Strange blue screen errors

Do I have a virus or is it Norton fault again? I haven't used this computer for some time. Usually I get the Memory dump/ Video card errors if I get any. Rare cases I get the Modem. I got some other error but didn't write it down.

The first error was a sysevent.sys type error (didn't write down the code) and happen after I logged on. The second one happen when windows started right before my system check for dual bios and the file again was a strange one, STPSC.sys or something like that. I google the first one and it says its norton but I wanna make sure.

sysevent.sys
The next time it happens write down the whole message. Then go to Norton's support site and do a search there
They used to have a patch

STPSC.sys
Do you have Daemon Tools?

Yea, but I think I uninstalled that program a long while ago. Do you think its time for a reformat?

I would download Autoruns and use it to disable STPSC.sys



To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.
