My computer lost power while uploading an update now when i switch on i just get a blank screen


What was the update? Try a cold start, unplug, remove battery, leave battery out during this process, plug in, push on/off button, start normally. If that fails do a system restore/recovery. OR start in safe mode with networking to complete the update process.

Things You Must Know To Avoid PC Crash Part 3


7 Printers
The action of sending a document to print creates a bigger file, often called a postscript file.
Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer's performance.
If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default settings and you may be able to carry on.
8 Software
A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system properly. This will also remove references to the programme in the System Registry and leaves the way clear for a completely fresh copy.
The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.
Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org
Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the message "Starting Windows" press F4. This should take you into Safe Mode.
Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.
Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages (Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to disable the Level 2 (L2) cache if that doesn't work.
Remember to restore all the BIOS settings back to their former settings following installation.
9 Overheating
Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.
One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heatsinks are available from www.computernerd.com or www.coolit.com
CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more slowly, but it should also be more stable.
10 Power supply problems
With all the new construction going on around the country the steady supply of electricity has become disrupted. A power surge or spike can crash a computer as easily as a power cut.
If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.

Try a "Cold-Start",Remove all media, DVD, CD, USB..etc., Remove AC plug, Remove Battery, Hold down on/off button for 10 seconds, Replace battery, Plug into AC outlet,Push on/off button and Start normally.
IF THAT FAILS, try F-8 during pre boot, try to get to safe mode, or F12 to enter restore /recovery. After each try cold start, remove battery during this process.

My compaq presario CQ61 crashed. Have tried recovery but everything has failed. I have got as far as installing window files but it now is asking for the installation disc - I have not got one


You tried recover and it failed, and now you are trying to reinstall windows but you don't have system disc. Hmmm, have you tried rebooting and going into safe mode. Just curious, but you've probably wiped out your operating system by now doing the two things that failed.

You're going to need an operating system disc to get you out of this.

Ipod says charged, but when i unplug it it cuts


  1. First thing to do is restore it to factory settings to see if that corrects the problem.
  2. Make sure you’ve installed the latest version of iTunes.
  3. Open iTunes, and then connect your iPod to your computer.
  4. After a few moments, it will appear in the Source pane in iTunes.
  5. Select your iPod in the Source pane and you will see information about it appear in the Summary tab of the main iTunes window.
  6. Click the Restore button. A window will appear asking "Are you sure you want to restore the iPod "iPod" to its factory settings? All of your songs and other data will be erased."
  7. Click Restore again. (If you're on a Mac, you'll then need to type in your password.)
  8. During stage 1 of the restore, a progress bar will appear on the computer screen indicating that the first stage of the restore process has started. When this stage is completed, iTunes will instruct you to leave iPod connected to your computer to complete restore.
  9. During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage. Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.
  10. After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.
If all else fails and the battery is bad, replace the battery. Here is a video that will show you just how easy it is. No need to pay Apple any more money than you already did to repair it.
