Not every utility is something that works. Toss it and go back to what worked.
Since you can't boot SAFE MODE (either key fails), then you need to boot the SAFE MODE command line mode (I forget the exact words it uses) and then run RSTRUI to get to System Restore.
I had problems with a gigabyte utility program for my AMD 1800 so having the day off decided to re-install the utility ( I think it regulates cpu ). Well, after that the machine re-starts loads Windows XP and goes to the log in screen like normal. I log in and start-up begins loading the programs. Then at some point before completing the start-up tasks it reboots. It keeps doing this. I have tried to start in safe mode f5? and same thing... I tried restarting hitting f8 same thing ?? Thanks for your help you guys arefantasticwith this stuff!!!
