The amber-colored LED on the front of my cabinet is blinking frequently. This doesn't happen normally. What does it mean, and what should I do?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
By "cabinet," do you mean the plastic or metal tower that contains your computer's guts? There are two common lights on computer towers: power and disk. Power is generally green, and doesn't blink. Disk is sometimes orange/amber, and blinks when your hard drive is in use.
It's not uncommon for the disk light to blink rapidly when you're accessing a lot of files, or one big file. Your symptoms could be caused by you or one of your programs looking through the files on your hard drive more than usual.
Probably some program is writing or reading a lot of data on your hard disk(s) or something running on your computer has totally filled the amount of usable ram on your computer and your hard disk is swapping. If you use Linux you can try reducing swappiness to increase the usage of ram. You can try a antivirus/antimalware scan or you can buy much more ram :-)
