  can anyone tell if this can be fixed if it can and you know I would appreciate it a lot

  Oh and I got a windows vista disc to see if it downloads it, but just on the same screen

  The "boot block" needs to load the rest of the BIOS of a memory chip. Since it doesn't, either the battery on the motherboard (a piece the size of a $0.25 coin silver) has failed, either the content of the memory chip cannot be read.

  Replacing the battery is fairly easy.
  First of all, notice the writing on the top of the battery.
  You will need to put the new battery into the socket,
  with similar writing facing face up into the socket.
  Look on the edge of this battery to a small 'finger' which holds the battery in its socket. Push this "finger" of the Center, and the battery must be able to be raised.
  Remove the accumulator at any computer store and get a replacement.
  Insert it, and then try again.

  If the problem persists, then either he must:
  * Replace the motherboard
  * replace this chip memory (which can be soldered on the motherboard at all times).
  * replace the computer, taking the disc drive of the old computer and its connection as a 'slave' the drive in the new computer.
  * take your computer to an expert technician.

  The attempt to boot from the CDROM is a process "emergency", to use when you have a specially created CD disc that contains a copy of the software to load into the memory of the BIOS chip. It is not a 'normal' start (to load the Vista disc).

• Desktop M8000 giving Bios Rom Checksum Error

  Hello

  My brother-in-law gave me their old tower to see if I could not going again for their children to use, the decent machine actually, he had 2 internal hard drives in it and he said it was more than ever and lock up often.

  The pc don't was not start (sitting at an empty screen) even if it had worked before, so the first thing I did was to remove the two hard drives and their hung outside for my main pc, he said, I wanted to see if they were healthy and if they had the virus on them, etc.

  Health check, past, defragmented both drives them (OMG they were horrible) and on the storage disk ran a virus scan and spyware scan (zero problems) spybot seek and destroy and completely updated avast updated etc.

  On the main C drive, I did Defrag, ran the spybot captured about 10 things mostly of cookies, nothing horrible, then ran avast, it is 17 things in temporary files, remove hit at the end of the scan, re ran the scans and it came out clean.

  Then the two drives are checked as work/healthy, defragmented, virus and spyware cleaning, put it back in the system and I still get the screen white, but maybe 1 out of 10 times I get

  Hello FTLOSM, reads that you list are fairly normal. A difference of one or two points on the readings should not be a problem, especially if the power supply is connected and powered. The 12 volt rails are mainly used for engines on the disks, so a small difference in the actual 12 volts would be well within tolerances. If 3.3 volts reading falls below 3 volts, then I'd be concerned.

  I would tend to think that the motherboard is the culprit, since it is rare that a processor will fail under normal circumstances.

  It usually takes a voltage spike to get a processor.

• Aurora R4 BIOS ROM Checksum failure but boots 50% of the time?

• Desktop Pavilion a6305: bios rom checksum

  When I turn on my computer, it is said, bios rom check sum. I know nothing about computers and I would like advice please thanks

  Assuming that came and he didn't juggle the PC before that, then the BIOS has been damaged, or there is another hardware problem.  I would first try to replace the CMOS battery, then if it does not, it might be time to consider replacing the motherboard or the whole PC.  The technical page so that the PC says that it is the end of 2007, which, if the CMOS battery has never changed, then this pourrait be the problem.

• HP model #A6000n Bios Checksum error after update Bios!

  I did update the Bios posted on the Hp website... After the reboot, all I get is this error, "BIOS Checksum Error", the black screen then looks for a boot diskette drive (this computer has not), then it looks for a boot on the CD drive disc.  Now, I talked to HP support and they say I have to order the recovery disks.  Someone can send me a bootable file that I could burn it to a CD for this model machine and get it operational?  I have an older machine here that would allow me to make a bootable CD, but I have no idea where to find some sort of update of the BIOS and or file bootable to Flash the BIOS.  I am so angry that HP wanted me to buy this CD recovery program has just returned in Windows Vista.  But, I don't know what to do because the update of the BIOS must have been corrupted when I flashed the motherboard ASUS.  This computer is my aunts and she failed to save restore disks and now I'm lost as to lift this thing up and running... Help, please!

  Thank you!

  As I said, if you have a floppy is easy, especially since the computer diskette is XP. OK, let's go.

  (1) place the disk in the drive

  (2) open my computer and right-click on the floppy drive

  (3) choose the format on the menu that appears

  (4) put a check mark in the box "create an MS-DOS startup disk".

  5) click on 'start '.

  When 6) filled the awdflash.exe on the diskette copy

  (7) right click on the file of BIOS from HP

  (8) to move the mouse cursor in 7 - zip and click "open archives".

  (9) double click on the folder icon in the new window

  (10) right click on the ROM file - in this case 513. ROM

  (11) choose "copy to" from the menu and browse it on the floppy

  (12) when it is completed, the disk should be ready to work

  (13) move the floppy drive cable and the Ribbon in the Vista computer.  He didn't need to be mounted, but make sure that it does not touch something metal (participation of books will be good) and connect the water and the power supply to the motherboard and the power of the Vista computer (of course, it is done with both computers turned off and unplugged)

  Now ready to go on the Vista computer. When you press the power button on the computer, there will be a splash of HP come screen upward.  From this screen, press her "enter the BIOS' or 'Boot to install' as shown.  I forgot to ask if this screen appears in the previous posts.  If this screen does not appear then it will be much more difficult.

  When in the BIOS, look for boot order and then set it can boot from the floppy first.  Save the selection to get out.

  (14) reboot - should end up with a cursor blinking in the upper right

  (15) type AWDFLASH 513 rom/py/sn/cc , and then press ENTER.

  (16) when and if he finished power down and remove the drive from the computer disk

  That should do it.  If this does not work or there are problems come back with an explanation of what was happening.

  Of course, to do this at your own risk.  I'm just trying to help.

  Hello

  This message always appears during the clean boot procedure or it appeared only once?

  Generally 'bad checksum' error message if the CMOS battery does not work correctly.

• Help on Checksum error, BIOS freezes... Windows XP

  I have a desktop IBM 621932u.  Master 40g HD, 320g slave.  Operating system is Windows XP Professional.  He was not connected to the Internet since the 07.  I mainly use it for music production.

  I tried to connect a SONY HD TV to the video card.  Of course I had to change the screen resolution sizes.  Shortly after changing screen resolutions that would flicker the entire map video, then black.  I thought that it could not handle the HD TV.  I'm stopping with the power button because I couldn't see the screen click 'stop '. I reconnected my regular monitor to the video card and rebooted, reach out to the office.  To try to change the resolution of the screen to its original state, all of the computer froze and the screen went white.

  Upon restart, the computer would not let me go beyond the Professional Windows XP splash screen before the screen would go black and it would freeze.  I reached 44 attempts to restart failed (the cpu was told that).  It got to the point where I couldn't do it at the startup screen and it would freeze just after the BIOS splash screen.  I changed my BIOS back to default settings.  Nothing changed even after that.

  I checked my memory.  There are two sticks of memory.  Try to restart with a stick, then two, then alternating them and then finally let them all together (of course, this did not worked but what the heck right?)

  I had a hard drive of 40g with Windows XP installed.  He also wouldn't let me go beyond the XP splash screen!

  Then I had a checksum error, and the cpu does not load beyond BIOS.  I changed the battery, but it still freezes.  Occasionally, he would give me access to the XP splash screen, but it will freeze once a single bar flies through the screen.

  Once again, a mosaic of colors appeared on my screen to enter the BIOS.

  Sounds like you damaged your video card. Take it out and install a well-known work. If this is the problem, take the original video card. MS - MVP - Elephant Boy computers - don't panic!

• HP divided x 2: BIOS Checksum Error (502) HP Split x 2

  A couple of days, I turned on my laptop (product number: G6Q88UA-#ABA) to see a black screen with white text saying he had a (502) BIOS Checksum error and press ENTER to reset the values and continue with my system startup. Once, I have to update to the current time. As the days passed, I noticed that I was unable to turn on my laptop without plugging it into the wall, and disconnect it would cause my computer turn off and therefore lost all of my work (and time settings). My poking around led me to him or the other being the CMOS battery, or a corrupted BIOS. I believe that my BIOS is up to date, and my model does not appear to be a CMOS battery.  Can anyone help? Thanks in advance.

  ehill612,
  Thank you for visiting the Microsoft Answers community forum.

  Has anything changed summer on your system recently as new hardware or software installed any new updates?

  What kind of computer you have - laptop or desktop computer and what brand and model?
  This information will help us to help you solve this problem.

  Start by checking the file system corrupted system and check the hard disk for errors.

  To run the System File Checker tool, follow these steps:
  Click Start and type cmd in the box start the search.
  Right click on cmd in the list programs, and then click Run as administrator.
  If you are prompted for an administrator password or a confirmation, type your password or click on continue
  At the command prompt, type the following line and press ENTER:
  sfc/scannow
  When the analysis is complete, test to see if the problem you are experiencing is resolved.

  You can help solve some computer problems and improve the performance of your computer by making sure that your hard disk has no errors.
   
  1. open the computer by clicking the Start button, click computer.
   
  2. right click on the hard drive you want to check, and then click Properties.
   
  3. click on the Tools tab and then, under check for errors, click check now.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  To automatically repair problems with files and folders that the scan detects, select automatically fix file system errors. Otherwise, the disk check will simply report a problem, but not to fix them.

  To perform a full disk check, select search and attempt to recover bad sectors. This scan is trying to find and repair physical errors on the hard drive itself, and it may take much longer to complete.

  To check for errors file and the physical errors, select both automatically fix errors in file system and search for and attempt recovery of bad sectors.
   
  4. click on start.
   
  Depending on the size of your hard disk, this may take several minutes. For best results, do not use your computer for any other tasks while it checks errors.

  Note: If you select automatically errors in file system of fix for a disc that is used (for example, the partition that contains Windows), you will need to reschedule the disk check for the next time you restart your computer.

  Send us information about your system and the results of these tests.
  Thank you
