Date keeps changing - ASRock H110M-HDS

I would ordinarily recommend a CMOS clear but removing the battery already did that so the next step is to update the BIOS to the latest version. It sounds like either an RTC (real time clock) issue or there is some software messing with it.

That is worth trying, you should be able to change to the earlier version.

If the earlier version causes the problem to disappear, it seems the new version is the cause.

The problem happens every time the PC comes out of sleep mode. When digging through webpages online, I found someone who had the same problem with their HP laptop. So every time you wake the computer up, the date (not the time) advances. We turned off the sleep setting in Windows 7 (set sleep to "never"), and the date problem was fixed. It's not a total win since the problem still exists underneath, but it's better than troubleshooting the hardware.

So you mean you don't let the PC ever enter Sleep mode? Or is that no Sleep mode automatically, and entering Sleep mode manually does not cause this date problem?

All I know is, over the years with different versions of Windows and various hardware and software, Windows Sleep remains a problem. The problems it has are multiple and of all kinds.

I stopped using Sleep with some older hardware (Asus P67 board) and Windows 7, since upon waking from Sleep, the video source would not work, black screen. Restart the PC, video was back.

I accidentally forgot to disable Sleep recently in Windows 10 on my ASRock X99 board system, and found the PC in Sleep mode when I walked away for a while. It woke up fine, no other weird side affects. Tried it on my ASRock Z170 board system, works fine too, so I'm back to using Sleep again.

Waking from Sleep requires many things to be restored that are not automatically done by the OS itself, apparently. So the mother board manufactures are stuck helping Microsoft with their Sleep feature. Too bad the fixes are not simple and obvious.

I keep having problems where my mouse cursor disappears after turning on the monitor. Have to keep clicking blind around the screen for 20sec to get the thing back. Appears to be a common problem with Win10. I think it might be sleep related as well.

I doubt manual or automatically entering Sleep makes any difference.

What type of mouse? Wireless? That's what I use. Mostly MSoft mice, I figure they ought to get things right with their OS and hardware.

I'm not having that problem waking from Sleep at all. If I do lose the mouse somehow, I'll turn off the mouse power switch, and then on again. If that doesn't do it, I remove the wireless transmitter from the USB port with the mouse power off. Plug the transmitter in again, and turn on the mouse.

If that doesn't work, it's restart time.

My 2cents lie with this being a BIOS programming issue ASRock needs to look at.

OP, did you try each available BIOS revision on your boards download pages, and if so do one make any difference?
