A problem I’ve been experiencing for quite a while on my computer is that dialogue boxes have been very slow to open in MS Word and Excel. I assumed it was a result of the UBitMenu, a handy add-on that restores the old-style drop-down menus we used to use before Microsoft introduced the awful ribbon. I accepted it as a trade-off, since the delays were more than offset by the time I gained by finding option quicker thanks the drop-down menus (and being able to open up the drop-down menus thanks to a script I wrote).

But then things started getting really slow, and I’d also experienced some sluggishness in my browser. I trawled through the forums and found many people with the same problem, but nobody was proposing a solution that worked.

Then I read a post by someone who hypothesised that it was down to hard drives that were dying. The writer of the post (which I can no longer find) had the issue on two computers, both of which then experienced hard-drive failure. He then started working on a laptop that was more than 10 years-old, and therefore should have been much slower, and found that he no longer experienced the problem.

The hard drive that came with my computer has been playing up recently, with one of the partitions not working very well. Fortunately, I only use it as a backup drive, as I migrated my operating system and documents to a solid state drive several years ago (I recommend all my colleagues do the same, as will make your system much quicker), but it seems that even having the hard drive connected was slowing down my system, especially (for some reason) when opening and closing dialogue boxes in Word and Excel.

If you are experiencing the same issues, try disconnecting any old drives that no longer perform properly. Of course, if it’s the drive that your operating system is running on, then you can’t just disconnect it, but it’s a good excuse to buy a solid state drive, which will definitely speed up your system, even if it doesn’t fix this particular problem.

If, like in my case, the hard drive playing up is one that you can safely disconnect, but it is an internal drive, you don’t need to get out the screwdrivers. You can simply go to the device manager, select “Disk drives”, then right-click on the device that’s playing up and select “Disable device” (whatever you do, don’t do this on the device that runs your operating system!). After restarting your computer, check whether the problem has gone away.
