Preferred Solution: Q35 BIOS CMOS BAD ERROR

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)



Since you can get intot he BIOS I would recommend setting it to defaults (usually by pressing F9), then update the date and time, then saving and exiting to see if that fixes it.

Okay I recently tried to update my bios on a GA-K8NS mobo. I used the bios update program that gigabyte has so I am pretty sure that I installed the correct update. After the install the system restarted and then said CMOS error press F10 to continue or DEL to enter setup. I entered setup and flashed the bios to the original settings (I made a copy to a floppy before update). The system restarted fine with the old bios. What is this error and how do I fix it?

OK....got the CMOS error fixed and BIOS is updated. I installed a hardware monitor that came with the mobo and it keeps saying "warning sys fan rpm."
I looked at the fan speeds and they are:
SYS FAN = 1739 RPM
CPU FAN = 3750 RPM
CPU temp = 40C
I am new at all of this and do not know what to do. Does everything look alright? Is the program just screwed up? If there is something wrong how should I fix it?
Thanks for all the help...

I only recieved this RL85 yesterday. I did a clean install of windows 10 on a 2nd HDD and the main 1TB HDD to be used as storage. All was working well. I installed all the drivers. Then installed the BIOS update from the website.This worked fine and i shut down the machine. Since then my BIOS is showing 0 for the RAM and any changes I try to make to the BIOS won't save! Have I just been really unlucky and got a faulty RAM slot or CMOS chip or is this a BIOS issue? I looked at reflashing the older BIOS but I can't do this as I can even choose a DOS bootable USB because I can't save any changes in the BIOS! I have contacted ACER for a repair as I suspect a hardware failure but I would be grateful if there is a better solution. Due to the design it isn't like I can take the RAM stick out to check it!

I am experiencing 'weird happenings' with my computers BIOS.

I bought my computer from Holly System, it has a Chaintech motherboard and phoenix-AwardBios - Bios. I cannot refer the problem i have too Holly System because they do not exist anymore.

Two or so years after purchasing my computer, i turned my computer on and was hit with an error message on boot, 'CMOS Checksum error - Defaults loaded', when the computer fully loaded up i noticed the time and date had changed, the date had gone back to 2002 and the time 23:00.

Forever onwards i just got used to turning the computer on being given the CMOS error and then repeatedly setting the computers time and date. Eventually i decided to look into the problem. I found some articles saying you should replace the CMOS battery if you are getting the CMOS Checksum error. I replaced the battery, for a few days the computer was fine, until i was hit with the error once again, i then started noticing things.

Obviously the new battery had some effect as it removed the problem for a couple of days, when the error came back and the com... Read more

Those are not jumpers If you want to reset BIOS settings, you could just unplug power(cord off the PSU), discharge power by pressing the power button for 10 secs, then take the CMOS battery off, and wait for half an hour or so. Put those wires back their place. Refer to motherboard manual...

Hello to whomever will read this.
The device in question is a Sansui Lifepad (Etab WIB 700) running Windows 8.1 (not mobile, just full-on Windows)
I noticed it had an issue with it's graphics adapter not being able to display in its native resolution which cause incorrect calibration of the touch screen.
I (foolishly) went into the BIOS and disabled the internal VGA and now it boots up completely blank, no bootup logo at all. I can tell it's powering on because after a few minutes the back starts to warm up showing usage.
I encountered a laptop some months ago whose VGA had also been disabled. For that laptop we disconnected the battery and removed the CMOS and that managed to reset the BIOS.
The problem is the tablet has no CMOS and disconnecting the main battery has yielded no results.
In trying to connect it to an external monitor, the device does not have any output port (micro HDMI) at all.
Is there a way to reset the BIOS?

I have watched several videos on how to do this and some say just remove the silver battery on your MB for 5 minutes and then replace it and reboot the computer.

Other videos say, locate the silver battery on your MB and right next to it you should see a very small jumper. Just pull straight up on the jumper to remove it and wait a few minutes and then replace the jumper to the original position you found it in and reboot the computer.

And yet other videos say to simply go into your BIOS by tapping a special key as your computer is booting-up and that will allow you to enter the BIOS settings and select the option that says "Restore you BIOS to it's original settings" and then select Save and Exit.

My question is this: do all of these methods accomplish the same thing.

BTW, I don't need to do this right now but would like to learn how to do this if I would need to some day. Just trying to learn some of this stuff.

Hi there,
my Dad's got a problem with his pc. It all started with the computer just being taken downstairs for a day. When my brothers put it upstaits again, suddenly strange things started to happen: First, there was an audio problem and an error message occured which said that the audio driver is bad. we didn't really care cause my dad didnt need sound, but before we moved the pc everything worked fine. to make it short, i'll just write down keyowrds.
- the pc didn't even boot when my dad wnated to use the pc some hours later
-> stopped after having detected the masters and slaves, freezing
- next time we tried to boot: FD failure - floppy drive, right?
-> all the cables and stuff were checked - everything was fine.
- reboot - now a CMOS failure, floppy was alright. how come?!
- we never reached the windows xp boot screen.
- i reseted bios by switching the jumpers
-> error message: fan not running, so i wanted to config Bios, but after pressing Del, it even said go->setup but it froze again and i didnt see no bios at all ... and i tired a thousand times to open bios but nothing happened and in most cases, the FD failure occured again

two days after...:

I've seen a few problems like mine on the boards but never a satisfactory resolution. My problem started with a frozen screen. I did have a few windows open and i was listening to music and surfing at the time. Upon restart case light came on, M/B power light came on, fans on psu, cpu and graphics card all spun up as well as hard drive, but no post beep. Long story short is that I have done everything recommended on various forums, like resetting the Cmos via the jumpers, taking out the CMOS battery, leaving the CMOS battery out overnight, new CMOS battery, changing the PSU etc. and am now at the stage where I have the M/B stripped out of the case on the workbench with just the psu, one stick of memory, Graphics card, Hard drive, mouse and keyboard. Strange thing is computer WILL post with default Bios settings when CMOS battery removed, go through bios setup routine, launch Windows and run perfectly normally. But as soon as I put the battery back, nothing, no post beep, nothing, just spinning fans and no display. Has the Bios Chip got corrupted? The battery clip does look firmly soldered to the M/B and is not bent. I am at a loss. Can't RMA the M/B as its an Ebay job. All the Caps look sound. Is it worth replacing the BIOS chip as they're fairly cheap or is the M/B toast?? Does anyone know anything elseI can try??

The problem now the PC can't go through BIOS, the fan is spinning and green light is on but no beep sound.
Don't know if the battery problem or the mobo already dead
Thanks for any help

A:PC won't go to BIOS, after removing CMOS battery

CMOS only retains BIOS settings for a few seconds after the battery is removed. 24 hours is just insane overkill.

Also, on most semi-modern machines, the password isn't stored in volatile memory and as such will never be "reset" using that method - There will be a jumper on the motherboard to specifically erase the password. You should search for that motherboard on the internet and fine the manual for it.

As for the machine not POST'ing anymore, I would suggest that you moved a jumper or that something is not seated right. Double-check that the ram, cpu, video card, any other peripherals, cables, and battery are all seated properly. If in doubt, remove them and re-seat them. Find the manual for that motherboard online and go through it, checking all the jumpers on the motherboard to make sure they are in the correct positions.

In the process of installing windows 7 Professional I discovered that I could not get into the BIOS or setup because it was password protected. I?ve tried a number of things including installing HP ProtectTools Security stuff and it seems that all that has done is to create more login passwords. I can now get into setup but as a user but not as an administrator and so I cannot change password. There is also another screen that shows up where I must enter a password and I?m not sure if that?s happening because of the HP Protect Tools that I installed and then removed or because of something in the BIOS. I?ve uninstalled HP Protect Tools and reinstall windows 7 and I still see both password screens. I attempted to update the BIOS using a file downloaded from the HP support website but cannot because I don?t know the admin password for access the BIOS.

Hello Everyone,

I'm building a new computer here, and i'm using a previously owned mobo. I'm having an issue getting pass the BIOS spalsh screen and into the boot menu so i could bootup and install windows.

I have no beeps at all. every component of this computer is brand new except for the motherboard.

I try to go into the setup and i get the dialogue, "Entering Setup..." but it just stays frozen like that.

I know i have to Clear CMOS and i removed the CMOS battery for almost 3 days and nothing at all. i cannot find the CMOS jumper. i see a jumper near the CMOS battery but it isnt labeled clr cmos. i removed it and put it on the 2nd and 3rd pin and the machine doesnt even turn on, but when i locate it back to the 1st and 2nd pin, it turns on perfectly fine, but i still cannot get past the startup screen

the screen i cannot get past looks similar to the image below.

Any help will be highly appreciated!
Thanks in Advance!

Hi everyone,
I'm trying to change the settings in BIOS CMOS, but when I arrow to Load Optimized Defaults and try to save by hitting F10 and I choose Y to save and exit there is no way out except to hit enter but the settings don't change.

I posted some time ago about trying to fix a problem with this computer for my friend because when it booted up it showed white text on a black screen. I think that is the MBR but not sure. It shows on the first page F1 and del and sometimes loads a lot of what look like drivers but I am not sure, now it's seems to just show the first page with F1 and de. I hit F1 anf it loads to Windows. I brought the computer back to my place to try and fix this issue because my friend said that sometimes the screen just goes black and she can't do anything. That hasn't happened to me in almost a week when I turn it on. However, I thought a repair would do the trick but haven't tried yet. I am wondering if I change the boot menu in BIOS it might get rid of the first screen for her before Windows loads. I just thought before I do the repair I should maybe try the BIOS CMOS settings but can't change anything there.

Also, I know now that I have to uninstall IE8 before doing a repair but can't seem to find an answer about "do I also delete the IE updates in add/remove " or do they automatically go?. Do I have to do anything else before the repair, like uninstalling IE6 if it is there and if not do I install I... Read more

Hey. So, I'm running a 6 year-old desktop that has crapped out on me again. It was a custom job by cyberpowerpc, and I don't remember too much about it. One day, it crashed. I have the above screen whenever I startup, after the initial boot menu comes up. I managed to fix it by repairing the memory with some cleaner, but that was a year ago and I have completely forgotten exactly what I did. I know I agonized over it for weeks, because I'm a flat broke loser with major depression and anxiety issues that are so bad I can't leave the house. Thing's basically my lifeline.

Anyway, I really need a bunch of the files on it soon for important personal reasons. I can access the CMOS screen, but all the fiddling I've done with it doesn't do much. I tried removing the CMOS battery to reset the memory that way, but it didn't work. Honestly, that's probably not the real problem at its core, but I just need a quick solution, enough to access what files I have left, pull them off, and transfer them to a new laptop.

An actual fix would be preferable. I know that I haven't given much information, but I'm not entirely sure what would be relevant to share. I'm really only asking here as a semi-last resort. Solutions I've tried from searching the internets haven't been helpful, and have basically what led me to the CMOS/BIOS path. Since "repairing" it worked before, I'm inclined to think it's related, bu... Read more

Appreciate some assistance.

On a GMB-P57IPS-V0 mainboard, JP4 identifies the system ROM selection. Jumpers 1-2= 5V Flash EPROM (currently set), and 3-4=12V Flash EPROM. Is this the same jumper used to clear CMOS? How do you go about clearing the CMOS settings for this board?

There is a lithium battery above the AWARD BIOS. Is removing that battery the way to clearing the CMOS?

The reason for asking is that the CMOS/BIOS for this board is password protected. It is a used board, and there is no way of finding out where it came from or its password. Needless to say, need to get into the setup to establish values, etc. Hope there is a way to get rid of the password and get into the settings.

Any suggestions are welcome.

I have a HP Pav 13 x360 Win 10. The main battery has the CMOS included inside it or it doesnt have one, I have heard both. The error persists with the battery uninstalled, using only AC power.

It all started with plugged in, not charging. Then got CMOS checksum is in invalid on startup. Changed battery 3 times (twice from HP and once from me)

Gave up and set it aside for months. Took it to a tech who could not find anything wrong with it. It was charging normally and told me it just needed to be at 0 for a while and should work fine. It booted with no error.

It is now showing the error again but is charging. Could it be a motherboard error if it happens without a CMOS? I have updated it and flashed the BIOS.

Any help is appreciated

Hey everyone...it appears I'm having some issues with a slow clock.  I have an XPS M1330.  Initially, it would fall behind a few hours each day, INCLUDING the BIOS time.  Also I noticed frequent Wi-Fi disconnections, as well as when I would shut down the laptop, it would not completely shut down.  It would go into what I believe would be an "idle" state, showing the blue power LED still being lit.  I would have to then manually shut down the laptop by holding the power button.  That was the only way of getting it out of the so-called "idle" state.  So first thing I decided to try was to replace the CMOS battery which was the first suggestion.  After replacing the CMOS battery, I got about 2 weeks of flawless performance; no slow clock, and no powering off issues.  Now, the clock is running slow again and I can't seem to figure out why.  I updated to the latest BIOS (A14 I believe), which seemed to work for about a day, now it's back to being slow again.  It is not shutting down properly either.  When I check the BIOS time, it is also incorrect.  I'm not sure if this a motherboard issue or what but any suggestions or ideas would be great.

I wanted to bump this because I really want to see if anyone has any idea or answers as to what this could be or how to fix it so I can save myself some money and not buy a new motherboard.

Hello 3bdom7sn,   Welcome to HP Support Forum and we are glad to assist you. This is to inform you that all HP Business Notebooks such as Probooks  or Elitebooks have more stringent security than consumer models infact they don't produce 'halt codes', the password cannot be derived from the Serial Number and thecode is stored in non-volatile memory so removing the RTC cell will not reset the password in this case. Please have a look at this link. http://forums.mydigitallife.info/threads/49497-HP-Probook-Elitebook-BIOS-Password-Reset-Utility Replace the BIOS chiphttp://www.ebay.com/itm/HP-Elitebook-8470p-8470w-8570p-8570w-8770w-Programmed-Bios-Chip-No-Password-... Please Contact HP Business Notebook support they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.  When talking to the HP rep ask them to escalate your service request.  Hope this helps, for any further queries reply to the post and feel free to join us again  **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,GBL84I am not an HP Employee

Hello guys,
I have 60 GB maxtor hard drive. it had two primary partitions with dual boot,
one is WinME and the other was XP. it had lot of unwanted programs from my friend and was not working well.
my friend had assembled it with AMD 1.8 GhZ, 512 MB RAM.

I bought a new XP pro software and decided to have a clean install.
used GDISK( similar to FDISK) to delete all partitions.
then i put the XP CD to create partition and load XP, it said no HDD found.

i did not open the box nor distrub the box.
i did the following in the sequence i have stated.
I copied all the data files into CD.
then i put the GDISK to delete all partitions.
then put the XP cd and boot from CD,
XP setup comes up and it is unable to identify the HDD, so everything else
stops. everything was working before suddenly after delete of partitions,
HDD could not be detected by BIOS.

then i looked into setup while booting,
the CMOS standard does not identify HDD.
it had the following identified in SETUP - CMOS standard
Primary master: DVD rom - ( i set this in AUTO and press ENTER it identifies
Primary Slave: no installed ( i set this to AUTO and press ENTER- it says
not installed.
Secondary master: CD ROM
Secondary slave: not installed.

it detects Floppy drive.

any ideas..
thanks in advance..

Hi all i have problem with my computer its 2 months old and now i reseted CMOS from the jumper.
All lights and fans start up but BIOS is not posting and no picture is coming to screen

AMD FX-4350
Gigabyte 760gtx OC 4gb
8gb Kingston 1600 MHz
Asus m5a97 2.0
600w LC power psu

I have tried with 1 ram stick and yesterday I ran memtest86 about 16h with no errors so its not ram.
I tried GPU on different slot.
Removed all devices from PC.
Checked that all connections are firmly attached.

Is there possibility that CPU would be dead because I ran prime95
and almost in 1 min I got bsod and I have getting these bsods for almost month (Bsod 0x8000000000000002 on idle)

I have a 7-8 year old computer, Gigabyte ALi Aladdin GA 5AA motherboard, AMD K6 3D processor, Award AMIBIOS CA 1996.
Windows 98SE

Hard drive (Primary Master)
CD ROM (Primary Slave)
HP CD RW burner (Secondary Master).

About 2 months ago the computer froze & on restart didn't detect the HD. I found in BIOS that the setting had changed from Auto Detect to User, so changed it back to Auto - problem solved. For the moment.

About 2 weeks ago started getting the same problem, this time with the CD RW - 3 times in the one night the computer froze, and each time I found the BIOS reporting it as "Not Installed" - changed it to "CD ROM" and it was found again on restart. After that things were OK until again this week...

Computer freezing again resulted in a restart not finding the CD RW again (in BIOS). I changed this back to "CD ROM" from "Not installed" but this time after saving the setting & continuing the boot, the CD ROM setting was not saved - couldn't seem to get it to stick.

Worse, the HD was again reporting as "Disabled". However, an option to press F1 or F2 (?) to resume resulted in the HD being detected with the manual user setting, and windows started up. Each time I tried setting the IDD auto detect to "Auto" it would go through the same boot up sequence, telling me that it couldn't be autodetected, but booted manually anyway, and each time I went back to BIOS it had changed back to th...

I would like to set my motherboard back to it's original bios config. I would like to clear the cmos. I have a msi K8T neo2 version 6202E. I want to clear becuase I was messing with the two drives I have and I slowed down my pc. Boots are slow, very slow since the fiddling. I know it's not the drives becuase I formated and cleared them. If I jump the JBAT1, will I loose anything, or will it set to factory and I have to load drivers again.( which I want)
Thank you

A:set motherboard bios cmos to factory default.

If you take the CMOS battery out for 15mins that should clear all the BIOS settings and therefore set it to factory settings,

I read a post on reddit https://www.reddit.com/r/DotA2/comments/8fb7am/check_your_ram_settings_for_free_fps_benchmarks/about getting extra FPS by making sure your ram runs at it's max speed. I checked using CPU-Z and my RAM timimgs were 6-6-6-18 and 534.6MHz x2 it was running at instead of the advertised 9-9-9-28 and 800 MHz x2.

The post said to go into the BIOS and change the setting to "XMP" or "DOCP". I didn't find these and so I attempted to manually change the settings, by setting the frequencies to 9-9-9-28.

After my computer was stuck in a boot loop. I could not get past the windows logo screen, and if I waited I would be prompted with an option to repair my system, which if selected would show a loading bar for a while before giving me a blue screen. After many attempts to get out of the boot loops by reverting the changes to my BIOS, and trying the "fail-safe" recommended settings to no avail, I reset the CMOS.

After starting up, I am prompted with F1 to fix my BIOS settings or F2 to load defaults and continue.
F2 leads to a boot loop, and F1, with any changes (even just setting the date and time, or saving while making NO changes) t... Read more

A:Strange PC issues after BIOS changes / CMOS reset

The Intel Core i7-960 3.20 GHz quad core processor in your computer supports a maximum DDR3 speed of 1066 MHz.
That's why the CPU-Z app shows a DDR3 speed of 534 MHz X 2 instead of 800 MHz X 2.
You cannot force RAM modules to run at a speed faster than what the processor supports.

Someone else here will need to address your BIOS/CMOS issue.
