Problem just started this past week, when trying to read any of my CD drives, and when trying to connect a WD My Book Elite backup drive I receive a Bad_Pool_Header message just after system crashes. Also in text of error 0x00000019 (0x00000020, 0x848A0760, 0x848A0778, 0x1A030001) I am behind the times, using Windows XP Home, Svc Pack 3. Would appreciate guidance, MS knowledge base had several of the Bad_Pool_Header errors, but no articles seemed to specifically show the error codes I am receiving. Thanks1 person needs an answerI do too

The referenced bugcheck indicates memory corruption. This could mean faulty hardware such as memory, or a bad driver. There are a variety of things you can try to do to determine what is going on. Consider running chkdsk on all partitions. Let chkdsk complete on each partition and see if that helps. It can be helpful to use Driver Verifier. To enable Driver Verifier... start->verifier.exe->OK->Create standard settings->Next->select driver names from a list->Next->sort by Provider->select all non-Microsoft drivers->Finish, and OK your way out of the dialog. Then, reboot and use the system as you normally would, and wait for a problem. In the event that the system does not boot completely after enabling driver verifier, boot into Safe Mode and run driver verifier, and tell it to delete the changes. Wait for a bugcheck to occur after enabling verifier as described, and then upload the dump to your SkyDrive, and provide a link. Also consider running SFC /SCANNOW. If you boot into safe mode, do you still experience bugchecks? What about if you do a clean boot? Consider testing memory with Windows Memory Diagnostic or memtest86. Note that memory that passes tests is not necessarily good memory - it just hasn't failed a test. Consider systematically eliminating RAM from the system - run with a couple of modules for a while, and see how things go. Then try the other modules. Other common suggestions include ensuring drivers are up to date (including video drivers), as well as ensuring that you're using the latest BIOS.
