Just got home from work, booted up system and I am seeing hundreds, if not thousands of red pixels lit up...some solid some blinking. Shows up on desktop and most web pages. Funny thing is I came here first because the dark black of this site I figured would help me see it better. But it's probably the only site it doesn't happen.

I am wondering if this could be GPU related rather than monitor. Or even driver. Running a 5850 Radeon. All temps are perfect. I have no problem replacing whichever it is...but I would hate to buy a new display and find it was the card.

Anyone see a display light up with 1000's of red pixels like that before? Ideas?
 
Do have another source to test the display with? EX: another computer or another card?

My guess - its the card.
 
Well I will try this display on another PC , I just changed the driver since I wasn't getting the pixels in safe mode. Still getting them with the new driver...I was hoping it was just a corrupted driver.
 
Yeah if you can try with another PC, do so. red pixels generally mean artifacts which means defective video card.
 
Oddly enough I've seen this occur when a DVI cable isn't connected properly. Chcker yer cables.

Tho it's probably the graphic's card ram on its way out...
 
Graphical artifacts such as red dots and checker patterns are almost always due to graphics card ram failure, usually due to overheating.

The temp shown is for the GPU only not the ram, that card is a few years old so the thermal paste might be dried up and causing a disconnect in the cooling system from the ram chip to the heat sink.
