my business has tanked with the economic crisis, and it looks like all

How to cut expenses? That's easy: don't build that new system.
So I have this older but reasonably powerful system that has two
nagging problems, and I want to finally fix them, because it looks
like I'll need to keep this system in service for at least six months,
probably longer.
1. When I am doing intensive disk operations, the system keyboard and
mouse pretty much seize up. That includes a copy/move operation to
another system over my home LAN. Also a chkdsk operation, which I
have to do frequently because of all the crashes.
2. My system crashes way to often. It happens only in these
situations:
1. I have just opened up Outlook 2003 (no comments, please!) and
Outlook is listing all the "reminders." I know I'm "safe" if Outlook
starts up and all the Reminders have been listed.
2. I click on a file in a window, so I can copy/move/unzip it. That
is, the crash never occurs during one of these operations.
What is weird is that my wife has almost the identical system, but
hers is rock-solid. I'd appreciate any suggestions to improve the
disk performance and track down these very annoying crashes. If I
could fix only one of these problems, I would focus on the crashes,
because they waste so much of my time.
Here is the system, which is not overclocked:
Asus A7M-266D motherboard.
Twin Athlon XP 2000, unlocked to MP. (Device Manager sees 2 MP
2000+.)
2 x 1 GB of Micron memory
Matrox Parhelia 128 video card. (My wife' system has an old Matrox
card.)
Adaptec SA-2100 SATA controller with 4 x 320 GB Seagate 7200.10
drives. (My wife's system has a vanilla PATA drive.)
Logitech MX 3200 wireless keyboard and wireless LASER mouse. PC Power and Cooling Power Supply. I forget the exact rating, but it
is at least 500 W.
Pioneer DVR-111D DVD-RW drive. (My wife's system has a Lite-On CD-RW
drive.)
LSI Logic SCSI adapter, with Exabyte 8 mm tape drive attached. (My
system only.)
Win XP SP 2 with Microsoft auto-update.
Thanks

(other I/O)
One of the problems with the chipset, is the performance
of the PCI busses. Something like a 25MB/sec transfer
rate limit may be observed, on the three lower
slots.
Test with HDTach or HDTune.
HDTune 2.55 is free, and does a read-only benchmark. With properly
functioning busses, and normal I/O interfaces, you should be able
to see the gently curved characteristic, of disk I/O performance.
For example, my disk might offer 60MB/sec transfer speeds near sector0
and 40MB/sec near the end of the disk. That would be while connected
to an ATA100 capable Southbridge port. Or, I'd see similar if
I used my Promise Ultra133 IDE card, plugged into a PCI slot.
As far as I know, the PCI bus on my current motherboard,
delivers 110-120MB/sec on the 32 bit/33MHz bus.
http://www.hdtune.com/download.html (also has an Info tab, good for IDE disks)
http://www.simplisoftware.com/Public/index.php?request=HdTach
If you run the benchmark and get a flat line, limited to some particular
speed, then you look to cabling or bus issues. So you might even see
a straight line clipped at 25MB/sec.
I think there are other benchmarks around, like one by Atto. i don't know
if HDTach or HDTune are limited as to the disk interface or not.
For your crashing problem, I don't have anything to offer there. In
Linux, apparently you have to switch to MPS 1.1, and use NOAPIC
to get booted, but after that it works. I don't know if any of that
has implications for Windows or not (like whether Windows would be
upset by some aspect of that motherboard + BIOS or not).
******
Based on the above -
1) Try slot juggling, remembering that putting a lower speed
card in the 64 bit bus, will slow everything down. Try to
host the disks you use off a controller located in a 64 bit
slot. Put all the "loser" cards, in the lower slots.
If you need to free up a slot, host the backups on your
wife's machine :-)
2) For crash debugging, simplify the setup (disconnect stuff)
and try whatever test case is easiest to create a crash.
As an alternative, you could do more testing in Linux,
after getting the appropriate info as to what command line
switches would work best to allow booting the system. If Linux
refuses to crash, but Windows does, it may imply that Windows
isn't crazy about that dual processor setup.
Perhaps the 2cpu.com forums have more comments about these
762/768 dual socket motherboards. Several manufacturers made
them. You can search the 2cpu.com domain, using this search
engine, and entering 2cpu.com for the site to be searched.
There are some people who are stable, and other people who
have tried everything, and still crash.

As for upgrading, you could go for a low end AMD system,
and at least get a system that doesn't crash. Of course,
finding a motherboard with the slots you need, is going
to be a problem. Even a low end dual core should be
comparable to the crash-box you've got now.
HTH,
Paul
