Hey! I decided to come to TechSpot for help because people actually seem willing to help. I have a year-old HP Pavilion dv4000 laptop. It has an Intel Pentium M processor and 1.60 GHz with 504 MB RAM, that runs Windows Microsoft XP Professional Version 2002 with Service Pack 2 also installed. I seem to have the same problem as the original poster. My computer used to run amazingly. I have Norton Internet Security/Anti-Virus 2006. I installed Kensington Bluetooth recently and ever since then my computer has been crashing. I've never seen the screen that comes up though. However, I do receive the following messages - C:\DOCUME~\OWNER\LOCALS~1\Temp\WERa2d6.dir00\Mini062306-01.dmp and C:\DOCUME~\OWNER\LOCALS~1\Temp\WERa2d6.dir00\sysdata.xml. I believe these are STOP errors, but I am not for sure. I've repeatedly run my Norton scans, along with Ad-Aware and Windows Defender (which runs scans daily as does Norton) to no avail. I do not believe that my OS is running faulty. I had to reinstall it in February due to a virus. Again, the crashes only started after I installed the Bluetooth hardware. Any help would be great, thank you!
