AMD Ahtlon XP processors combined with AGP display adapters can cause blue screen of death (BSOD) along with Windows locking up or freezes.

By disabling Windows from using the Page Size Extension (PSE) feature of the CPU (Central Processor Unit), then these problems should disappear:

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Session Manager \Memory Management]
LargePageMinimum = 0xffffffff

More Info MS Q270715

Note disabling PSE will disable large pages (4 MB instead of 4K) but will enable write protection of the memory area for the kernel. Large pages increases address translation performance and makes it possible to use a single TLB (Translation Lookaside Buffer) to map 4 MByte of RAM and increases the non-paged pool limit to 256 MB (Instead of 128 MByte). The large pages are used to map the Windows core into memory like: NTOSKRNL, HAL, nonpaged pool, and the PFN database.
