I had posted earlier in the AMD CPU section about my overclock, and decided to try tweaking things some tonight. Well things went bad. On the Abit Guru overclocking program that I used, I tried a bit higher overclock and as soon as I did that, the program occured an error and had to close, then Windows shut down explorer etc, my desktop went blank and so I hit restart. The program had never done that before and had always worked well for me. When it tried loading Windows back up, before the XP screen, it comes up with an error that the file: C:\\windows\\system32\\config\\system is missing or corrupt!!!! Is there any way to get my system back without formatting and installing windows again!! Any help is very very much appreciated.
