Graphic problems

Obligatory, "are your drivers up to date?" query.

Edit: I'm also on a shitty monitor at work, where are the pixels in question? I don't see anything noticeable

Try to plug and unplug the video cord, maybe is your monitor that's old too, but old Video cards tend to rust in the PCI/AGP or video connection, also PCI/AGP motherboard connection can too.

Edit: I don't see any blue pixels too, so what monitor you have?

what blue pixels ? i do not see any in the image u posted i think its ur monitor issue

What blue pixels ? Videoram is dying.

You need a new graphic card.

Also, what blue pixels? I cant see them

I can't see anything out of ordinary in your screenshot. Can you outline parts where those blue pixels appear?
One possible cause may be your cables. Did you try it with a different monitor?

can't see anything wrong in the image

I don't even see any blue pixels, screenshot looks fine to me.
