My computer is fairly old. I think I build it at the start of 2009, and it's starting to show its age.
Since the day I built it, it's always been fairly loud but I've never thought anything of it since I'm always wearing a headset when I'm near it. It's also always had a habit of crashing the graphics card for me. Since day 1, if I'm watching a video or playing a game I'll just have the 10 second blackout and flicker with "Your graphics card stopped working, but it's okay again now". Me being me, I've always forgotten about this 10 seconds later - I'm in the middle of [a game|a movie] man!
Recently, things have gotten worse. My computer will just suddenly stop everything it's doing; the monitors get no signal, the drives stop spinning, all input is dismissed and it acts as though it's powered off with the exception of the case fans which are going crazy. I have to hold the power button for 10 seconds to turn it off "properly", then when I turn it on it does the exact same thing immediately. Turn it off again and turn it back on, and it's fine again for 30 minutes.
I've asked lots of my friends for advice and we all came to the conclusion that it's overheating. Seems obvious now, but it's nice to have group support. To verify this, I installed MSI Afterburner and restarted my computer to see what's up. The results were... quite interesting.
As I write this blog post, my GPU cards are at 85°C and 87°C respectively. The only applications I have open are chrome, XChat and MetroTweet ...
