Accidentally hit the CLR CMOS button.

I accidentally hit the CLR CMOS button when hooking up my monitor cable. When I powered on my PC, I got the Windows 10 message that said my PC ran into a problem and would restart. After the auto restart, got a second message saying with two options- shut down or Advanced options. I tried the automatic repair under the advanced options button but that didn't work either. I then selected another option under the advanced menu, to do a system restore to a previous restore point (1 week earlier). The system restore completed, but during the restart I ended up at the same place I started. Can someone help.

In at least some cases I am aware of...CLR CMOS resets the BIOS to the defaults.

If you had changes in your BIOS to accommodate something...they also went to default.

I think you need to go into your BIOS and change something back to the way it was.

As far as what that is....I don't know...but I would at least be going in there and looking around and seeing what I could see.

Question from johnna.mckinnon : "Accidentally hit the CLR CMOS button."



Windows can't fix what is basically an incorrect setting (or settings) in the BIOS configuration.

Using CLR CMOS causes the BIOS to reset/revert to it's factory defaults, thereby losing any custom settings you may have made. Neither Windows nor System Restore can rectify this.

You therefore need to go in to BIOS Setup and restore those settings to what they were before the reset.

It's most likely related to the hard drive configuration settings.
 


This has me a bit curious, how were you hooking up a monitor cable that you managed to hit a tiny button in the middle of a motherboard during the process?
