I have a gigabyte motherboard MA709XTUD4P. I have a problem which arose after I plugged in the connection for a set of wireless headphones. The system crashed after a min or two. I saw that several audio drivers were no longer detected under device manager and reinstalled them under safe mode in windows XP home as windows would not load. Now I can not open windows even in safe mode. I tried a "repair" under the recovery console. No help. Any suggestions? I'm thinking I may have to reinstall windows, does this mean I have to reformat the disk? Any ideas would be greatly appreciated.
