Assorted error screens... CMOS issue? Possession by demons?

Hi guys,

Been having some issues with the PC I built earlier this year. First, my specs:

OS: Windows 7 Home Premium 64-bit
Motherboard: MSI Z77 MPower
CPU: Intel Core i5-3570K
Memory: Corsair Vengeance 8 GB
GPU: MSI N680 (GeForce GTX 680)
PSU: Seasonic SS-660XP2
Boot drive: SanDisk Extreme SDSSDX-240G-G25
Add'l drive: Western Digital WD Black WD1002FAEX

For the past several months, I've been getting the following screen upon booting up. It appears most of the time, but not 100% of the time (actually, I think it might only appear when I turn the power supply off after shutting down. If I shut down but leave the power supply on, I'm fairly certain the screen doesn't appear upon the next boot). Not sure if I can embed here so I've linked to my Photobucket account:

As you can see, it appears to be a summary of my components followed by the message "All settings were reset to default values. | Press F1 to run setup | Press F2 to Continue"

I've read that this could happen when the CMOS battery is reset, but I've never reset the battery.

Strange screen #2: this one appears when I wake my computer up from sleeping. Upon waking, the computer will start up (lights blinking, fans running, etc.) for just under a second, then abruptly shut down; after a few beats, it will start up again and then shut down; a few more beats and it starts up for real, except instead of "waking" and returning me to my desktop, it gives me this screen:

In case you can't link to the picture, the message reads: "Your system's memory configuration has changed since it entered hibernation. If you proceed, the data needed to resume from hibernation will be lost. To preserve this data, turn off the system power, restore the original memory configuration, and then reboot the system. Otherwise, press <ENTER> to delete restoration data and proceed to system boot menu."

I hit enter, and my computer boots up and takes me to the desktop. I've never done anything to my computer's RAM since building the thing in January.

And finally, the third strange screen I've encountered. I've only seen this one once, four days ago:

Unfortunately, I cannot remember what I was doing that prompted this screen (booting up? Waking the computer from sleep?). Reprinting the text on the screen:

"Checking file system on C: | The type of the file system is NTFS. | One of your disks needs to be checked for consistency. You may cancel the disk check, but it is strongly recommended that you continue."

I then instructed it to "check the disk" and it ran through a series of checks ("CHKDSK is verifying files, CHKDSK is verifying indexes, CHKDSK is verifying security descriptors"). Not sure what the heck that was about.

One last thing: this week, I noticed that the Windows date and time are often out of sync when I boot the computer up. I suspect my CMOS may be dying. Really not looking forward to having to swap out the motherboard, so I'm hoping these things all relate to some other easily fixable issue.

Thanks so much for your help.

  1. Best answer
    The first error message and the date/time issue could be a sign that the CMOS battery is dying. It is usually just a regular CR2032 coin cell battery. If your memory settings have to be adjusted for some reason, such as to get it to run at its correct speed, that could be affected by a failing battery, which could explain your second error message.

    As for the third error message, that usually comes about if the computer isn't shut down correctly.

  2. Thanks Casey. I just did some Googling and found this bit of advice: "If your computer is losing its time or date settings... first try leaving the computer on for 24 hours. In some cases this can charge the battery and resolve your issue. This often resolves CMOS battery related issues when a computer has been left off for several months."

    I did in fact recently leave my computer off for several months, as I was living out of state for the summer. When I returned is exactly when these issues started cropping up. I'm going to leave the computer on for 24 hours as suggested and see if that helps before trying to mess around with replacing the CMOS battery. Thanks again.
  3. That would work if your battery is rechargeable. Most CMOS backup batteries (including the standard CR2032) are not rechargeable.
