That's sad to hear, I hope you don't have any issues with whatever system you decide to purchase
In 25 years of PC ownership myself, having in that time owned I'd estimate about 12-15 PC's and Laptops, and being the designated family/friend support person for another 15 or so during that time, only one of them ever had an issue with overheating - my mother's 2011 PCS mini PC. It wasn't any kind of cram-it-all-in overclocked beast either, it was an off-the-shelf standard offering. Of those 12-15 PC's I've had myself, 3 of those were self-build with the fastest (reasonably priced) components and sometimes overclocked. My current self-build from 2011 which is rocking an i7-2600K @ 3.6GHz with 16GB of 1600MHz DDR3 was back then a beast but is now just a good performer, but it's never spent a minute of these 3 years behaving oddly in any way.I do hear that only PCS PC's generate heat
So you can see why when I come looking in the forum with a question I was about to ask about illuminated keyboards and whether you can get one on the Optimus V, the first thing I see is overheating stories, my first thought is uh oh, not again. I'll feel safer I think with something like a Dell, or Asus. It's sad, because I'd really like to spec up an Optimus V to about 2 grand and retire my current desktop completely.
