BSOD and various stop errors!

[sutrer]

Hey people, really hope someone can put me in the right direction??!!
Over the last couple of months I've been geeting alot of BSODs and various stop errors as follows:-
0x4E, 0x8E, 0x19, 0xD5 etc There are more, I could go on and on!
I've changed my graphics card, psu, new fan for cpu, reinstalled and up dated graphics, sound, bios, all usb drivers, basically all drivers I can think of!
Have ran memtest with no errors( although I know it's not 100% reliable).
I have even completely done a new install and reformatted hard drive but still these BSOD keep coming!
The most recent BSOD was as follows:-
Stop: 0x0000008E (0x00000005, 0x80574DBC, 0xEDD18478, 0x00000000)
I know that it maybe ram or motherboard but as am sure you can appreciate, but if possible I'd like to know which one before I spend my money!
I've attached the most recent memory dumps to have a look at as I'm not overly confident on reading and interpreting these! Any help anyone could giveme would be greatly appreciated?! Thanks in advance

Hi,

I believe that it is hardware problem. The stack trace of your first minidump is crashed at MmCheckCachedPageState. Probably the L2 cache memory of the CPU or the RAM is bad.

Hi there, thanks for the reply! Is there anyway of narrowing it down to either L2 or ram memory?
I've attached some newer memory dumps that occured yesterday evening. Hope they help!
Don't know if its just coincedence but all these bsods started back in the beginning of November within 2 days of installing new Xerox 19" widescreen monitor and downloading WMP 11 and IE7!
Am running XP pro with service pack 2
Thanks again for your help

The latest minidumps are also crashed without pattern and it is the symptom of hardware errror. Run memtest to stress test the ram.

Your windows also have faulty version of ZoneAlarm and ATI. You had better upgrade or de-install ZA. Upgrade ATI to latest version.

Hey there, thanks again for threply. I've noticed particularly in the last day or so, that it seems to be crashing when using anything intensive such as Nero vision express. Have de-installed Zone Alarm security suite and have now installed just basic zone alarm firewall.
The version of ATI I have installed are latest drivers bundled with Catalyst Control suite- Why would they be faulty? Any ideas?
I also made sure I completely deinstalled all previous ATI drivers prior to upgrade!
Have ran memtest a few times for a few hrs at a time and no errors. I know some faulty ram can pass memtest so what is my next step?
The ram I currently have is 2 x 512mb DDR Ram PC3200 branded as Matrix which I personally haven't heard of before. Should I replace with 1 stick of 1GB?
By the way here is a brief spec of my current system:-
Athlon XP 3200+
500w PSU
Asrock K7V88 motherboard
ATI Radeon 9250 AGP 8x
M Audio Delta Audiophile PCI
2 x 512mb DDR Ram PC3200

Here are the latest minidumps from yesterday

Hope this helps
Thanks again

Well, yesterday I went and took a leap and bought some new memory 1x 1gb ddr pc3200. Installed last night and stressed the ram to the full andtried using nero which was one of the things that would cause bsod and so far so good!! ) I will keep you posted with updates in next few days.
Thanks for all your help and fingers crossed!

Well what can I say-got bsod's again this morning. Everything had been fine and i decided to shut down pc. When i restarted I went into the bios as i wanted to make sure that my new ram was running at ddr400 speed-saved settings- and when pc tried to reboot came up with stop error 0x0A. tried to reboot again and another bsod with 0x7f and then another with 0x8E. lowered the speed on memory again and managed to get back into windows.
Now when I looked at dumps one said "probably caused by ntoskrnl.exe" and another said "probably caused by memory corruption".
Anybody any ideas what might be going on as this is brand new memory??!!

Anyway next step, I thought maybe some files were corrupted form previous problems over last few weeks so decided to do repair installation of xp.
All was going well and xp had got to the installation screen saying 35 mins til installation complete when it came up with message asking for VIAAGP1.sys filter driver. tried installing from via4 in 1 disk but no joy. If you click cancel on requested driver the repair installation just seems to hang!
I'm really stuck now on what to do
Any help anyone could give would be greatly appreciated.
Cheers

Maybe the contact between the ram and the ram slot has intermittent connection problem. Reseat the ram to another memory slot.
