So I replaced the battery about a week ago on my mobo because it was losing the settings I have when it would start up. Normally runs at 2.66ghz but starts up on 4.0ghz. Never overclocked, so I dont know why it started doing this. I took out the battery for more than 30 mins and put it back in and it still doesnt go back to default settings. I also cleared the cmos with the jumper and no luck. It goes to 3.32ghz after i clear the cmos or take the battery out, but now when I start up the damn thing turns off on me. I can get to the bios screen and when I try to load the performance defaults it turns off. I dont think its the cpu because its not old at all, and normally if the cpu was bad it wouldnt get to bios screen.The mobo is year or less old so i dont think it would be the mobo. Could it be the PSU? Its 250w lol but I dont have many drives or anything that uses much power. I need to fix this because its annoying as hell. Any help would be appreciated as always.
