Unrequested sleep when typing with Vista

Is this a power issue? I have replaced the harddrive, reloaded everything twice and now I have this problem again. Could it be heatsink? fan? Where do I go from here? or is it a driver issue?

This is either a power or heat issue (not Vista). Are you overclocking anything? If so, stop until you figure out what is going on.

Please describe your system, to include CPU, video card/GPU, motherboard (make/model), memory, HDDs, optical drives, PSU (make/model), etc.

Please clarify.
