Please some kind hearted, help me found problem using the atatched 10 debuglogs thus generated during past few days., (i also have many more minidumps, if required.)

debuglogs.zip

From the few ones I looked at, the crashing app varies.

Write a memtest86 boot CD to test your memory: http://www.memtest86.com/download.html

Test your hard drive for errors with the diagnostics utility provided by your hard drive manufacturer.

Test hard drive SMART status and system temperatures with SpeedFan: http://www.almico.com/speedfan.php

If the memory tests OK, then this will be a kernel mode driver misbehaving. Can you enable your machine to do a complete memory dump, and provide the zipped .dmp file somewhere for us to look at the next time it crashes?

Will definitely run the memory test tonight and tell you about the results, I had ru the test for around 10 minutes but found no error.

Complete memory dump will be of around 1GB and zipped i dont kow how much, that will be huge to upload on the forum or elsewhere? Is there anyother procedure to find the culprit?

Note: Also, one thing i noticed today, when i replaced my new SDRAM (133 2*512GB) to Old ones' (2*128MB), thus having 256MBSDRAM, my windows XP on starting says,

"system32/drivers/pci.sys file not found...press 'r' to repair..."

When i replaced back the RAMs to 1GB, it didnt said so, in a way it found that file! isn't funny?

OR, some cable got loosed while replacing RAM?

Will tell u about the SDRAM Tests.

Thanks.
