A few months ago my video card began overheating when I was playing World of Warcraft. It would freeze and the screen would become a multicolored pattern, and sometimes just restart. I monitored my temperature levels around 120 C. So I dusted my video card, got a GPU cooler and some more case fans. It didnt go above 100 C again. However, after a few weeks I'd still crash to the same kind of multicolored pattern, except it would recover after a few seconds and the game would keep running but with graphical issues, like spears of color coming down all over the place and moving around. Then one time it crashed, and i tried to turn it back on. It would power up but it wouldnt beep at all and the monitor would be blank. I was broke at the time so I just let it be and used my laptop for the time being. I recently got some money so i tried to start up my desktop again to see what would happen, and it turned on. It started up fine, but World of Warcraft crashes to a multicolored pattern for a few seconds then resumes with graphical errors like it used to, and my sound makes the static screeching for a few minutes. After that I can play a song in Winamp fine, but before then it won't even play. I tried to play another game, Hitman: Blood money, and it froze when I tried to alt tab. It just froze, no weird graphical errors or sound, and I couldnt do anything except a hard restart. If i had to guess, I'd say its my motherboard cuz my friend said MSI sucks.
