What do errors do to a computer?
There are several things that errors can do, which amount to
glitchy and slow computer performance and programs failing to work.
If a graphics driver is in error, you might see weird things
happening to the display, if a core program .dll is in error, the
program won't work, etc. Get a bunch of errors, or just a few of
the right kind of errors, and your system will crash, showing you
the Blue Screen.
