Hi! I had this blue screen error on my dell inspiron laptop. I tried the debugging tool on the minidump and here's the result;

IRQL_NOT_LESS_OR_EQUAL (a)
CUSTOMER_CRASH_COUNT: 1
DEFAULT_BUCKET_ID: VISTA_DRIVER_FAULT
BUGCHECK_STR: 0xA
PROCESS_NAME: System
MODULE_NAME: SRTSPL
IMAGE_NAME: SRTSPL.SYS

What will I do next? I kinda lost from where I am now. I tried the System Restore so that I can repair my Symantec Antivirus but System Restore is not working. I just keep having this blue screen error whenever I finished logging in then it will just restart again.

I note the last post in that Symantec thread says to uninstall Norton, probably not a bad idea
If you do uninstall Norton, make sure you run the Norton Removal Tool as well: http://service1.symantec.com/Support/tsgeninfo.nsf/docid/2005033108162039

I prefer Free Avira Antivirus (which is always above Norton in Virus detections, not bad for a free product)

How can I uninstall Norton? I can only open windows on safe mode. I actually tried it and it says you can't uninstall/repair when you're in safe mode.

I'd go to Safe Mode
Then locate: SRTSPL.SYS (through search)
Then rename it to SRTSPL.OLD

Try that

Hmmm... I just tried that and it's still the same. Do you think I need to re install my OS?

That's not possible
