Windows crashes randomly, and reports system error 102, category 1003 when restarts. I have collected these 5 minidump files from crashes. I don't know if they are caused by damaged ram stick or some faulty driver. System specs are the following: Intel Pentium 4 520, 2800 MHz (14 x 200) Hewlett-Packard HP Compaq dc7100 CMT(DX438AV) Intel Grantsdale-G i915G Intel(R) 82915G/GV/910GL Express Chipset Family (128 MB) DIMM1: Nanya (256 MB PC3200 DDR SDRAM) DIMM2: Transcend (512 MB PC3200 DDR SDRAM) DIMM3: Transcend (512 MB PC3200 DDR SDRAM) PSU: 400W OS: Windows XP Professional SP2 up to date of Windows Updates. No recent changes in hardware/software, except latest windows updates after first crashes trying to fix the problem. I have also tryed to delete memory pagination file, without success. I hope you can help me. Thank you for everything.
