what happens if you chose boot to "Last known Good Configuration" instead ?
SFC should not have caused this as it simply repairs any corrupted system files by comparing them w/ a original copy created during original install of the OS. Where there's deviation, it replaces the current corrupted file with a clean, original copy.
If the original copy is corrupted, it would ask for your OS CD or SP CD or install file location & get from there.
There was a known conflict between AVG AV 7.5 & Roxio Drivers for versions 4.0 thru 7 CDRAL. There was a correction tool. I'm not sure IF such a conflict exists w/ AVG 8. Possible I suspect. Recall seeing a post saying AVG * wanted poster to update to a NEWER Roxio/Sonic version.
I am unable to boot pass windows scroll bars at boot up stage. Yet i boot up with no problem in safe mode. This all began after i ran "sfc /scannow". I ran this program because my system OF late takes forever to open a program on first attempt and Roxio begin to refuse/freeze to create DVD. system is virus free and malware free as AVG 8.0, A Square and Ad-aware keep me running real clean.I have research your archive on this issue but none quite help.
System info is: AMD Athlon, 800mhz, 1024mb, XP-PRO & 40ghd . HDDrive was defrag yesterday, and i also rolled back my NVIDIA driver but to no avail. Your expert help would help. I am reaching you via my sons computer.
