Okay we can put this in the "don't try something new at 2 AM when you are tired and bored.
I have a Gigabyte Board with EASY TUNE 5 installed. I was just piddiling around with the Basic Settings and ran the overclock up and down just to see how high the numbers went, unfortuneatly I hit something that applied it. I know I was at 10, I am hoping that meant 10%. Anyway, the video went to diagnal lines, and that was the end of it.
Now I can log into another account on the same pc with only limited access. The EasyTune5 fails to load so it works fine. However, since I don't have ADMIN rights with this account I have no idea how to undo the settings on the EasyTune5 to stop it from trying to overclock each time the ADMIN account is loaded.
PC Specs:
MB: GA-M51GM-S2G BIOS F11 3-20-07
OS: MS Win XP PRO SP3
Options already tried;
1) System Restore through Start>Accessories>System Tools>System Restore
Insufficient Admin Priviledges.
2) Load Admin Account (ctrl-alt-delete) and stop the EasyTune5. (I don't know the service to stop)
I am drawing a blank on the work around I am used to. I know you can change the limited account to an admin, but not remembering how. I do have Win Ultimate Boot CD, as well as, Knoppix, so I can boot up without Windows loading. Any ideas would be appreciated, thanks,
