My computer screen KEEPS flashing. Flashing starts soon after I start the computer and continues randomly until I shut down the computer.
Why could I do to get rid of flashing?

I have tried following things:

Made sure that cables are properly plugged.
Using other monitor.
Using other dvi cable.
Using other power cable.
Updating my graphics card's drivers.
Took my graphics card off and used integrated, same problem with it.
None of these helped.

My graphics card is GeForce GT 220 and my monitor is 22" tft. Windows 7 is OS.
What happens in safe mode?Could you try to describe the 'flashing' in a little more detail please? Does it flash with a bright color or does it go dark? how frequently does it happen (is it at a consistant interval or does it appear random)? Does it make a sound when it's flashing (like a popping sound)? Is there a sound from your computer when it flashes (fans hesitating or speeding up momentarily etc.)? Does it actually effect the on-screen ACTIVITY (mouse pointer pausing etc.)?

Sorry for all the questions but you have already covered pretty much every thing I would have tried, so some more information may be able to help in the search for a solution.

Thanks &
Good LuckHopefully its not a motherboard that's broken. Oh, and one other thing...has it always done this, or has it only started recently?

Have you tried plugging the monitor into a totally different wall power-outlet. Kinda grasping at straws here, but maybe there is a fault with the power outlet.In safe mode there is no flashing.

Flashing is sort of white, no other colours. It's QUITE random, not constant. No sounds. It doesn't affect mouse movement or such.

The problem started soon after I moved my computer to other room. Before that there was no problem.

I'll try using other power outlet next.Never mind the power outlet. If it doesn't happen in safe mode the problem is caused by some software that is loading - possibly the driver. Download and install the current driver for your video card and let's see what happens (get the driver from the OEM web site, not from Microsoft UPDATE).EDIT---Just noticed you mention Win 7 in your first post... Try disabling the Aero features and see if it still occurs.

Are you using XP as stated in your profile? I have heard of Aero theme causing similar issues, but that would only apply if you have upgraded to Vista or win7....Profile details are from my old computer, this new one runs 7.

I'll try disabling Aero and reinstalling drivers next.

EDIT: I tried both, but it didn't help.How did you move the profiles ? ? Quote from: patio on July 07, 2010, 01:27:22 PM

...I looked closer at my motherboard and noticed that one capacitor has blown up.
Is that probably reason for my problems?

Hopefully its not a motherboard that's broken.

And the best thing right now is to take your CPU to a computer shop who have available services for repair so that they can have a thorough check on your motherboard and system. And also, check your monitor that comes with your broken CPU to other working CPU unit just to pinpoint that there is no other issue aside from your CPU unit.
