Vaios have something which is known as "sleeping sickness" .. they last initially for about a year before you have to get them returned to base as they just start to shut down .. they overheat due to shitty heatsinks used (which although helps their parts and support) does nothing for the end user. You can buy these decent hezatsinks and get them put in for you to remove this problem as Sony sure as hell wont put them in. That said, Toshibas / HP / Alienware seem to be the most stable at preset ..
