This is just an update to the previous posts. I ran Memtest86 on the
machine for over 9 hours, 9hrs, 6mins, to be precise, and again for 13hrs,
17 min; 0 errors in both cases, but in checking over the System Event logs,
which I hadn't checked very thoroughly before, I found that the application
errors were principally ones which accounted for the times the machine hung,
the CA EZ Armor AV True Vector Service was the culprit--only other app error
was WMP which I think was my daughter's doing when she tried to play her MP3
player through the machine. The system errors varied, predominantly seemed
to occur when the machine was at idle, when it would reboot itself, having
recovered from the error. There were a 3 or 4 8e errors, some 1a errors,
one 7e, a couple of 0a(s), a 20, and a couple of 55(s), identifying NTFS as
the complainant, but running chkdsk found no problems. I believe the 55s
came from when I flashed the BIOS and didn't catch the enabling of the PATA
RAID in the BIOS setup. Anyhow, they haven't repeated. The total time
frame is from the beginning of July to date, running a couple of hours most
days, say 5 out of seven.
This seemed to point (in light of the memtest run) to drivers, so I
tried, very inadvisedly, as it turned out, to use Driver Verifier. The
machine ran, very, very slowly for a while then blue screened with a
DRIVER_NOT_LESS_OR_EQUAL but when I tried to reboot the machine afterwards,
it ran as if in treacle, more slowly than my old 386SX with 8MB RAM ran Win
95, and this is an Athlon 64 2GHz machine with 1GB of memory. When I tried
to look at the results, Verifier informed me that I should add more physical
memory, since (some kind of) memory usage was at 60%. Worse by far is the
fact that now the machine runs that way all the time in normal mode, except
that it faults or hangs much more often. It runs about five times faster in
safe mode than in normal, in fact.
I haven't been able to see what is going on here; Process Explorer
doesn't show any abnormal (that I can tell) processes running; nothing looks
wrong in Device Manager, and I haven't figured out any other place to look.
I tried to do a System Restore, and it refused to do it for any of the
restore points (all reasonable ones, as far as I could tell) that I tried.
One other very strange occurrence that I'd not ordinarily mention, is
that I tried installing PC Wizard ver. 1.63 (
www.cpuid.com) as a system
inventory application (Aida32 gave some inconsistent results) to see how it
would do, a couple of days ago, and it apparently uninstalled the CPU
micocode patch that had come in the F4 BIOS version to fix the CPU
temperature monitor reading problem, and I say it this way, since the
original error was also reported in the BIOS temperature reading as well as
the Gigabyte utility (K8NS Pro mbd), and after the upgrade flash, the BIOS
report was correct as was the utility's. The BIOS has a selectable beep
warning which I keep enabled, and as soon as I used the PC Wizard function
to check on the identity and features of the CPU, it started beeping at
me--I immediately checked the utility, and it was reporting temps of 110 deg
C! The processor heat sink didn't feel hot, and rebooting the machine
returned it to normal when the BIOS reinstalled the patch. It was
repeatable, PC wizard working just fine until checking the CPU. So I can't
say that it didn't do something less obvious that might have led to this,
but it doesn't seem likely.
If I strip things off the computer, all I can strip is the modem and the
sound card. The sound card, Audigy 2ZS, makes some sense, as they can be
troublesome, but there hasn't been any sign of trouble on the installation
phase, as far as it was concerned. All the troubles I had were with the
on-board stuff--SATA, RAID, IEEE 1394, extra IDE ports, AC97 (disabled),
LAN, parallel, serial, USB, but I got around those by installing with
different combinations of disabling in the BIOS until I got one that worked,
then re-enabling them, and letting the drivers install then. That's part of
why I'm not keen on going back to square one. Apparently W XP considers
IEEE 1394 as NICs? And another curious thing: W XP thinks the machine has
WAN capabilities also? This one doesn't according to the mbd manual,
anyway, but I couldn't seem to make Windows give up the idea.
Having nearly shot my bolt on this, the only thing I can think of trying
is to replace the drivers in safe mode, and this is a little uncertain for
me, since DM has always insisted that the nVidia chipset driver is not
installed, even though I had installed it early on, so I'm not sure how I'm
going to achieve that short of an 'install over the top of' type of
approach.
Welcoming any and all suggestions or thoughts, thank you for your time.
