Did some reading on BSOD fatal exc. errors 0028:00000013 and have a couple tips.
I read in several place that it could be bad ram. So it wouldn't hurt to check that, and possible take our your ram, and swap slots.
MOSTLY I saw the error in reg. to Mcafee anti virus, and EZ CD creator. Not really a good reason why. Do you use either of these products? Consider removing the cd creator if you have it, and disabling mcafee on boot up and trying that also.
I would do the usual spyware scans (AD-Aware, Spybot, SpyKiller) and see if they pick up anything.
