Hello, I currently have an issue with my PC, a Dell Dimension 4600. I am unable to load up WinXP. I have been putting in countless hours of research and inquiries into this problem. I have found others who have written about similar situations on various forums, but have yet to come across a solution. So, here it goes: As previously mentioned I own a Dell Dimension 4600 (I know, get a new computer right?). Windows XP Home Edition. Intel Pentium 4 Processor: 2.8 Level 2 cache: 1 MB Integrated BIOS version: A09 Problem: Power on the computer and it briefly loads before showing me a black screen with white lettering that states: Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM Try to load from every option from the "Windows Advanced Options Menu" (ie. Safe Mode, etc.) and none of the options changes the outcome. Ok. So, I go into setup and change the boot sequence to load the WinXP Reinstallation CD. It does it's thing, loads up and brings me to the "Windows XP Home Edition Setup" screen. I have 3 options (as I'm sure whoever is reading this already knows); (1) set up WinXP now, press ENTER; (2) repair using Recover Console, press R, (3) quit setup. Now, going through the process of either option 1 or 2 results in the same error message screen or BSOD. Option 1, I get the BSOD after pressing F8 for the licensing agreement and option 2 I get the BSOD after selecting "1: C:\WINDOWS." The specific BSOD is: BAD_POOL_CALLER 0x000000c2 (0x00000043, 0xc217c00, 0x00000000, 0x0000000) There hasn't been anything installed on the computer for awhile. I'm not too concerned with what caused the problem as I am how to fix it. At this point I can't even use the disc to reinstall windows. I can't do anything. I've ran all the tests provided from the "IDE Drive Diagnostics" option, all have tested good. Any and all help would greatly be appreciated, I am at a loss for what my next step should be in fixing this problem. My apologies for the book that I've written, I just seen way too many posts on various forums with incomplete/useless information. Thank you.
