Newbie Needs Help
First time doing something remotely close to building my own computer, but I thought it might be fun.
I followed a guide on pcmech, I had cd-rom, hd, other front panel wires connected to motherboard, but when I turned on the computer, hit the power button nothing happened. CPU and fan where pre-installed by geeks.com. After reading a little on the net, I decided to test basic components. I removed everything and started over. I connected the power supply to my motherboard, CPU fan to motherboard power. I shorted JPANEL power-switch with a screw-driver and noticed the fan turn on for a very small amount of time. I then attempted to reconnect the front panel power switch to the motherboard. When I hit the power switch nothing happens. When remove the front panel connection power switch and short it using my screw driver, I notice the fan turn on again for a very short amount of time. I could not understand why shorting the mother board power plugs with my screw driver and connected my front panel power switch to my mother board, and then turn on the switch did not behave the same. I am going to remove all the parts from the case and attempt to put the basic parts together on my poker table. Any ideas of what I should do? Here is my setup. Thanks, 10-Bay ATX Window Computer Case - 480-watt power supply (pre-installed) - Power cord - Screw pack Biostar M7VIG 400 Socket A mATX Motherboard - AMD Sempron 2200+ Socket A CPU w/Heatsink and Fan - Drivers and Utilities CD - Application Pack CD - User's Manual - One (1) 40-pin, 80-wire IDE cable - One (1) floppy disk cable - I/O shield 256 MB 184-pin PC-3200 DDR RAM Western Digital 40 GB 3.5-Inch Hard Disk Drive Artec 52x24x52 CD-RW & 16x DVD-ROM IDE Drive - Nero Express/Power DVD CD - User's Manual - One (1) 40-pin, 80-wire IDE cable - Mounting screws PS/2 Keyboard, Mouse and Speaker Kit - PS/2 Keyboard - PS/2 Scroll Mouse - Two (2) Speakers - Driver on floppy diskette |

Out of Case Expirement
I removed my motherboard from case. I already have AMD CPU and fan installed on motherboard by geeks.com. CPU power connects to motherboard. Videocard is included with motherboard. I connect power supply to motherboard. I short out JPANEL powerswitch.
CPU fan comes on board for a short amount of time and then quits. I can do this repeataly, but some-time the fan doesn't start. Any ideas? |

Hi SirRaleigh
Sounds like a powerswitch problem. I don't think it's anything to do with that CPU or video card. Let me get the two scenarios right: #1: You connect the power supply to the motherboard. Shorting the JPANEL powerswitch causes the fan to come on and then quit. #2: You connect the power supply to the motherboard. Connect the front panel power switch. Turn on the switch and nothing happens. I think there could be something wrong with the power on circuitry on your motherboard or your power supply. You can try using another power supply and see what happens. This article can also help.  Quote:

Recap
#1: You connect the power supply to the motherboard. Shorting the JPANEL powerswitch causes the fan to come on and then quit.
-> Correct #2: You connect the power supply to the motherboard. Connect the front panel power switch. Turn on the switch and nothing happens. -> Correct I take my power-supply out from my motherboard, I take a paper-clip and short green-wire and black-wire. I turn on my power supply and the power supply fan appears to work exactly like my CPU fan when power is connected to the mobo. Does this mean my power supply is bogus or will the power supply fan turn off because it detects a short or what? . |

What brand is the power supply?
Make sure the heatsink is installed correctly...doesn't matter if someone at Geeks.com installed it, it could still be installed incorrectly. Make sure it doesn't look like this. The recessed part of the heatsink should be over the raised part of the heatsink. Cricket

Power supply
AG II
480W SATA ATX POWER SUPPLY. Not 100% sure what you mean about the power supply and it is kind of hard to tell. Your saying the top metal part shouldn't be touching the plastic bottom part. On the installation on mine I have a set of clips that goes through the middle of the heat sink and is cliped down to the bottom plasic piece connected to the mobo. It appears the metal heat sink is floating above the bottom plastic piece connected to mobo. Can send pics if want. |

Power supply
No, the power supply only have that one sticker on it saying it is AGII.
All the stuff I have looks very generic, which is what I would expect since it was all very cheap, wouldn't never attempt to build an expensive system yet. Case is called Phantom High Performance Gamers Case model 8868-B Black, made in china. |

Do you have another compatible power supply you can swap in to test with? That AGII power supply may be defective.

Hi SirRaleigh
I really think you should try with another power supply. Just get one and quickly re-try. |

Even if you aren't doing a high-end build, it is very benificial to upgrade the power supply. Depending on your graphics card, it looks like a 20-30 doller 250 Watt FSP or Sparklepower power supply from Newegg (or anywhere else) would be an excellent option for you.

If you paperclip the ATX connector and it doesn't keep running, the PSU is defective.

I bought a $12 power supply unit tester from Circuit City. I saw fancy ones on the net but I couldn't wait. I plugged the 20-pin connector from the mobo into the tester. The green light DID not come on the tester which means the PSU is hosed in some way.
I'm going to complain to geeks.com as I really don't think I did anything to cause the failure. Thanks for the paperclip trick. |

Thanks everyone.
PSU was hosed in some capacity. geeks.com shipped me another one and now I'm starting to rock and roll. I hook up everything, memory loads, and I get screen output. |
