This error sure has been coming up a lot lately.

BCCode: 1a   0x0000001a 

The MEMORY_MANAGEMENT bug check has a value of 0x0000001A. This indicates
that a severe memory management error occurred.

BCCode: 1a   0x0000001a <- read this*1041.html?order=date

Unfortunately memory tests do not catch everything such as mismatched memory, when
slower memory is placed in front of faster memory, and other issues.

You can try Powering Off all power and removing and reseating the memory. One or two
stick(s) at a time if possible to see if the system bluescreens and if so on which sticks.

Other possibilities are BIOS and antivirus/antispyware/security programs and even
motherboard problems.

Drivers are possible however that would be unusual - maybe chipset drivers.

Look in the Event Viewer to see if anything is reported about those.

MyEventViewer - Free - a simple alternative to the standard event viewer of
Windows. TIP - Options - Advanced Filter allows you to see a time frame instead
of the whole file.

Could be a driver related issue though less likely than memory. Update your drivers
manually by looking at System maker and Device maker's sites.

This is my generic how to for proper driver updates :

This utility makes it easy to see which versions are loaded :

DriverView - Free - utility displays the list of all device drivers currently loaded on your
system. For each driver in the list, additional useful information is displayed: load address
of the driver, description, version, product name, company that created the driver, and

For Drivers check System Maker as fallbacks and Device Maker's which are the most
current. Control Panel - Device Manager - Display Adapter - write down the make and
complete model of your video adapter - double click - Driver's tab - write down the
version info. Now click UPdate Driver (this may not do anything as MS is far behind
certifying drivers) - then Right Click - Uninstall - REBOOT this will refresh the driver

Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd
party with their own software and drivers and any other major device drivers you have.

Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then
Device Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions.
(Look for BIOS, Chipset and software updates at System Maker's site while there.)

Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT
after each installation.

Always check in Device Manager - Drivers tab to be sure the version you are installing
actually shows up. This is because some drivers rollback before the latest is installed
(sound drivers particularly do this) so install a driver - reboot - check to be sure it is
installed and repeat as needed.

Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check
manually by model.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

How to Install a Device Driver in Vista Device Manager

If you update drivers manually then it is a good idea to disable Driver Installations in
Windows Updates, this leaves Widows Updates ON however it will not install drivers which
will usually be older and cause issues. If Updates suggests a new driver then HIDE it
(Right Click on it) and then go look for new ones manually if you wish.
