about 3 weeks ago i installed 2 new hard drives and 1 gb (2 x 512mb) of memory (so now theres a total of 2 gb of memory 4 x 512mb), and we installed norton internet security 2007 to replace her norton antivirus 2005. i did use the norton complete removal tool as per nortons instructions before installing internet security 2007. we have 2 hard drives (c and f, with c being the main drive and f being the backp). we use casper xp to clone the main drive once a week on the backup, so in case of any hard drive failure, the most work we can lose is one weeks worth. my sister noticed that since we upgraded the hard drives and memory, her system appears to be slower and there have been random crashes and blue screens of death (bsod). we had a vundo virus infection and now it has been cleaned. the c drive failed and i had to send it back to seagate for a replacement. so i took the now clean f drive, which was the backup and installed it as my c main drive. it boots up with no problem. but we have been getting many bsod. one of them said something about _pool_caller. another said fault in non paged area. and today one bsod said we should disable all antivirus, 3rd party disk defrag and any 3rd party backup utilities and check the hard drive configuration. it also said on this bsod to check updating the drivers and then it said i should run ckdsk/f. the weird thing is this drive is no longer the f drive, and it should be saying ckdsk/c. i only have one drive in my computer and its the c drive, which is the main drive now.
we have also been getting alot of iexplore nees to close errors which kicks us off repeatedly. my sisters machine is about 3 years old. its a dell 8400 running windows xp sp2. she has norton internet security 2007 and doesnt use system restore as she uses norton goback. goback has been on her system for years, so i know thats not the problem.
i would appreciate any help in trying to get this problem resolved. as i said, its only been happening for 3 weeks since we installed the new hard drives, 1gb more of memory and nortong internet security 2007. thank you in advance for any help you can give me. take care.
