Windows 7: Random pixel boxes showing up on desktop

Random pixel boxes showing up on desktop

Attaching a pic of what happens on my desktop. I'm assuming it's something to do with my graphics -- sorry but I'm not too savvy on these things. Any suggestions? I also get these online while on FB or other photos.

Artifacting. What graphics card do you have?

Do you have switchable Intel graphics too?

Yes, Boozad, I have switchable graphics. Whenever I unplug or plug back in it asks me if I want to switch, which I do. Some one also mentioned it might be an over-heating problem too. Seems the fan is always running when I'm browsing online.

Download Speccy linked in my sig to check your GPU temperatures. Do the boxes show up when using the Intel graphics or just when using the Radeon graphics? And when you say 'whenever I unplug or plug back in it asks me if I want to switch' what do you mean by unplug or plug back in? The mains lead? External monitor?

I'm not sure which graphics are being used when. It will ask me to switch when I change my laptop from A/C to batteries (unplugged) or back again. No separate monitors. Browsing driver updates online -- maybe that will fix the issue.

White boxes on desktop shortcuts
I find these white boxes on top of my desktop shortcuts. Have a look at the CCleaner shortcut in the photo, that's what I'm talking about. How can I fix this problem? P.S. Please don't suggest sfc scannows or resetting iconcaches, I've tried them both.
