Question about Computers & Internet
My computer started going into a blank screen at random times. There is no response on any keys. Only way is to turn off computer and then back on. It does this at random and seems to be increasing in frequency. Any suggestions?

If this laptop is only a few monthe old, then it should be still under warranty. I suggest you return it to the supplier for repair or replacement under warranty. If you try to repair it, most likely you wil void your warranty.
If you don't have this choice then read the following info.
You most likely have a faulty CCFL lamp or inverter, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the 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.

not to get to concerned just yet, a few tips, when you press on the top of the laptop case by the screen area in the back of the laptop do you notice the screen flickering off? and when you let go dose it come back on? if so this can be a faulty wire or bad inverter, they are actually both very simple to fix and relatively cheap fixes.
