BSOD - irql_not_less_or_equal (usually)
Good Afternoon,
I am having some issues with a customers computer. They initially told me that they had a virus infection, and that the internet would "stop working" after being on the net for about 2 min. Once I started my troubleshooting i noticed that the computer would BSOD (irql_not_less_or_equal) after about 10 min of any activity, network or otherwise. I called the customer back and informed them of what i was experiencing. The customer informed me that this is normal. Final report/analysis from customer: "After about 2 min after I'm on the internet, the computer would either freeze up or BSOD."
Restarted into safe mode and got better results I was able to run MBAM and remove about 820 infected items. Once this was complete (still in safe mode) I was able to browse the web and shutdown properly.
Upon restarting windows normally, I was able to log onto the web and surf around for about 10 min or so and then it BSOD again this time SYSTEM_SERVICE_EXCEPTION.
I shut it down, and proceeded to open the unit (alot easier than i thought) to troubleshoot RAM (swapping out with known good), apply "Artic Silver" to heatsink and CPU, and Clean dust and debris form fans and heat sink fins.
Restarted and after about 4 min got BSOD (irql_not_less_or_equal) but this time it had ataport.sys underneath (i failed to copy down the Hex).
This is when I decided to join this forum and see if I can get any help with this issue because It has me completely baffled. I followed the instructions posted by jcgriff2 on t he sticky. I was able to do all steps except for PERFMON /REPORT. When i tried to run the app it stated "Error: An error occurred while attempting to generate report"Information:Steps I've taken:
