Is my hard drive failing?

[GGtW]

For the past couple months I've noticed my hard drives, both, have become fairly noisy. Programs, games especially, don't seem to run as ****, and choppier. And the most annoying is my windows boot time is up near 3-4 minutes. Never was like this. These hard drives are about 2-3 years old maybe.

I've run several Spyware removable programs, defraged both drives, to include: Spybot S&D, Ad-Aware, RegScrubXP, Cleanup!, ATF-Cleaner and AVG Virus Scanner.

One is a Western Digital Raptor WD740GD 74GB 10,000 RPM SATA-150 Hard Drive
Other one is a Maxtor DiamondMax 10 6B300S0 300GB 7200 RPM SATA-150 Hard Drive.

The 74GB Raptor is the one Windows is installed on.

Here are some graphs of both hard drives under DiskSpeed32:

1. Back up your data.
2. There's always the tried and true fix - reinstall Windows.

My windows was install less than a month or two ago when I replaced my video card and procc.

All my data is backed up.
Ran check disk, the program that windows offers to check your disks; both passed.
Ran the Western Digital diagnostic program for the hard drive; passed that as well.
Is it just coincidence that they're making more noise then usual and are not the problem here?
Any other suggestions? Maybe bad ram? The video card is about 2-3 months old...
