hi again. Sorry to double post (as a matter of fact, if a moderator would merge the messages, that would be great), but it has come to my attention that this issue could also be a result of overheating. I would like to explore this option. Please download and install SpeedFan so that we can monitor your PC temperatures. If you're not sure what SpeedFan is, here's the developer's description... "SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips." There's much more to it, but I don't exactly want to lecture you either lol Here's some more information if you would like to read up... http://www.almico.com/speedfan.php
... Once you run SpeedFan, post back your results. Let it run for a little bit though, this way we can see if it changes in an eratic way, or is just fine.
