random blue screens, unsure of dump output

Thanks for the quick replies.

Digger - It's an old Cicero desktop. After cracking this thing open, it looks as though it has only been open once for the ram installation. It looks pristine. Cables are good. Nothing on the motherboard is damaged or leaking. I'm curious about the PSU. I wish I had a tester on hand. I'm still kicking myself for not picking one up on the weekend when I had a chance.

cpc - I think that was the first log I posted. I haven't seen that error since. They seem to change every time. Here is the most recent log I received earlier tonight. It looks as though this problem is a memory write error:

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffc6bb2, memory referenced.
Arg2: 00000001, value 0 = read operation, 1 = write operation.
Arg3: bf873c8a, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 00000000, (reserved)

All of the crashes are with different symptom. As hardware error occurs randomly and software error usaully has the same error pattern. This problem is related to hardware.

 

This has been my feeling the whole time as well. But I wanted to be completely sure beyond a shadow of a doubt before proceeding. I prefer software errors, as they're very specific and consistent. It's a real pain in the arse trying to narrow down a hardware error when everything appears to check out on the surface. Ram scans come out fine(although I know memtest is not infallible). The hard disk is fine as well. I'm not 100% sure about the PSU, but I've swapped it with another with no luck. If there's a short on the mainboard, I doubt there's anything I'll be able to do for the owner. I simply don't have the diagnostic tools on hand to check anything beyond the hard disk or the ram.

Thank you folks for all of your help. You've all been a great melting pot of ideas. It's good to hear things from a different perspective.

 

You are right memtest is not 100% accurate. If RAM problem occurs at kernel mode, windows crashes with blue screen. If RAM problem occurs at user mode, the application program crashes and generates DrWatson log (by default DrWatson is enabled). Refer C:\Documents and Settings\All Users\Documents\DrWatson\drwtsn32.log (XP). If you have a huge DrWatson log and they are crashes with access violation, it is another symptom of RAM problem.

 

Unfortunately, I don't have a Dr. Watson log containing any errors. I've formatted since the regular user errors were popping up. Other than that, I've posted the majority of the blue screen memory dump errors into this thread. But yes, for a time, I was receiving a mixture of both error types you describe.

First thing in the morning, I'll grab a PSU tester. I need to get one for my kit anyway. I guess now is as good a time as any.

 

Update and final note: Turns out it was the 1 gig stick that was faulty. I finally got my hands on some spare ram and let it run. No problems whatsoever now.

Thanks to all of you who chimed in. You've been a big help.

 

Ditto. Very pleased to learn you figured it out. Nice job.



edit: I guess I had you "losing" the wrong piece of memory.

 

Ditto here too.

You even prompted me to buy a digital display PSU tester from Newegg today for my own toolkit. Up till now I've just been keeping a spare PSU on-hand for the next time my computer starts flaking out on me. I've had to replace my PSU on more than one occasion and a friend also had a PSU go bad once so I figure a PSU tester will be handy whenever I'm called upon to troubleshoot a computer.

Thanks for the idea!
