Around 2 years ago, I purchased a Sony Vaio AW390 (6GB RAM) which btw costed me around $2,900. Naturally and for that price, I expected a stellar performance on my laptop. Unfortunately, today, the CPU overheats so much that after I use the laptop extensively (especially in gaming mode), the graphics start to freeze up/glitch, the whole cpu speed becomes reduced to half of what it used to be and on very rare occasions the laptop restarts by itself.
I attempted to clean the fan without opening the laptop with one of those AC power blowers and things slightly improved for a while only; a few weeks later, the same symptoms re-appeared and it's really getting to be a frustrating thing, especially for the price I paid.
I purchased one of those cooling docking platforms that you connect via USB to your laptop and again it helped a bit but not the speed I am looking for.
Thank you very much for your prompt reply; will definitely do that as the laptop has become unbearable; I am actually considering switching back to Apple's new macbook pro which used to give me no problems at all no matter how much I used it (day and night). Will visit Sony repair shop nevertheless.
