I read your first 6 minidumps and all are 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA and is defined as the following:
Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).
Unfortunantly there is something wrong with your minidumps because it said I didn't have the correct symbol package to debug your minidumps. However, I have read thousands of minidumps from systems running XP w/SP 3. So something else is going on.
Your dumps are also saying that timestamp for the core Windows OS driver ntoskrnl.exe could not be found. Generally OS drivers are too critical to be of much help. So, let's tackle this from another angle.
First, give us your system specs including your security software.
Second, Start > Run> type ChkDsk> click Okay. This has three stages. Tell us if after the second stage is done if it tells you it is Recovering Lost Files.
Third, how often do these BSODs occur? What are you doing? Are they random?
Fourth, run Memtest on your RAM. This test kicks in almost immediately at boot-up. See this link and follow the instructions:
https://www.techspot.com/vb/topic62524.html
Let it run for a
LONG time. The rule is a
minimum of 7 Passes; the more Passes after 7 so much the better.. There are 8 individual tests
per Pass. Many people will start this test before going to bed and check it the next day.
If you have errors you have corrupted memory and it needs to be replaced.
Also, with errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
* Get back to us with the results.
