Sporadic BSOD due to "halmacpi.dll" driver

I've been getting a sporadic BSOD which I think is due to my labview VI. The dump file claims that it's the "halmacpi.dll" driver that is to blame. Any idea where this driver comes from and how I can fix this problem? Thanks

So i've searched a good while and tried a few things (including rewriting my VI) and I just got the BSOD again. I know it deals with Labview since it only occurs while running my program. I'll attach my dump file if anyone can please help. Thanks

Sorry, had to do it again......^^^^


Go to the first link at geeks to go and read the post.  Someone got help around post #4 that seemed to work, it was some strange old driver causing the problem and had nothing to do with the program when the BSOD happened.

Hi Ian,


According to Google, ser2pl.sys is the driver for a USB-to-serial adapter. Do you have one of those? If so, you should contact the manufacturer.
