No More System PTEs (stop code 0X0000003F)
Page Table Entries (PTEs) are used to map RAM as it is divided into
page frames by the Virtual Memory Manager (VMM). This error usually
means that Windows has run out of PTEs.
Aside from the usual assortment of faulty drivers and services that can
cause all sorts of problems, this error can also occur if you??™re using multiple
monitors.
If you find that you??™re experiencing this error often, you can increase
Windows??™ allocation of PTEs with this procedure:
1. Open the Registry Editor (discussed in Chapter 3).
2. Then expand the branches to HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\Session Manager\Memory Management.
3. Double-click the PagedPoolSize value, enter 0 for its value data, and
click OK.
4. Next, double-click the SystemPages value. If you??™re using multiple
monitors, enter a value of 36000 here. Otherwise, enter 40000 if you
have 128 MB of system RAM or less, or 110000 if you have more
than 128 MB of RAM.
5. Click OK and then close the Registry Editor when you??™re done. The
change will take effect when you restart Windows.

Troubleshooting
NTFS File System (stop code 0X00000024)
This is caused by an problem reported by Ntfs.sys, the driver responsible
for reading and writing NTFS volumes (see Chapter 5). If you??™re
using the FAT32 filesystem, you may see a similar message (with stop
code 0X00000023).
Causes include a faulty IDE or SCSI controller, improper SCSI termination,
an overly aggressive virus scanner, or errors on the disk (try testing
it with Chkdsk).
