I am having trouble with the autocheck after a reboot. it says I have an unspecified error due to some unspecified software. it tells me to use system restore to fix this. system restore cannot go back far enough to correct the problem. so now system restore won't run because I have errors and autocheck won't run to fix these errors. I uninstalled Norton 360 back in December and read somewhere that may be the culprit for the autocheck error. I have tried everything from checking the boot execute value to chkdsk /f /r to no avail. everything seems fine but I still can't fix any errors on restart.
