台式机显卡也有问题，但是不像笔记本电脑的散热问题那么严重，因此损坏的概率低。

This is a heat related issue with the bonding substrate used in the manufacturing process. The thermal tolerance for these materials was lower than what the specs required and can not handle the hot-cold-hot-cold states caused by power cycling the computer as well as voltage variations by the power management software. Notebook users are seeing failure sooner than their desktop counterparts specifically because of these reasons. ("usage patterns" mentioned in the 8k report)

所用的材料无法达到足够的热稳定性，笔记本电脑通常会比台式机更频繁地开关机/休眠，所以更早发现损坏。

Defective Nvidia chipsets in your current Vaio?

---

Nvidia investors were just informed that the company is taking a $150 to $200 million dollar charge related to "higher than normal" failure rates in notebooks for it's (unspecified) "previous generation" GPU and/or it's thermal system.

Update:

The Nvidia G84, G84M, G86, and G86M chipsets (GeForce 8 series, GeForce 9 series) have been identified as the ones that are defective. All of these chipsets (both mobile and desktop) use the same application-specific integrated circuit. It is possible that the G92, G92M, G94, and G94M chipsets are affected as well. The Inquirer has confirmed the issue also occurs in GPUs as recent as the new G96M chipsets.

See the list below for actual models that may apply to you. It appears to be specifically related to revision A2. The problem has not been reported with revision A3 and upwards.
