A friend of mine got a new laptop recently, upon receiving it he wiped the hard drive and installed a fresh copy of Windows 7 64 bit to have a nice clean install. All of this happened while he was staying at my house for a couple weeks, things seemed fine and we were playing Starcraft 2 and League of Legends together without any issues. The about a week later after everything had been fine he got a lock up, couldn't do anything, just froze and had to reboot. From that point onward it seemed to have been happening roughly once a day. Today, he went home and it seemed to have gotten worse. We were trying to play a game together, and he froze about 4 or 5 times in the span of 30 minutes. He even froze after just booting up and only had Firefox open. It seems odd to me that the problem would escalate like that so quickly. I thought maybe it had something to do with him going home today, and traveling with the laptop. Perhaps the RAM needed to be reseated, or the hard drive might have been damaged? Based on how and when it's been happening, having just booted up, and once while watching a movie using VLC, I don't think it's a temperature issue of either the CPU or GPU. I told him to run memtest and/or reseat the RAM, I think he's going to do these soon and get back to me, but any input from people smarter than me here would be appreciated.
