windows 7 - Some Portions of Computer Running Slow (Specifically Graphics)

I noticed that a few things are running slow today on my Windows 7 laptop. Specifically, they are:

• Opening and closing windows takes several seconds for the animation to complete.


• Windows media player opens fine, but the movies are very laggy


• MMORPGs are extremely laggy


• When waking my computer from sleep mode, after entering my password, my desktop takes about 3 seconds to fade in

Other than those, everything runs at a normal speed.

Things I've done that maybe contributed to this problem:

• Changed the graphics processor (by plugging in/unplugging the charger) [however, no matter how I change the graphics, I'm still getting this lagginess]


• Installed AdBlock, a Firefox addon [I recently removed it, and I'm still experiencing this problem]


• Went into Advanced System Settings, Clicked Settings, and unchecked a few visual things (such as the animation for opening and closing windows) [sure, this got rid of the opening/closing windows lag, but I like that little animation - plus that leaves all the other lag problems I'm experiencing]

So, does anyone have any ideas/fixes? If so, please respond. Thank you.

Some Other Information:

• I'm on a HP Pavillion dv7 laptop, 4285 Entertainment PC, with: intel CORE i5 inside, ATI Mobility Radeon Premium Graphics, Microsoft DirectX11


• Opening and closing of windows: Defined as opening a program (i.e. Firefox) or closing it by hitting the X in the upper-right hand corner. Lately, the animation for opening and closing windows (which is simply either growing from the icon from the taskbar to fill the screen, or shrinking from the screen down towards the icon on the toolbar.) This problem also occurs for minimizing/maximizing windows.


• Very laggy movies: defined as .avi movie files saved to My Documents which skips several frames per second and seemingly slows down the movie as a whole


• Extremely laggy games: I tried playing an MMORPG today, and movement in the game was at least 10x slower than it ever has been, even when playing on the lowest detail/graphics


• Desktop taking 3 seconds to fade in after sleep: in this scenario, I had no other programs running visibly. The computer generally fades to black from the password screen to the desktop in about 1 second, normally. However, it is now taking 3 or more seconds.

Answer

I received this answer on a different forum, and now my laptop is running perfectly again

OK, before doing anything, I suggest updating your Windows. Go to Control Panel > System and Security > Windows Updates > install everything you can and restart your PC.

Also, update your Graphics Drivers (when you don't have a video driver, everything works a little slow, you can check it out by opening the browser you are using and slide it over your desktop from left to right. If it slides in frames then probably is your video driver). To update your graphics go to Start > type Run > type in Run DxDiag > and search for your video card manufacturer on the Display tab > go to Google and search for your manufacturer (I.E: ATI/Nvidia drivers).

Go to their official website and get the latest drivers available for your Graphics Card > install it > restart your PC.

Also, update your DirectX, link bellow:
