Question about Computers & Internet
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing.
Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/ There is a connection problem such as a bad cable
Test all power and data leads that attach to your hard drive SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a secure dust free connections and are not faulty. Although it would be very rare for the sata lead to be faulty. Make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty Computers need power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error
Hope this helps.

SOURCE: my laptop screen is flickering
You most likely have a defective inverter that supplies high voltage to CCFL backlight. It is unlikely a faulty CCFL lamp because your laptop is approx 1yr. old.
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is the inverter or backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Try reseating the memory one stick at a time in each slot one at a time and see if you can get video that way. If you can't constantly get video after this then take out the hard drive and then the dvd drive,
If your still getting intermittent video then the motherboard might be bad. You can also try another stick of known good working memory to make sure the existing ones you have are good.
If your still getting intermittent video then the moterboard is bad and would need to be replaced.

Unseat and reseat the memory one stick at a time in each slot on at a time. After each reseat of the memory, turn on the laptop and see if you get video. If you still don't get video, go ahead and take out the hard drive and the dvd drive.
Then try turning on the laptop, if you still don't get video then the motherboard is bad and you'll need to get it replaced.
