeon x1650pro 512mb Graphics Card Intle Pentium D 3.0 ghz 1gb pc4200 ram Is 500W enough to support that??? And i googled the Graphics card and that says it takes 450W of electricity..surely that couldnt b correct?? Cheers for any help... thanks D-shark for your help |

You may have cooked your processor.
Continually turning on a PC without the proper cooling is not good, CPUs are very sensitive. The theory is that not having the fan on has damaged it, although it works, after 30 Min's the core has warmed up to a point where it becomes unstable. Same advice, remove everything, even the graphics card and use the on-board graphics, see if it's any better. |
