Blue pixels on my screen

I am not quite sure what the issue is, but I really need to find out. I just bought a new monitor and for some reason I am getting flashing blue pixels in random spots on my screen, it seems to be in places where there are grayish colors. I have tried taking a screenshot and they dont show up in the picture so I dont think its my monitor.

This is a custom build pc and its my first so I could have done something wrong. I am not sure if its my graphics card or what the deal is. I have checked my temperatures to make sure it wasnt overheating. and my graphics card is fine but my processor is hitting around 80 C or higher (when Idle). I know that is way too high. I just dont know what to do at this point. could anyone give advice on anything I could do or what my problem could be?

yeah it isnt stuck pixels. :/ Its like blinking ones all over. what do you think i should do? just return it for a new one?

havent tried changing the refresh rate,

right now im on an hdmi connection, earlier i was connected to a tv up until i got my new monitor, and the tv wasnt doing it to my knowledge. I will try the vga connection after I try changing the refresh rate, (for refresh rate, would it be in monitor options or my computer options?)

I tried connecting my laptop and the pixels were gone so I am fairly sure it isnt the monitor. (unless my laptop being a lower resolution would make a difference?)

I am hooking up my desktop now, Cabels I am connection are DVI (I dont know what that does, Do I need it connected?) plugged into my graphics card, and then a VGA cable plugged into my graphics card via a DVI/VGA converter plug (my graphics card, MSI N560GTX-Ti Twin Frozr II, has two DVI ports and a mini HDMI.) and I will see if it changes from the hdmi

no i connected my laptop to my monitor via HDMI, to make sure it wasnt the monitor (I just extended the display) and the pixels werent there, so I dont think the monitor has an issue, (like i said Idk, if the laptop having a lower resolution would change if those pixels are there).

ok i booted up on my vga input. but as soon as it got through startup, it switched to my dvi, am I supposed to only have one of them plugged in?

anyway, I am on DVI now and the pixels arent there yet, but i think they didnt show up before until the computer had been running for a bit, I will see what happens though.

I tried running a game (audiosurf) and its running amazing so far. I think the problem could have been as simple as switching my video cable!

everything looks great, blue pixels gone! but my gpu is running around 45-55 idle and 55-70 running, is that normal? I could arrange parts in my computer better to get better airflow. but id rather not if that isnt too bad.
