Wanna know if anyone can help me, this is incredibly annoying.

About ~2 weeks ago my computer started acting up and randomly BSODing. It's happen at weird times, sometimes when I'd leave my computer for a while I'd come back and it'd have done it (usually left Google Chrome, WMP and some other programs open). Then sometimes I'd be playing WoW and it just crashes with no lag, nothing new happening, nothing.

Eventually my computer wouldn't start up, so yesterday I formatted and installed Windows 7. Things were going fine and I have copied across some music and my WoW folder, that's it. Still crashed just now. I'm trying to figure out what it could be. I have a pretty new HD so I hope it's not that, but god damn...

Could it be Chrome? Chrome seems to be the only thing I leave open...
