Aah, defrag software. Once an essential part of any computer maintenance. It could help speed up opening programs from thirty seconds to fifteen - an increase of 50%, simply by making sure all the 'chunks' of the file were together. Back in ye olde days, hard drives spun a lot slower than they do now and access times were a lot slower, so if a hard drive had to read ten chunks of a file, it would take ten disc rotations at least.
Nowadays, drives are a lot quicker, with 7200 RPM drives the norm (assuming non SSD drives) with most having cache memory included, plus speedier access times. If you've an SSD, then you've even quicker (if not instantaneous) access times.
This all means that defrag software is all but unnecessary. There would be negligable benefits obtained from running the software.
Aah, forgot to mention that drive sizes have also increased and NTFS is the norm in file systems. This also reduces defragmentation. Years ago, a drive would have to write a file, and it would start saving it at the beginning of the drive, utilising any free space it found. This caused defragmentation, as nine times out of ten, the size of the file would be larger than the free space block found. The drive would have to find the next free block, and so on. Fragmentation. NTFS improved this as it knew the size of the file to save, it would find (if possible ) a free block the required size. Most users these days have GB's of free space, so finding a free block is nearly guaranteed.

Save your time, save your disk space and don't bother installing this - it really isn't necessary ... especially if you have an SSD. If you don't have an SSD, then look at getting one - they're dirt cheap these days and can dramatically speed up your computer*.

* Capacity compared to normal drives can be reduced though, but for most users, 120 GB or 240 GB is plenty...

Redphantom, there would be no reason to get a blue screen of death from a fragmented drive - thats not how it works. What has probably happened though, is that you mention your drive is making unusual sounds. A portion of your drive is physically damaged. By defragmenting, you've moved data from the damaged area to a non-damaged area.
I would recommend using Macrium Reflect to create a drive image - your drive is on the way out and could fail at any point. Don't leave this - the longer you leave it, the more chance you have of your drive failing - if Windows stores a vital file in the damaged area (which is now available) and cannot access it later, this is where your system becomes unusable.
Buy a new drive ASAP.

Redphantom, what may have happend is you may have had damaged sectors and or filesystem and when you defragmented the hard drive it force remapped the damaged sectors or ran chkdsik with fix option prior to defragmenting which may have resolved the problems you had been experiencing but hard drive fragmentation on its own cannot ever cause a Blue Screen Of Death or any boot failures.

IF a defragmentation process takes over a week to complete it means the hard drive is failing badly and having to do many retries to get anything done. seriously consider imaging the system and or copying the current system to a new drive and things will really improve!

Chris, while I agree about the SSD, if you still have an HHD, you still need to defrag it. I thought my windows defrag was taking care of it automatically. I was wrong. My drive fragmentation was over 80% when I realized it and not only was the computer running slowly, the sound wouldn't as it should, I was getting BSOD, and it oftentimes wouldn't boot. Somehow, I realized it needed a defragmentation, which took over a week. Now the computer runs much better.

Windows 10 has a built in tools to defrag HDD disks and optimize SSD disks. They are mostly automated. The game defragment affects only loading times if game is installed on HDD. SSD is so fast there is no need to optimize neither a game nor disk very often.
