How familiar does the following sound? Your computer was working fine, but then suddenly started locking up (aka hanging or freezing), rebooting itself (crashing) or shutting down spontaneously? If you know only too well what I am talking about, then read on! Performing the simple steps below can fix the majority of lockup cases.
1. Check for recently installed software or hardware.
If the lockups started to happen after you installed a new peace of hardware, new software program, or new drivers, uninstall it and see if the problem goes away.
2. Run your antivirus program.
One of the first things to do in the case of sudden lockups is to run your antivirus program. Check your antivirus manufacturer's website for updates and latest virus definition files. (This is absolutely necessary, outdated antivirus is not going to be of any use!) If you don't have antivirus software installed - or if updates are unavailable - run one of the web-based antivirus scans that some major antivirus vendors like Trend Micro are offering for free. You can find a comprehensive list of available web-based scans and free antivirus programs on http://www.free-antivirus.info.
3. Run some good spyware removal tool.
If your machine is not infected with any viruses, it is still possible that it has some harmful adware or spyware is present. Download and run some good spyware removal tool such as AdAware or Microsoft AntiSpyware. Check http://www.free-antivirus.info for a list of free spyware removal applications.
4. Check for free hard drive space.
When no viruses are found, check out free hard drive space on drive C:. Make sure there is more than 20% of free space available; low disk space can lead to random lockups.
5. Check for overheating.
Overheating is another known cause of lockups. It can be caused by problems with fans inside the case, dust buildup, or other cooling problems. Make sure the power supply fan and CPU fan are running and free of dust buildup. You can check the temperatures inside the case by running Motherboard monitor
http://mbm.livewiredev.com
- make sure the temperatures are within the preset limits. Be very careful while cleaning inside the computer case (use plastic vacuum crevice tool) and NEVER OPEN THE POWER SUPPLY CASE as it contains high voltage.
6. Check the hard disk.
Check the hard disk - it is possible that its logical structure is corrupted. To check the disk for errors, right-click on the disk C: icon in "My Computer", select the "Tools" tab, check all check boxes in the "Check disk options" field, and press the "Check now" button. It should ask whether you want to schedule the check next time you restart your computer - answer "Yes" and restart your PC. The check will be performed automatically after startup; it can take a while, so be patient. The program will attempt to fix some problems automatically - however, if the hard disk is failing physically, it will need to be replaced. It is also a good idea to run Disk Defragmenter (located in Start Menu > Programs > Accessories > System Tools) to optimize data placement on the hard disk for increased performance and reliability.
7. Check the memory.
Sometimes random lockups can be attributed to the computer memory (RAM) starting to fail. You can test the memory by running Windows Memory Diagnostic that can be downloaded from http://oca.microsoft.com/en/windiag.asp. If memory problems are found, try re-seating the RAM (pull it out and plug it back in). If it doesn't work, replace the defective RAM.
8. Check for other hardware problems (advanced users).
More hardware-related problems can be diagnosed by running hardware tests from the Ultimate Boot CD that can be downloaded from http://www.ultimatebootcd.com. However, you should only use it if you know what are you doing - some programs on that CD can be dangerous when used inappropriately (for example, some of them can wipe the contents of your hard disk).
9. Update Windows and drivers.
Some lockups can be caused by outdated software components - update your windows and drives by running a windows update: http://windowsupdate.microsoft.com (it's good idea to run it regularly).
The above steps will help diagnose and eliminate the most common causes of lockups. Hundreds more of other possible scenarios need to be dealt with on a case-by-case basis, as it all goes down to your particular computer configuration. Asking on PC
troubleshooting forums/newsgroups should help you figure out solutions to not-so-obvious lockup cases.
Any avid Apple fan seriously interested in typing on the iPad must consider other options to an iPad's built-in virtual keyboard. The Bluetooth enabled Apple Wireless Keyboard may be the ideal alternative to the iPad's virtual keyboard.
The Apple Wireless Keyboard uses the iPad's built-in Bluetooth functionality to deliver a simple and responsive typing experience for iPad end users without having to be tethered to your iPad with a dock. It is also a suitable replacement for the touch screen functions with the native keyboard shortcuts.
Setting up the Keyboard to partner with your iPad is very easy. Touch the Apple Wireless Keyboard's power button on the right side of the keyboard till you see the green indicator light turn on. Next, go into your iPad's Bluetooth settings to pair the Apple Wireless Keyboard. That's it!
Apple's Wireless Keyboard for the iPad and Mac computers takes up nearly a quarter less space than traditional keyboards, is incredibly thin, and has a featherweight light design. The Keyboard follows Apple's minimalist, yet fashionable styling. The keyboard is made of an aluminum casing, white plastic matte keys, and a plastic back panel. The aluminum casing allows for the sleek and slim look but is remarkably strong, suitable for any mobile road warrior or clumsy student. The top of the keyboard has a raised circular cylinder housing two AA batteries. This also has a pragmatic function that houses controls and user interfaces while also providing a pleasant and ergonomic typing angle. Typing for a few hours was comfortable and is comparable to typing on our 15? Macbook Pro. This Wireless Keyboard features scaled down QWERTY keys, a directional pad, and media control keys that allow skipping tracks on the iPad. In addition, the keyboard has function buttons which allow to change display brightness, sound volume, and a disconnect button that allows quick return to touch input. We consider this very much a value buy if you own other Apple computers. This keyboard can be used on your Macbook Pro or Mac desktop.
