12/12   My computer just died. Power switch does nothing. Is it most likely
        the MB/CPU or power supply?
        \_ Disconnect the MB from the PS.  Try to turn it on.  If your drives
           do not spin up, it means the PS is faulty.  The MB could still have
           a problem, though.
           \_ how can you disconnect the PS from the MB and test it without
              buying a special ATX PS tester?  isn't an ATX PS dependent on
              the motherboard to turn it on?
              \_ Right.  Sorry, was thinking of the old AT days.
           \_ I think what the above person is saying is:
              Switch -> Motherboard -> Power supply
              If you remove motherboard from loop, you can't turn on power.
              Anyway, I would have a known good power supply and swap that in
              to distinguish between motherboard / power supply problem.

5/27    I just spend a few hours on a silly BIOS problem and I'm posting it
        here so that you guys wouldn't have to go through this again. My
        MB is Gigabyte GA-7N400 Pro and the latest BIOS update is version
        F17, which is in 2004. It comes with the MB Sil (Silicon Image)
        3112A SATA controller, which unfortunately, is outdated from 2002
        and does not recognize my Seagate 750G drive-- the boot loader

8/9     I had a motherboard die after like 90% of the capacitors leaked.
        Appareantly this is a widespread problem (badcaps.net). I'm
        wondering, (a) why I hadn't heard of this earlier, and (b) why
        there hasn't been a big recall of defective components.
        \_ (a) because you don't read /., http://theinquirer.net, ....  Do you
               read anything?  Try to keep up a little, will ya?  This is

2/13    Buying 1GB PC3200 DDR memory for my G5-- any suggestions? I'm leary
        of the top 5 returns from pricewatch....
        \_ on a G5 make sure you get good memory and not some generic
           PW crap. I'd check Kingston to find out what sort of timing
           and stuff they'd put on their branded Mac compatible RAM and
           then go w/ a generic maker that matches those specs (or

1/17    My DMA is in fact turned on, but I'm hardly getting the 133 rate
        in my ATA133 as claimed by my motherboard and hard-drive. What
        are some culprits in the lack of performance? ok thx.
        \_ How are you measuring the throughput?
        \_ You know nothing can sustain ATA133 throughput, right?
        \_ And you're running which OS?

12/7    Followup to the hardware problem yesterday:  I down-clocked the
        FSB to 100MHz and the problem went away.  The memory went from 266->200
        the CPU went from 1466->1100, but the AGP and PCI stayed at 33MHz.
        Since memtest showed the memory itself is probably OK, and GIMPS showed
        no CPU problem, that says to me the AMD 761 Northbridge is the problem.
        Thanks to everyone who helped with this tricky problem.

12/6    I'm at my wit's end with a problem.  I'm running WinXP and a lot of
        newer 3D games make the machine randomly lock hard.  There isn't much
        pattern to it, but some games do it and some don't.  This problem is
        not mentioned under tech support for the games besides the generic
        "Update your drivers and DirectX" which I've done.  Games which crash
        include Railroad Tycoon 3, Rome:Total War and Sid Meier's Pirates, and

9/2     If i buy a MotherBoard with 2 SATA ports, does that mean I can only
        have 2 SATA devices attached or is there some chaining possible?
        \_ Only 2 SATA drives, although your MB probably has 2 ATA connectors
           too for optical drives and the like.

1/19    Anyone tried to build a Athlon 64 based system?  What motherboard
        did you use?  Any incompatibility problems?
        \_ I started to spec it out and then found out that AMD was
           going to switch socket types in Q2 2k4 and gave up the
           idea. We have a couple of dual opteron boxes at work (newisys)
           they are very nice. No problems with Linux (SuSE Enterprise

9/16    I got a used (free) computer, but I've realized that it locks up.
        I've swapped out the RAM, Mobo, power supply and disk. It still
        crashes.  (isn't really free, huh). The last time it was a seg
        fault in the /etc/init.d/umountfs while shutting down. The errors
        seems to be random, but possibly occur slightly more in the AM
        wee-hours. So the last thing to swap out is the CPU.  It's an

6/18    I want to buy a cheap reliable server.  It doesn't need to be fancy.
        It doesn't need to be blazingly fast (though it would be nice if it
        was.)  It doesn't need insane amounts of disk or anything.  What I
        want is it to be reliable and for it not to cost too much.  Anyone
        have a good recomendation?  Would I be stupid to go with dell or
        someone like that?

10/18   I'm looking to buy some new hardware to run Linux on: AMD Athlon,
        AGP graphics for X. Any suggestions for the motherboard, chipset
        and graphics card. I don't really need 3d but wouldn't mind having it,
        if it doesn't degrade 2d performance.
