My Laptop Fan Is So Noisy, Why Is That? And Computer Runs So Slow.

Just replace the noisy fan. While doing so is a fairly easy
operation, it's not always necessary. In many cases, the fan, may just need only a drop of oil. and the computer may be running slow because as you add additional programs, they claim start-up status quickly and
quietly. The more programs you have that are loading at start-up, the
slower the start-up. Remove
the programs you do not want, or are not necessary. It might also be because of the spy ware malicious programs that stealthily embed themselves
into your software. They are installed in your software, without your
knowledge, in many ways. Through e-mail especially.
