I am working on an Inspiron 1525 running Vista Home Premium with 3 GB ram. I can boot and run in safe for a while before it locks up. All my security software is up to date and I have run several good scanners. The system is clean. I ran a system diagnosis and it show the ram memory is running fine. When I do a normal boot, I get the BSOD fairly quickly. Several different error messages appear one of which is the suggesting to reseat the memory, which I have done 3 times with a grounding strap. Here are some more: "A driver corrupted pool memory used for holding pages destined for disk" "Memory test fail Dimm B" (which I think would mean Dimm 2 which it is marked. "error code 123' ( I also have a long stop code) If all of this shows a bad memory stick, why does the system still recognize the 3 GB? My guess is that maybe a page file is corrupt or even the OS. Should I just do a system recovery?
