I am running a Lenovo thinkpad T60p, WinXP SP2, 1 GB RAM, dual core processor @ 2.16 GHz, ATI MOBILITY FireGL V5200 video card.
I am certainly not trying to run Half Life 2 on my laptop, or watch super HD-DVDs. However, even the smallest exertion of video graphics or even online game turns out to run pretty slow, sometimes lagging. online videos full screen consistently lag, while resizing to a smaller window usually helps them run faster. Flash games run pretty slow, and changing the setting to "low quality" usually helps a bit. Laptop was purchased 2 years ago, started noticing these problems about 2-3 months ago.
Why is my laptop incapable of running even simple videos and games smoothly? How can i isolate the source of the problem?
