    Default Re: New system has boot loops

    OK, thanks so much for all the help. Keeping the CMOS pins jumpered for 10 minutes did the trick. Now I have a question about what caused my CMOS to become corrupted enough that the boot loops started. It seems as though if I shutdown normally, there is no problem. But if I have to do a hard power off with the on/off switch on the PC while it is running, that's when I get this problem. Anyone have any ideas on why this would happen and what I could do to prevent it in the future besides only powering down via the OS? I've not had this problem before with doing hard power offs on other PCs I've owned. Thanks for any help.

    No that was another system I am working on.

    From my experience I had this problem with older bios versions but only happened while O.Cing and not have it stable enough and it would bsod and it would reboot on its own into the boot loop. I would just click the switch on back of my psu wait 10-20 seconds press the power button on front of case then turn switch back on psu then turn computer back on. But with the older bios's this would happen with what was a stable O.C and have to restart computer because of a software install. But I have yet have to use the jumpers to clear bios on this board I think. But since updateding to F10e I think i had 1 boot loop but I was pushing 4.5ghz . I have been reading a few post people having trouble with F10e but its been smooth sailing for me the most stable out of all of them. I cant remember if you have ver 1.1 of the board or 1.6 if you have 1.6 the latest bios would be FDa. might give that a try if you are still having reboot problems in future.

    Glad to hear you got both systems up and working.

    Agreed with Acebmxer. If I do a hard power off I sometimes encounter looping as well. Rather than reset the CMOS I just turn off the PSU at the back and hold the power button in for 20-30 seconds.

    It's likely that your CMOS settings weren't corrupt as such, just that something had been set by the board that was causing an issue, causing the whole thing to need resetting. Jumping the clear pins did this and allowed you to boot again.

    Did you remember to load optimized defaults, then save and exit before going back into the BIOS to enter/load your custom settings? If you didn't I recommend doing this ASAP.

    The boot looping is something that can sometimes be fixed with voltage adjustments, such as slightly more Vcore, MCH core (or less MCH core), CPU termination, PLL or a change in CPU or MCH reference voltages. Alot of the time though it's just one of those things that seem to happen for no reason. It happens on my syatem, and as you can see from my sig, the rig is pretty stable.

    Things are steady for the last couple days, but I've not tried a hard power down yet. Thanks for suggesting the alternate ways of fixing the boot loops so I don't have to go inside the case and jumper CMOS--that is really a pain.

    I'm not sure if anyone else has already suggested this, but in case you do need to clear the CMOS again, you can connect the case reset button to the clear CMOS pins. This way you can just hold reset to clear it rather than have to open the case. just be careful not to accidentally push it while the PC is on.
