When you say something is "necessating very frequent reboots" what do you mean? Why are you having to reboot.. are you actually being prompted/forced to reboot?
Thanks, rridgely, for suggesting Dial-A-Fix. I have never used this, but I'll take a look at it. I assume it's fairly straight forward and fairly safe to use. Is there anything in this program I should NOT use?
In response to your question, I intentionally avoided being too specific because it's a little hard to describe -- but, yes, I am being forced to reboot.
Basically, what happens is that everything runs just fine -- then very abruptly (at least once a day) the overall responsiveness deteriorates significantly -- everything becomes very very slow (switching screens, loading programs, etc.) -- then I notice that some of my screen graphics aren't filling completely -- and that's about the end -- it just freezes and I have to reboot. Once I reboot, everything is wonderful again

until the next time.
To put it another way, it just seems like something gets all "clogged" up -- that my computer just can't deal with any more stuff (whatever "any more stuff" is??) -- and the reboot just cleans it out.
