Sorry for the delay in replying. Just came home from a very exhausting and stressful day at work. :p Anyway, I haven't had a chance to try Karen's suggestion yet, but I will. Trenna, I regularly use Microsoft update and it didn't do anything. Jen, my reboots tend to coincide with the moment I shut a programme (such as closing the last Internet Explorer window open).
Jose, my video card (not sure it's what your asking, but you'll tell me) is a nVidia GeForceMX 100/200.
