I have a AJP 3Ghz laptop - just less than a year old - and I never get blue screens!!! So what am I complaining about??? If I use a CPU intensive app, such as a codec or a zip (?), the computer switches itself of, completely. This usually seems to happen when it gets hot.
Would it be worth reformatting to try and solve this problem?
Don't have a laptop, so not entirely sure if am able to help. Does this happen when using the lt plugged into the mains, or only when running off the internal battery? 3Ghz should be ample for multi-tasking, but maybe something is running in the background and using too much of the cpus' resources.
