driver_irql_not_less_or_equal error message Hi everyone, recently I have had alot of trouble with my laptop (Dell Inspirion 5100 p4 2.8 ghz). I kept getting the driver_irql_not_less_or_eqaul and the page_fault_nonpaged_area error messages. So I ran a diagnostic test and it said dst_short_test:failed. So I replaced the harddrive. It wouldn't let me get through the windows install because the blue screen would come up. So I replaced the memory. Same problem. Finally, I did more research and learned overheating maybe a problem. So I took apart the laptop and cleaned the fan and heatsink. Finally, I was able to install windows but when I try to download updates for SP2, the computer freezes. Basically whenever I try to run any diagnostic programs it freezes. Occasionally a blue screen will come up with the "irql" error message or it will be just a blue screen saying to restart the computer. I am attaching my minidumps and any help would be greatly appreciated.
