Sometimes in the middle of any process my screen just went crazy, the contents flickers - they scroll over and over the screen. The only way to solve it is to reboot it. A friend indicated that the resolution might be the issue. However, after I reduced the resolution it still happens, just less frequently.

Re: The screen flickers, have to reboot it
Start by checking Dell's support site for updated video drivers, then uninstall the drivers for the screen from the device manager, then reboot. It will find and reinstall them. If this doesn't cure it, then this is going to be a hardware issue. Start by checking the screen connections, they sometimes work loose. If the connections are good and the problem persists, it's going to be the inverter or screen, and unfortunately, replacement is your only option.

This is a common HP fault it's caused by the chip just about the touchpad. Unfortuately there is no great fix for this, infact it will get worse before it gets better. I have similar problems with a customers laptop (HP NX6110), I took the motherboard out and refolwed the solder on the chip but this only fixed the problem for a couple of weeks and then it went back to doing the same thing again. Try to find a computer engineer to perform that and see how long you can get out of it. Sorry there is no quick fix.
You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp. To determine if the video card or the LCD is faulty, 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. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Hello... I had the same problem before (actually, twice) and it was the LCD - 'twas broken. So I returned it to the company and they replaced it (twice). Thanks that it was still covered by its warranty, I didn't pay even a single cent. You really can't use it well if the screen flickers but if you can not return it right now (hope it's covered by warranty), you just adjust the light of the screen by pressing FN and F9 (for light). That way, you can use it but expect that it will turn white afterwards and so you can't see the cursor again. It's only your broken LCD that needs to be replaced. Hope this helps... If you've got more questions, just feel free to ask more questions here, thanks! tc :)
I am sure that the issue is related to the cable that connects to the LCD Display or the LCD Backlight.
There should be some connection shortage because of which the LCD flickers few times as stated by dan231.
I Recommend you to get the Notebook examined as soon as possible before something really goes wrong...
Access BIOS and test if the flickering continues.
If not, it is a Software problem, do a full system recovery If yes, it is a hardware issue, better contact Toshiba tech support to have your LCD repaired if you are still in warranty.
If your not in warranty, you need to check out the LCD harness that might have been loosely connected.
