Hi, I've encountered the extremely annoying \WINDOWS\SYSTEM32\CONFIG\SYSTEM problem. I've followed the instructions on Microsoft support Article Q307545 (can't post the link as I'm a newbie here), but I couldn't proceed to step four (opening System Restore). If I try to boot normally, chkdsk opens to scan one of my partitions, the scan is completed and no errors are found, and then suddenly the computer restarts. If I try to boot safe mode (including with command prompt), the computer too eventually restarts. I've tried using UBCD4Win to move/replace the registry files like the Microsoft support site states, I've ran a full virus/malware scan, and I've tried using the RegResWiz tool to restore my old registry, but I've still encountered the restarting problem. I also tried opening System Restore by command prompt through UBCD4Win but there was no response.
