|ok, from what I can gather the reason why outlook was crashing was because the CPU was at 100%, and that little green square was the task manager (usually launched by pressing ctrl+alt+del) showing that it was at 100%|
from what I can guess that intel desktop board screen is the BIOS. Have you tried pressing F1 - F12 or the delete key to see if you can get into the setup, if so is is displaying any errors?
finally, is the computer beeping at all, or does the power light or the keyboard lights flash in any unusual way? This could also be the computer trying to say that something is wrong.
