Hiya,
So recently my computer has been suddenly freezing and then crashing and im not sure why. It only occurs when im doing something visually intensive such as playing a game or watching a HD video which leads me to think that its to do with my graphics card. I have tested the temperature of the graphics card and its usually about 36 degrees celcius.
So im at a loss here and its really annoying. Can anyone help please?
 
Oh right thank you for replying! Would you suggest that I have my PSU checked at a local computer shop or just buy a new one? (I have never done anything with a PSU before).
