Computer Shuts Down - KT333 Ultra Dragon Platinum

Discussion in 'Soyo' started by MaxwellMI@gmail.com, Oct 4, 2005.

    My computer shuts down unexpectedly from time to time.
    This has become more frequent.
    It tries to reboot but gets stuck in a reboot loop.

    I have both side panels off my case.
    I removed & cleaned the heat sink & fan.
    I noticed the thermal grease between the AMD Athlon XP 1500 is nearly
    gone.

    I'm assuming this must be a heat issue.
    The longer I let the computer rest,
    the longer I can use it without the unexpected shut down/restart.

    ==================================================================
    My Soyo Hardware Monitor gives these numbers (they vary a bit):

    CPU Temp - 122 F
    CPU Fan - 2519 RPM
    CHA Temp - 97 F
    CHA Fan - 0000 RPM - My case fan plugs won't fit on the MB connector so
    it plugs in elsewhere

    Voltage
    Vcore - 1.76V
    +3.3V - 3.24V
    +5V - 4.67V
    +12V - 11.96V
    DDR 2.47V
    AGP - 1.47V
    ==============================================================

    System Info:

    AMD Athlon XP 1500
    ATI 8500 All-in-Wonder
    PC2700 DDR-SDRAM 512MB
    2 internal Hard Drives
    Creative DVD Player
    Sony CD-RW

    could be a power supply failure, check that. what size it is, how
    old, is it on a line conditioner.

    The power supply is about 2 years old. It was a replacement meant to
    deal with this same problem at that time. The problem has returned.

    ** PLEASE NOTE: **
    My Soyo Hardware Monitor has been showing the AGP voltage in "Red
    Letters" at times when it spikes to 1.67v or even 1.77v before
    returning to 1.47-1.48v. I'm assuming the red letters mean this is a
    problem when it's at 1.67 or 1.77.

    Allied AL-A300ATZ (max 300 watts)

    Okay whenever I build a machine, I do it ONLY for friends so no
    commercial stuff, I use nothing below a 400 or even a 450 watt power
    supply. You might want to go get a 450 watt one and plug it in and see
    if the problem goes away. I find them at the local mom and pop
    computer store for around $25.00US new only.

    I just ordered a SeaSonic S12-430 power supply (430 watts). I wanted
    to order a brand that was AMD certified. I'll let everyone knows if
    that solves the problem.

    In the meantime, any other comments or suggestions would be
    appreciated.

    The power connector next to the AGP slot interests me. Based on
    reading the manual I'm assuming that only an AGP Pro card can make use
    of this. Since my voltage spikes are related to my AGP, I was tempted
    to plug in a 4 pin power rail and see if that helped.

    If you have the 4 pin connector included with the power supply, I have
    been told to always plug it in. If you don't need it then it won't do
    anything.

    My board has the ATX12v 4-Pin Connector next to the AGP slot as shown
    here - http://www.clubic.com/photo/00030441.jpg

    This is d.i.f.f.e.r.e.n.t than the 4-pin connector use on some MBs to
    give extra juice to the processor as shown here -
    http://www.atxpowersupplies.com/images/p4-connector-200x142.gif

    The User Manual lists the slot as "ATX12V 4-Pin(+12V) Connector". The
    manual also says the ATX12 4-Pin Connector is for AGP Pro use only. I
    also checked my BIOS and it appears no changed would be needed to
    activate this connector.

    Given that info and the availability of an extra rail from my power
    supply, do you still recommend plugging into the 4 pin next to my AGP
    slot?

    Problem appears to be solved.

    ** UPDATE **

    My new SeaSonic 430w power supply arrived three days ago. Not a single
    problem since installation. I've run the system hard (particularly the
    video card) trying to recreate a previously unavoidable problem. Based
    on 3 days of use, I think the power supply was my problem.

    Originally I was only using a 250w PS. Two years ago I upgraded to a
    300w. Now I've had to upgrade again to a 430w PS. I've very happy
    with the honeycomb ventilation, ample connectors, 20/24 pin option,
    cable management, etc. of the SeaSonic PS. I would recommend it to
    anyone who is willing to drop $100 on an ATX power supply.

    Thanks for your help.
