    i had a black dos screen come up with the usual safe mode options or start normally

    after that it loads only it appears to be running slower (memory?)

    the flickering occurs more frequently now but after the cpus been on a while (could it be the connections?)

    If the screen is flickering a lot, it could be the backlight--does it have a manual brightness switch (like a slider switch)?
    It also could be the video card, but I'm inclined to think it's the flourescent backlight.
    You say it turned off by itself? Did the monitor just go black or did the computer actually shut down?

    Yes, it could be the connection to the LCD, but one thing I would try is to blow the dirt out of all the spaces in the computer that might affect cooling.
    Have you tried, also, to run disk checking for errors (scandisk)?
    Another question (maybe silly, but...) are you running a good anti-virus product? Have you been scanning for viruses. You might want to try one of the online scanners just in case. You can use Trend ( or Panda (

NP--Whenever I find that type of problem, I first suspect malware, then power or heat, and then maybe programs that just shouldn't be running.

Try running MSCONFIG. Shut down programs or utilities that you don't recognize.

Flashing dome light, broken horn, and slow windshield wipers... what can it be?

if your hearing a clicking sound when pushing the horn button then it sounds like you need to replace the horn the diaphram is probably no good.if it was a bad connection you wouldn`t hear a clicking noise.the slow wipers sounds like it could be a poor ground on the wiper can run a separate ground wire to the wiper body and if the wipers work at a normal speed then that is all you have to do.if not then the power wire needs to be checked for battery voltage if its good then the problem is likely the wiper motor itself.the flickering interior light may be the light switch maybe moving just enough to make contact to allow power to the light.make sure the switch is into the off position and see what happens.

Can you check the function buttons and make sure the primary display is set to show the output on the laptop. Try repairing your OS. If not then re-install the os. As you are saying till the time windows gets loaded, all works fine so it seems the issue isn't really the hardware.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out

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.

Panasonic PS/NS-GS200 - Some enquiries!

1. try changing your screen refresh rate. 2. yes, it is called EIS. you can switch it on from the menus. The EIS does not work well in low light. a tripod is your best bet for a steady camera. 3. the backlight feature back lights the LCD screen only. to shoot in low light switch the camera mode to manual and change the menu setting to low light. the magic pix mode will help you shoot in the dark but any movement will become blurred. Again, best to use a tripod in this situation. Detailed information for items two and three should be in your manual.
