Computer specs:

Windows XP 64bit
ATI Radeon HD 4870
Acer x213W monitor


Hello,

Sometimes, in some games mainly, my screen flashes white/black. If the game is windowed, then only the window flashes.
I doubt it's the monitor because I have two monitors and the same thing happens when I move the flashing window to the other monitor.

It doesn't ALWAYS flash but it flickers now and then and it gets annoying.

Any idea?

I see no other option, but maybe your video card going bad.
Are those games pretty resource hungry?
Did you check video card temperatures?
When was the last time, you cleaned the computer inside, including video card fan?

Try adjusting the refresh rate.

Control Panel > Display > Settings Tab > Advanced > Adapter

1. It's brand new.
2. Nope.
3. How do I do that?
4. Never.. but it's pretty much a new computer. (A few months old actually.)

That's what I get when I go there:

1. It's brand new.

It doesn't guarantee anything.

Download, and install SpeedFan: http://www.almico.com/sfdownload.php

Provide processor info (hold Windows key, and hit Pause/Break key to find out).

Click List All Modes on that Adapter tab and try lowering it, or try increasing it.

Temps look fine.
Did you try to reseat video card?
If this is a card, you installed yourself, I'd also try to remove it completely, enable on-board video, and see, if same thing happens.
