Video Card problem?
 

I've been noticing some problems these days when I'm playing a game and hit the window button or alt tab and I have a Nvidia geforce fx 5200 video card. Like if I press the window button while in a game or alt tab I get this tv static looking thing except it's colored lines kinda as it goes to the desktop. Like for example I'm playing World of Warcraft these days and the settings are all on default and I've never had a problem before but now if I press the window button or alt tab, it takes much longer now to go to my desktop, it's like the game freezes or some thing for a few seconds. I'm guessing it's my video card but I'm not 100% sure, and I did download the drivers for it.

No way around it. Your system colour depth and resolution is probably different from the one used in the game. Try not to trigger the Winkey, or ALT+TAB while in-game.

Playing in a windowed mode might help, but personally I say it's your interest in playing World of Warcraft. Your resolution won't really change in the windowed mode.

Yea but the thing is it never happened before and now it is, I can understand if it never happened before but why now?
