PCI USB expansion card causes CMOS error

Q: PCI USB expansion card causes CMOS error

The USB expansion card is a Via Vectro vt USB card PCI expansion causes CMOS error that I scavenged from an old build whose motherboard fried when the cooling fan suddenly stopped working it was an OLD build CPU couldn't shut off automatically when the temp got too high and I know most boards have been able to do that for about years It was tested working in another PC emachines T its older than my little sister but it still works so I use it to test stuff I upgraded it from mb to mb of RAM which can comfortably run Windows with aero turned off although I do dual boot with Android x because PCI USB expansion card causes CMOS error why not so I PCI USB expansion card causes CMOS error know the card isn't broken The PC I'm trying to install it in PCI USB expansion card causes CMOS error is a Lenovo Thinkserver TS which I upgraded to gb RAM ECC of course I know I don't need enterprise grade stuff but I hate blue screens and corrupted files and put a TB Seagate Barracuda in When I put the USB expansion card into the PCI slot and press the power button it gives me a CMOS error beeps which means the card is incompatible with the BIOS This doesn't make sense to me because PCI-e the Lenovo is supposed to be software backwards compatible with PCI the expansion card How do I get it to work EDIT Its a full-size pcie so its not like I'm trying to stick a big card into a tiny hole

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/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: PCI USB expansion card causes CMOS error

Ah... you've transported us all back to the bad old days of the IRQ error (Interrupt ReQuest).

At that time there were only 15 IRQs and it was quite common to need to manually change a new device's IRQ position so that it did not conflict with another device, freezing the system.

Modern PCs use the APIC system which greatly expands the number of IRQs and reduces the possibility of conflicts.
But this system relies on Plug-and-Play devices to automatically configure the IRQs. That is why the vast majority of people reading this will have never heard of it.

Can you get into your BIOS settings with this card installed?

You could try the card in a different PCI slot if you have one. That would sometimes change the IRQ in older systems.

You might also try doing a ClearCMOS procedure with the card plugged in. That may force the system to reassign IRQs for all the P&P devices and free up whatever IRQ that old card insists it has to have.

There's not much magic in USB expansion cards. The card you mention will work fine as long as your motherboard has an accessible PCI-e X1 slot

What expansion card can I use? I have the Acer ATC-605-UR51 desktop AKA the TC-605. I seem to have two expansion slots inside. One is smaller, and I used it for this USB 3.0 card. One is larger. I wanted to have some USB 2.0 ports and purchase this card, but it did not fit. What can I buy? Thanks!!!!

The PCI card (Adaptec 29160N RAID) is 32-bit but the expansion slot on the motherboard (Super Micro P4DPR-6GM+) is 64-bit 66MHz PCI (3.3V). The card's POST doesn't show up during boot. Is this because it's 32-bit and the slot is 64-bit?

I upgraded the memory in a computer, booted up the computer and new memory was accepted. I shut down the computer and installed an SMC network card in a computer. I went to boot the computer up and I got three high pitched beeps, followed by a pause, then a low tone noise. Everything boots up except the monitor will not come on. I have taken out the additional memory I put in, have taken this computer completely apart and reassembled it and when I boot it up I still get the beeps and the monitor will not respond. I have double checked all the jumpers. Any clue to what this could be?
 

A:Installed Expansion Card

From that pattern, it sounds like a video problem.
Might be the Video Cards is loose in the socket. Take it out and try reinstalling it again. Also, check to see if there is any dirt/etc. on the contacts. An old trick is to use a pencil eraser to clean the contacts. Likewise, blow out any dust/etc. in system.

Also, does it work without the SMC network card installed?

Another possibility is that it got a static charge when you were installing the network card.If that happened, the only thing that you can do is replace it.

Hope this helps

@Dr_Saiful?, welcome to the forum. Here is the Maintenance and Service Guide for the computer.  Beginning on Page 26 you will find the Workstation Specifications.  In the specs it says that two video cards can be used as long as the required wattage is no more than 150W.  I suspect that you may be exceeding the wattage of your power supply unit (PSU). Please click the Thumbs up + button if I have helped you and click Accept as Solution if your problem is solved.

A:CMOS error

Hi

Usually if you get the "C-MOS checksum error-defalts loaded" error message when turning on your PC it is because the CMOS battery is flat or your motherboard is faulty. However it is not very often that a faulty motherboard is the cause.

Try replacing the battery.

My secondary rig keeps showing a CMOS error on boot, but only if it has been shutdown. On a restart or at desktop, there is no problem, and SpeedFan shows the Vbat at 3.10v, which is normally sufficient to indicate that the battery is okay.

If I understand, the PS provides current to maintain the battery when powered on, so that tends to indicate that the battery is bad, regardless of what SpeedFan says, but I'm wondering if there is something that I'm overlooking?

Perhaps it is a BIOS issue. Try updating your BIOS to the latest version.

I am using ASUS A7V266-E motherboard with BIOS 1006, AMD 1800+ processor. The battery is new. I have reset RTC as explained in the manual. Now I get a message “CMOS checksum error – Default loaded” every time whenever I switch on mains power. The BIOS setup, time, date information types are not saved at all. I understand through on line help that, the method described to reset / clear CMOS in the manual is wrong! What should I do to resolve the problem?

I installed a new Motherboard (ELITEGROUP PT800CE-A) and used my good Intel Pent 4 1.7G 533 FSB Processor. At turn on it recognized the memory,cpu and both master and slave units. However, I received this message on screen.
CMOS Checksum error- Defaults loaded. Warning:CPU has been changed or CPU ratio fail. Please re enter CPU settings in CMOS setup and remember to save before quit. If I change anything on the clock time(100 to132) or ratio(10 to 24) the computer will not turn on or continue from the setup. In the original setting of 100 and 10 the computer will not continue from setup. So it seems evident I have to use the clock of 100 whitch is selected in the automatic select jumper setting, but, what is the ratio setting or what else is there I must change? HELP!

I just replaced my old MSI/AMD motherboard and CPU and I may have made a mistake by switching over to an Intel CPU and Biostar motherboard, I'm not sure. But, when I boot up the computer it gives me an error message and stops the boot-up process. The error is

CMOS checksum error - defaults loaded. CPU has been changed, ratios are off. Change CMOS.

I've tried going into BIOS to change the FSB and anything else that might be causing this error, but I can't find what it might be. And, once I go into BIOS, the computer tries to start normally but just goes into a continuous loop of restarting itself. I've tried for several hours to find a solution on Biostar and intel as well as on here and haven't been able to find anything, please help!

Recently whenever I unplug my computer and plug it back in, or whenever the power to my house goes out, it gives me a CMOS checksum error at boot up and resets the system clock and all the bios settings to defaults.

I read about the error and it seemed these errors are usually caused by a dead system board battery, but the symptoms for that sound like it does it every time you start your computer, which isn't the case for me.

Is it likely to be a dead system battery? Are they easy to replace?
Thanks!

A:CMOS Checksum Error

Yes this sounds like your issue and no their not hard to replace.

After opening the side of your case, look for something about the size and shape of a quarter mounted on the system board. Usually the battery sits under a tight clip and you can remove it by lifting the clip. Sometimes they snap into a socket and you have to push a little tab to release them. Most batteries are the CR2032. You can purchase these at a Walmart or Radio Shack.

After replacing the battery, start up your computer and press the appropriate key to enter the BIOS setup screen. (Usually it's the DELETE or INSERT key. Watch the screen for instructions or consult your manual.)

Set the system clock to the correct time, then save and exit. If your computer works normally now, you're all done. If it doesn't recognize one or more hard drives, go back into Setup and look for the hard drive "Auto config" or similar. Sorry, but every BIOS is different, so it's impossible to give more detailed instructions.

Hello all,
 
I was trying to install Windows 7 Starter from a bootable USB and I got this same error. Upon reading this threat, I found the solution. In the boot-up list in your BIOS menu, you have to remove the Atheros boot agent / LAN from the list.
It will then boot to whichever boot-ready device you've got.

Sounds as though that motherboard mught be shot to pieces. However, it's unusual for PS2 keyboards not to obliged at least with the Delete key at boottime. There are a few motherboards out there with keyboard and mouse sockets reversed - that it, mouse on the left as you face the back. Could this be one such, and are you not bothering to look when you plug in?

That said, "CPU was changed" is a strange message to see unless, of course, you have changed it. My money is still on a dud board.

I've read on the internet that it my computer battery running out. If it is, how can i make sure because i don't want to get a new battery for no reason. I'm hoping it's something like a faulty setting i've made, or a virus as i can remove it without having to spend money.

A:CMOS CheckSum Error...

The solution is to replace your battery in your comp.

I jumped when I read the title to your post! Oh boy! I'm actually get to use my former skills as an embedded system developer again! I used to be a high tech engineer and switched to being a comp tech during the high tech collapse.

Anyhow, CMOS is a type of memory. It stores values/settings for your BIOS between sessions. When the BIOS starts up it reads them from CMOS and saves them when it shuts down (or whenever you explicitedly save settings within BIOS) Now, CMOS is volatile memory, meaning that it's contents will be lost in the absence of power. That's why your comp has a battery. The battery kicks in when you turn off the power to the comp and recharges when you power on. But over time, batteries can lose their capacity, hence, your CMOS loses it's contents between sessions. The BIOS can only check the checksum of the CMOS contents to determine if something is wrong with the CMOS but exactly what caused the checksum failure, it can't tell. What tipped me off was that everything returns to default which means all the CMOS data was lost. That usually means the battery is dead.

First of all, this is such a wonderful and helpful website. You all rock! Just by reading posts, I have received so much help/guidance. THANKS

Now, onto the reason why I'm going nuts. I am not an expert, but I have always considered myself fairly proficient in fixing computer problems, until now. I have a Elite K7SEM motherboard, a little less than 2 years old, and a CMOS Checksum Error that will not go away, despite changing the battery, clearing the jumper settings, and going over the BIOS inch by inch. My question is, besides resetting the time everytime I turn the computer on, can I go on indefinitely like this? Or, will the motherboard finally say enough is enough and just shut down on me?

Thank you
 

A:CMOS Checksum Error

You can run a motherboard without a battery all together. You may get less performance out of the system because the BIOS settings will be at default levels but it should work.

Now, its possible that the replacement battery is no good, I had it happen to me before. You can also examine the battery holder's contacts to make sure they aren't the problem. The jumper for clearing the CMOS must be set for Normal not clear, And you must enter the BIOS, load the defaults and adjust the settings to the desired, then SAVE and EXIT. Also if you've added any new hardware you may wish to remove it or check for BIOS issues/updates.

Might also be worth stripping the computer done piece by piece to see if its defective piece of hardware thats causing the issue.

Hello, everyone. I need some help I got brand-new va-10 mothervoard just yesterday, connected it and everything. While booting "CMOS checksum error - Defaults loaded" and "Press F1 to continue, DEL to enter SETUP" messages appeared on the screen. I chose DEL and corrected some of the set ups, BUT forgot to save the changes. On the next boot the same "CMOS checksum error..." message appears and computer freezes - keyboard does not work, pressing "del" or "f1" has no effect. I flashed the Bios sever times, but that didnot help. Any suggestions?

PS

I have a ps2 keyboard.

A:CMOS Error with Athlon 64 3200+?

POST Code / beep code

Per computerhope dot com slash beep dot htm

"POST ABCs - The computer POST (Power On Self Test) tests the computer, insuring that it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST the computer will have a single beep (with some computer BIOS manufacturers it may beep twice) as the computer starts and the computer will continue to start normally. However, if the computer fails the POST, the computer will either not beep at all or will generate a beep code, which tells the user the source of the problem."

From your description, the single beep meant that it POSTed okay...
but I am not sure what you mean by intermittent...

The codes will vary somewhat per bios... see the above website for more details.
It provides very detailed information on the post codes.

I have a problem.

I just bought a brand new kv7-v motherboard and AMD Sempron 2600+ from tigerdirect.

I went home, mounted the board properly, plugged everything correctly (I think/hope).

When I start it up, it seems to start fine with the default settings...but it gives me the CMOS Checksum error and I have to push F1 to continue.

When I go into the BIO and change it from the defaults to user define with the EXACT same frequency, my computer shuts off and sounds an alarm.

I have tried changing the power supply but I still get the same problem....

Can anyone help me?

First turn off the power

Remove the battery let it sit

Replace the battery after about 30 seconds

If you still get this error replace the battery itself

The CMOS battery may have worn out and needs replacing. It's a little silver, coin-shaped battery which clips on to the motherboard. Be sure to discharge electro-static charge from your body before touching the motherboard components.

Good morning to everyone. Why am I see CMOS settings error, press DEL to enter setup, press F1 to continue during boot up on everyday? Besides that, the CPU making loud sound during boot up and also when I am using my computer on everyday, I am not sure whether the fans or the HDD is the culprit.

Go into BIOS (DEL) and load defaults (either first screen or exit menu). Open the case and stop the fans with your finger for a second or two and see if the sound cuts.

A:Cmos Bad Check Sum Error On First Boot

Your CMOS battery is dead That's all.

Pop it out and go down to a hardware store or a radio shack and get a replacement. It's about the size of a quarter and is usually located near the bottom right of the motherboard.

A:Solved: cmos cheksum error

Hi and welcome!

I am going to assume that &#8220;when you turn your computer on&#8221; after turning it off completely, that you are receiving the error message &#8211; CMOS Checksum Error or Mismatch.

This is usually a result of the battery on the motherboard being defective or simply just being old. Which also leads me to believe you have an older system, the batteries usually last at least 5 years.

When this happens, your CMOS (BIOS) is reset to defaults, including the date and time of the system. You will have to enter the BIOS each time and at the very least reset the date & time on the system to your current date & time. If you do not do this, your operating system will have a hard time running or updating.

The batteries are usually simple to replace and they are also fairly cheap to purchase, around about $3.00 or so.

Thanks and have a wonderful new year!

Whenever my computer restarts it generates a checksum error and I have to reconfigure the CMOS. I have dual monitors, one crt and one tft. My system will not start without resetting the cmos unless i detach the tft monitor. I am running Windows XP pro service pack 2, with a ATI Rage 9800 pro graphics card. No changes to the system, Just suddenly started to happen. I can attack the monitor once XP begins to boot up, but not at restart.

How can the monitor affect the CMOS. If I start up with just the crt atached, boot up windows and then shutdown again, everything works fine. It is only if the tft is atached that I have problems.

Any one know what is going on?

I have an Epox mobo 4GEA+.

I am getting an CMOS checksum error - defaults loaded error.

I think I know how it happened - my little angel turned off the PC without shutting down XP.

When I turn on the PC I get a single beep and then the error. I cannot press F1, or any key, it doesn't seem to recognize the keyboard. I am locked up at the error screen.

I doubt its the CMOS battery because of the suddeness of the error.

Will clearing the CMOS activate the keyboard? Better solutions?
