    Hi everyone, I recently built a PC and everything worked great on the computer for several weeks and then one day the system would no longer start up. I think the system is not POST'ing because when you hit the power button, everything powers on, fans are going, etc... but the system does not beep and the monitor stays on standby mode because it doesn't seem to be getting a signal. I opened the system up and made sure everything was still seated securely, along with checking all plugs in the back to make sure everything was connected. I still had no luck so I reset the motherboard by taking out the battery and moving the jumper over to the clear position as instructed by the manual. After clearing the BIOS, it still would not start.

    I believe I have a problem with the motherboard since it doesn't seem to POST but I'm at a loss as to what the problem could be. Any help is sincerely appreciated! The system specs are as follows:

    Asus M2N-E AM2 NVIDIA nForce 570 Ultra MCP ATX AMD Motherboard
    AMD Athlon 64 X2 4000+ Brisbane 2.1GHz Socket AM2 65W Dual-Core Processor
    Asus 20x DVD+R DVD Burner DRW-2014L1T
    Seagate Barracuda 7200.10 ST3250410AS 250gig SATA HDD
    Creative Sound Blaster X-Fi XtremeGamer 7.1 Channels PCI Sound Card
    Crucial Ballistix 2GB (2 x 1GB) 240-pin DDR2 SDRAM DDR2 800 (PC2 6400)
    XFX PVT84JUDD3 GeForce 8600GT XXX 256MB 128bit GDDR3 PCI Express x16
    Antec Mid-Tower Computer Case w/380W Power Supply
    Microsoft Windows XP Home


    Thanks for your help!

    Well it sounds like you have enough power to run if everthing is spooling up.

    Try putting your ear close to the hard drive while it's booting up. And around a minute into it, see if you can hear the drive go into rapid seeks while it loads windows.

    If it's doing that, then I would guess the graphics are the problem.
    Try another graphics card if you can get your hands on one.

    You might try to pull out one stick at a time of memory to see if you got a bad one, but I doubt if that's the problem.

    And yeah, it could be the motherboard.

    I look at your component list and it makes me chuckle.

    could be psu, could be mobo, could be other things, but start with psu/mobo.

    Aside from the SoundBlaster and weak PSU, those are fairly solid components.

    Start with just mobo, CPU, video, and 1 stick of RAM. If it boots, start adding everything else piece by piece until it fails. If it doesn't boot, try the other stick of RAM, or swap out the video card/psu if you can get your hands on another.

    do the usual bare minimum config troubleshooting.
    take out sound card and drives. keep mobo, cpu/heatsink, 1 stick of ram, psu, and vid card (optional) only.
    if still won't post, try the other stick of ram or a known working ram.
    work your way to the other components till it posts.

    edit: didn't see shroomie's post when I submitted this reply :o

    Thanks for your help guys, also... this build is for a friend on a budget so I realize some of the parts aren't the best but he didn't need a completely decked out system. Thanks again... I'll try this when I get home.

    even if he didn't want a "completely decked out system" you can still buy decent components.

    except for the weak power supply, and the AMD CPU, the components seem fine to me.

    My first guess would be power supply. 380W is quite weak.

    As has already been said, disconnect EVERY component from the motherboard and power. Leave just the CPU, a single stick of ram, and the video card in. Try after that.

    Also, check to ensure that the direct-to-CPU power is attached (easy to overlook if you aren't familiar with building desktops) and also that the power to the video card is plugged in
