• My computer has stopped recognizing my DVD burner.

  My computer has stopped recognizing my DVD burner. It will still read and write to a CD. I don't remember adding something new to the computer, but am not sure when it stopped to work with precision. The Device Manager shows his work; I tried updating the driver but it says that it is the most up to date; I uninstalled and reinstalled; I checked regedit and there are no filters; It is recognized in the BIOS. The store said it is not the hardware and you want to reformat the computer. What can I try before taking this step? Thank you.

  Hello Allisonjak,

  Thank you for your message.  You said try to update the drivers.  You go to the computer manufacturer's website and download/install the latest driver for your computer?  If this isn't the case, it is the recommended method for updating your drivers.

• My computer has problems detecting the USB cords.

  As applications for title, my computer can detect things that I rarely connect into it. When I got to my new iPod touch 3 years ago, my computer it confused for a Kodak camera. I don't remember how I managed to finally recognize my iPod, but it does also with other things that I try to use. As my friend for example hard drive, it works perfectly well on his computer, but when hook us up on mine, my computer gives power to the light, but will not be displayed on my desktop. My keyboard also uses a USB cable, which only works in the USB slots at the front, because in the rear slots, my keyboard only works for about a week before he refuses to work for me and then I have to pass to the slot machines. Is there something wrong with my connection I can fix it?

  Try to buy a USB hub powered (one that plugs into your computer for its USB connection and which has also the power to the USB ports to plug into the extra wall) and see if that helps.  Some computers provide the power to the USB ports and this can cause problems with the devices.

• My HP pavilion DV7 1245 x with Vista has stopped recognizing the CD.

  When I put a DVD/CD player and click on the disc or the player open, it is said, please insert the disc in the drive.  When I put a CD inside whirs for a little while but when I put a DVD in nothing happens at all.  When I ran FixIt it says fair-media is not readable, but I tried all kinds of DVD and none of them work.

  You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
  Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
  correctly.

  A CD/DVD cleaner might help.

  Brand of the CD or DVD drive can also be the problem. Low quality (cheap brands) are always problematic.

  CD/DVDs have a tolerance + - and your can read/write on the edge outside these discs
  tolerances. They may be delivered, but it is generally more economical to replace the disk.

  Step 1: Please do all the same underneath if you did some before as is often total
  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and

• My Lexmark printer stopped working and the error message says "printer cannot communicate with the computer" (from "twisted into the USB pins?).

  When my printer stopped working because of error messages about "printer cannot communicate with the computer" (from "twisted into the USB pins?), I tried to change to 2nd USB port without success. I tried a new cable; that did not help.

  Then I uninstalled and reinstalled my Lexmark printer and changed the error message. Now, the printer does not work because "the USB device is not recognized."

  I tried to update the chips; Use 1 USB port; and using the old cable, all this without success. I checked the connections of the cable to the printer and the PC and turn on the printer and goes off; I'm out of ideas. Any other suggestions?

  Original title: Windows Update does not work on security with networking mode

  Hi, if my computer has been doing the BlueScreen thing where it stops every 5 minutes when I go to normal mode. So I go on security with networking mode and I went to problem and solutions and all this stuff, and the Web site that came to help me solve the blue screen was told to go to "All programs" and then go into "Windows Update". but the problem with that is does not work! My cursor will give me the circle of loading bit for a few seconds and that's it! And don't tell me to go to because every time startup repair I have try that he asks me "User" and I tried everything and nothing will work! :/ And apparently, it's a driver problem, not a hardware problem, because I already removed and put in the back of my equipment. Then Yes.

• Equium A60-155 has stopped charging the battery

  Hey all
  Can anyone help?

  For no apparent reason my A60 has stopped charging the battery, it works very well with the cord in but take out and matrices of the computer. Energy saving says that it does not load but defaults to full power with the power cord in. I tried to remove the battery for a while and change the power settings, but nothing helped. This happened to someone else? I have to buy a new battery?

  Thanks in advance

  Hello

  To me, this looks like a charging problem and it can be caused by power supply to electronic malfunction. Perhaps only the battery is dead. However the best solution is to contact the Toshiba service partner because he can start the diagnostic test and then give you an appropriate response.

• My computer has stopped downloading of updates due to an era 8007000 b. What does that mean?

  MY computer has stopped downloading of updates due to an era 8007000 b. What does that mean? Donald strickland

  Hello donaldstrickland,

  Thank you for using Microsoft answers Forums.

  Solution:

  Windows Update, Error 8007000 b

  If you receive the 8007000 b error when you try to install updates for Windows 7, the Windows file system transaction log is damaged. The transaction log is used by the Windows file system to recover when a file error occurs. To correct this error of update, you clear the log. Here's how:

  To clear the file system transaction log

  1. click on the Start button and in the search box, type command prompt.

  2. in the list of results, right-click Guest, and then click Run as administrator.  If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

  3. at the command prompt, type the following command and press ENTER. (This command assumes that drive C is the drive where Windows 7 is installed. If Windows is installed on another drive, change the drive accordingly letter.)

  true fsutil resource setautoreset C:\

  4. you should see a message saying that the operation was completed successfully. If this is not the case, check your spelling and try again.

  5 Type Exit and press ENTER to close the administrator: command prompt.

  6. restart your computer.

  7. download and install the update again.

   

  That should solve the problem.
  

  
  Thank you.

• Vista has stopped turning the games run for a long time.

  Vista has stopped turning the games run for a long time. The display would go crazy and the sytem would lock. Gotta make a stop with the power button. No errors are recorded. I re-installed the game. Same thing. I reinstalled Vista 64. Same thing. I get about 3 minutes in the game and then locking the. 1 single game still work (BioShock2). COD - MW2 and COD MW lock the sytem. One is direct install, and the other is the steam. I have a video card Nvidia GTX 280 with the latest drivers from Microsoft. Before the reinstall, I tried to install the most recent NVIDIA. Did not help. Yet the locks without showing error. About half of the time it stops at my off video card a few seconds after that the display goes crazy. BioShock uses DirectX 10, and others use DirectX 11. I read on some sites that 11 causes the video crashes on some systems. I want to know is why 11 is working for so long and stop NOW. Is there a way to make the games all run on 10? COD BlackOPS crashes too. I played ALL these games over and over again until the last 3 weeks. If there was some error to post logs I would but there is not. Any suggestions on where to find some kind of problem that could cause this? The video card was removed, cleaned and put back into the computer. Still crashes. 1 in 4 of the games will take place without any problems. 3 will be blocking of the computer and the video trash in 3 minutes or less to start the game. The video is great, until blocking.

  Suggestions on how to fix or where to additional troubleshooting for the cause will be greatly appreciated.
