Hi,

When playing some multiplayer games my computer will suddenly reboot itself. I did a bugcheck analysis of the minidump and it came up with this. I can't make hide nor hair of it so would appreciate a look by an expert :).

The crash only occurs when I am running Battlefield 1942 but never occured on my previous machines. The crash has occured on 8 occasions, every time I was playing a game online. I can't remember if it reset itself during any other game. It always relates to ntoskrnl.exe

Abit AA8 Mobo

Just had a thought about this one. Windows doesn't think I am using two processors does it?

"Windows 2000 Kernel Version 2195 (Service Pack 4) MP (2 procs) Free x86 compatible"

There is an option in my BIOS which relates to multiple processors which I believe is enabled (it recommends that it is disabled for any XP based system, however I have Win 2K SP4 (With rollup update)). Could this be causing this error?
 
I have W2K/SP4 on my PC as well, but I've never seen that MP (multi-processor?) (2 procs) or anything like it on my (single CPU) PC.
Unless you have 2 physical CPUs, disable that option.

Give us your PC specs just in case.
 
It is actually installed as such. Under "Devices", "Computer" it has "ACPI Multiprocessor PC"...according to my IT guru, that is because the HT tech on the P4s pass off the one processor as two...hum.

Anyhoo...I loaded BIOS optimum defaults then the only thing I did was disable onboard sound and change my SATA drive from IDE to AHCI mode...(Windows was installed with relevant drivers for that). Not sure what the prob is, but hopefully setting the bios to the way it was before should help...if not I'll be back. Should anyone understand what an 8086 is, or can explain what is going on when the machine is "Waiting for multiple objects" then I would appreciate that!
 
Windows 2000 supports MultiProcessors, as well as Intel's HyperThreading, BUT W2K does not distinguish between physical and logical processors, it simply fills out the license limit using the first processors counted by the BIOS.
The 8086 was the first 16-bit CPU that Intel made, and the original base for newer CPUs such as 80186 (rare), 80286 (the famous AT), 80386 (first 32-bit and FPU), 80486 (Pentium) and currently 80586 (P4).

I don't understand the mumbojumbo about 'waiting for....'
A search on the web confuses even more.

Have you tried playing it with HT OFF?

I have two cases which simulate to your case and they are hardware problem. According to my experience, you cannot base on a minidump to conclude the problem. You need to process 5 to 6 minidumps and analyze the failing pattern in order to conclude the problem. Software error is usally consisent and it always fails at the same instruction address. Hardware error usually occurs randomly and your windows will crash with different bugcheck code at different instruction address.

Attach the output of your minidump so I can confirm which hardware component is faulty.
 
My error has been consistent. It is always 8086 with all 0 arguments, and it is always ntoskrnl.exe. It has occured 8 times and is the only error I have had.

I also remember a random error message I kept getting which was "Device=ffffffff", which has now ceased.

One time after reboot due to this error, my post screen and windows start up screens were different sizes and I had to manually adjust them to fit on my monitor, could it be my monitor drivers (which Win 2K SP4 rollup really didn't like)?
 
Attached. All instances of same error + DxDiag report. I'd be interested for any feedback.

I think this is memory corruption and stack trace is corrupt as well. The memory corruption may be caused by hardware or software problem. The stack trace has the footprint of iaStor.sys.

Suggestion
1. Upgrade SATA drive iaStor.sys
2. Upgrade or de-install Zone Alarm as your version has known bug

Played BF1942 last night...no crash and I was on for a long time...so maybe it is sorted. I'll report back with any problem!

Cheers
 
No, I don't know if there was a need to upgrade iastor, however I did install an Intel Utility for managing AHCI drives that wasn't present before. This seemed to do the trick. I'll do some proper tests on it tonight, but as far as I can see the problem has gone. Teething problems with my self built machine no less!

Thanks again for your help, I'll post any errors I get here should they reoccur.
 
Thanks for your reply. I get an similar problem at another forums and he does not install ZoneAlarm. BTW could you tell me which intel utility that you install?
 
Thanks a lot. There have several cases at other forum failed with bugcheck code 8086. Your solution may help them to resolve their problem.
