my computer keeps crashing... "not responding"

If it's over 6 months old, then it's really old stuff!

So, you may wish to update and replace Everything!
Processors are 83 times faster now and 45 Tetra-Bytes of Disks are like $5 extra!
And they put entire Clouds into them I hear! And Cloud is a bunch of storage!

Get a Blurtooth Keyboard and Mouse so you can forget to charge them!
