Y550 -- Strange dots appear on screen when running in "True Color" mode.

 First here are some important details, we're dealing with a Lenovo Y550, Windows 7, Intel dual core 2.2 ghz, and a Geforce G210M graphics card.  

 

The problem is that the screen shows a bunch of white or lighter colored pixels in a grid like pattern after opening and closing applications in "true color".  It started yesterday afternoon and the only thing that changed at that point was that some Windows updates were installed.  Thinking that the updates messed with something, I did a system restore to a previous date--no help.  Then I updated the Nvidia graphics card drivers--no help.  Uninstalled the updates--no help.  Reverted back to the original graphics card drivers--no help.

 

Further troubleshooting says it may be the graphics card as it's only really bad when using the "true color" setting.  When I drop it down to "high color", everything looks fine until graphics acceleration is required--like when opening the nvidia control panel, selecting "adjust image settings with preview" and the spinning nvidia logo starts to flash a bunch of random white pixels.

 

Any help would be appreciated...

hope it's not dead pixel issue.

a screen preview'd be nice if possible.

No, it's not a dead pixel issue and I wasn't able to figure out how to upload a screen cap.  If you could let me know how, that would be cool.

use printscreen "prtscr" button ( on the right side of f12 ) press once, then open ms paint

( pressing windows + r, type "mspaint" and enter ) then press ctrl + v to paste it. save the file on your desktop,

hit imageshack, read faq for how to upload or browse to select file from your desktop and click upload. paste the link here.

This one is of the desktop at true color...

This one is of the desktop at high color, but you can see the dots in the nvidia animation

The dots move around based on what I'm doing and watching youtube or hulu is practically out of the equation.

did you just re-install nvidia drivers or un-install it, restart your computer and install it?

First, I installed the updated drivers from the nvidia site and rebooted.  Then I uninstalled the drivers, rebooted, and then installed the drivers that came with the system.

can you try to update your graphic driver from nvidia? ( 32 bit windows 7 - 64 bit windows 7 )

and please remember to get latest direct x, too.

( i'm just trying to fix it, if you make clean installation for your system, i'm sure it'll solve the issue )
