Is the machine generally slow when this happens ?
If you start using another program, is everything slow. Or
does the slowness only happen in the Facebook window ?
If Adobe Flash is involved, there is a tick box to
disable "Hardware Acceleration" in the Flash window.
Right clicking in the window, may bring that menu up.
That's the only setting I know of, that makes a difference
to Flash.
(Untick the "Enable hardware acceleration" box)

You can use Task Manager (control-alt-delete or right click the
Task Bar and get Task Manager from that menu). The performance
graph, shows how much processor is being used. If the graph
was running at 100%, then you'd check the process
list to see which program was using the CPU.
You could find, that CPU usage is close to zero, and yet
the keyboard is slow. Key presses are "Events" and get
passed up the chain as they're processed. It's possible
to install a "filter driver" or "shim", which intercepts
the stream of characters. An example would be a keylogger,
which is a kind of malware used to steal passwords. So
there can be reasons for the slowness, if a filter driver
was interfering with the operation of the keyboard. But then,
you might experience symptoms across all programs, if that
happened.
I like your Adobe Flash theory, because that is self contained
enough, to make trouble just in that Window. But watch the
Task Manager, and see if the processor is busy or not.
Another tool you can use, is Sysinternals Process Explorer,
which will also display the Interrupt rate. If there was
a hardware failure, and a lot of interrupts, you get
an "Interrupt Storm". That eats up CPU, with no guilty process
showing in Task Manager. If you use Process Explorer, you
might be able to detect that kind of failure. Such a failure
is pretty obscure (not seen very often).

In this screenshot, you can see the Interrupt rate is using
barely any CPU at all. Each time an interrupt happens, kernel
level code services the interrupt. And a high rate of spurious
interrupts (interrupts unrelated to user activity), can soak up
all of the CPU.

Another question for you. Did you install the "keyboard driver"
which came with the keyboard ? As a rule, I *never* use the
CD that comes in the keyboard box. And if Windows Update
offers a driver, I don't accept that either. The "extra keys"
on the keyboard might not work, but then, I'm never bothered
by bugs in that "free" software. I like my keyboards to work
with nothing more than the HID (human interface device) driver
provided by the OS. Sometimes, that software, for turning the sound
volume up and down with "multimedia" keys at the top of the
keyboard, is buggy stuff.
