System Instability Issues - Help!

B

Brad Wenner

Hi,

Through a program at my school I got parts to build a computer for
little cost to me. I've got it up and running, but I am having major
problems with stability. It was randomly rebooting itself (one time
while opening Outlook, another when opening Photoshop, another while
doing nothing, another while playing a game - it happens every few
hours no matter what I'm doing). I turned off the auto-restart option
in XP to see what it was and I'm getting mostly STOP code 0x0000008E,
and occasionally 0x000000C5. Neither point to a specific driver or
hardware device. Occasionally I also get "Generic Host Control
Processor has been terminated, system will reboot" error and a
countdown before it reboots.

It's not the RAM, I let memtest86 run a few times and it came out
fine, and I don't think it's because of an underpowered system (my
power supply is 400w). Heat shouldn't be an issue either, the case
temp is around 32C and the CPU 42C. I have the CPU heatsink plus 2
case fans in it, airflow is good.

My hardware is:
-Syntax SV266A Mobo (VIA KT266A chipset, w/ onboard sound and
ethernet)
-AMD Athlon XP 2400+
-256MB DDR PC2100 Kingston RAM
-Geforce 4 64MB 440 MX
-Western Digital 100GB HD
-Optorite 52x CDRW
-16X DVD

I'm running Windows XP. According to Device Manager, I don't have any
IRQ conflicts, but looking in the System Information utility I'm
seeing that my USB Host Controller and onboard audio (VIA AC'97) are
sharing IRQ 10, and my Geforce is sharing IRQ 11 with another USB Host
Controller (two of them are on IRQ 11 actually) and my onboard
Ethernet (VIA Rhine II). Even though WIndows says there's no conflict,
could that be the problem? How can I make them not share to make sure?
I know how picky some of these graphics cards are.

Anyone have any ideas of what could be causing random STOP errors like
I'm getting? I have a feeling this has to do with incompatible
drivers/hardware, but I've tried various things and can't seem to
figure out what it is.

My guess is still RAM. Slow down the FSB setting in CMOS and see if
you gain stability. Since you are using PC2100 RAM I would assume you
are at 133. Try 100.

If it is stable, either get better RAM or buy some PC2700, as it will
provide a cushion when used at 133.

Not sure why this fixed it, but I got a 512MB stick of RAM (still
pc2100) for Christmas and plugged it in and my box has been rock solid
all day. Strange.
