memtest is not a Windows executable program (it's acutally Linux-based), so you need to make the boot floppy (or CD). The process is really pretty easy.

I suggested that you check the RAM and other components first not only because the errors often point to a hardware (or driver) problem, but also because you said that you just built the machine and have been getting the errors since then. In other words, you could waste time looking for a software/program fault when in fact, you may have a faulty/mismatched/mis-installed piece of hardware.

ran the memtest for over 2 hours, no errors


ok ok update


i just got another error, this time it said the IRQL error, but it said the driver was HIDCLASS.SYS

USB related?


thanks in advance

to add onto the IRQL BSOD's, i get one with ha20x2k.sys also, which is a Creative Labs X-Fi Sound card driver. And yes, i have installed the newest drivers and it was doing this before i installed the new drivers. GOD HELP ME haha. . . . i really appreciate you bearing with me.

This thread pretty much covers all of the suggestions that I was going to post here. The three main areas covered in thread above are:

* Further steps to qualify/disqualify faulty RAM as a possibility.
* Verification of your hardware and driver compatibility.
* In-depth analysis of the "dump" files created by the BSODs.

The troubleshooting steps in the thread are very well detailed, so it shouldn't be too daunting to try the suggestions. Post your results, and/or any questions, here.

As this is one of the first posts that comes up on Google when searching for "Error code 0000001a", I figured I'd post my fix here...

Despite all the suggestions around checking for bad memory, the culprit in my case was that my Server 2003 virtual hard disk was running low on disk space. This was likely causing issues with the pagefile - hence, the potential "memory" issues. As soon as I freed up disk space, the 0000001a errors went away.
