I have a Dell Studio 1555; Intel 2 Duo CPU, T6600 @2.20GHz, 4 GB RAM and it has worked great up until 3 days ago. There was an issue with our ISP being down this past Saturday. Once they got it back up and running, I used the internet for maybe 20 minutes and then got the first of many BSODs. This first one stated irq_not_less_or_equal. I could only boot in Safe mode (would not let me in normal or safe with networking). This happened multiple times, I did a system restore which worked for 5 minutes then another BSOD. Ran my virus removal tools (SuperAntiSpyware and Spybot S&D) to no avail. Today I turned the computer on and this BSOD message stated Service_System_Exception. I've run memory test on it which found no errors. One of the .dmp files stated that the ntoskrnl.exe driver was bad? I have attached the zip file with the .dmp files. Can someone please offer some guidance on this. I feel as my last step is to reinstall the entire operating system. Thank you for any guidance.
