It's barely over a year old, running Win XP. Though after all this happened it the video card decided to die.
Sooooo, I have no clue if that can cause the sluggishness that I was experiencing after I installed some programs (updated AVG from 8.0 to 8.5) or installing Runes of Magic. Those were the two programs I installed when my computer started being sluggish. Programs would load slowly, My Documents/Pictures etc would take like 5 seconds to load.
At least I think the card died. The BIOS/boot up screen is pixelated/blocky and my resolution is stuck at like 640xwhatever. I tried to install new drivers and it said it was unable to detect any devices.
