My PC getting slower and louder. Even the simplest tasks, such as opening a browser window, lead to an onset of whirring and clicking from the hard-drive and a ridiculous wait. It's too old to to make arseing around checking and replacing stuff worth it economically it's easier getting a new one as I don't need high end specs..
But the absolute ball-ache of installing and setting everything up again on a fresh system just means I'll persist with this frustrating heap.
The HDD is likely on it's way to the grave...back up important files and move to an SSD, if you can. The fact you're still on an old drive, in this day and age, is criminal if only for the speed difference. I would not suggest doing what
@chrismpw mentioned (sorry, mate) as it could be the write arm that's going out and a defrag will just stress it and may lead to an earlier retirement. The clickies is almost certain death sooner or later; abandon ship. Multiple ways to do it, some more economical than others. Also, do not shut it down if you can.
The backup and the ssd are good shouts. Transforms any old pc. I suggested the defrag as an easier and cheaper option. Have to say though that in 33 years of having a computer with various hard drives at home I've only ever had 1 hdd fail on me ... and that was because I knocked it off a table.
All good posts. I've got multiple computers on the go. Like Claus, sometimes i really need the exact same operating system/programs/files so a fresh installation is a balls-aching last resort.
First thing is to make sure the problem is the Hard Drive, and not software (OS, applications or viruses) or other hardware (RAM, CPU, Fan etc).
Here, in a failing Drive scenario where you want to keep exacty what you have, best bet is to:
1) create Image of your OS and save to external drive.
2) replace knackered HDD with brand-name SSD.
3) put Image into SSD.
You'll have effectively the exact same Windows: programs, files, foibles and all. I've used this method for continued long-term use of very specific installations.
Haven't done one since 2018-ish, so best to check updated user guides (as Windows 10 changes so frakking often).
Note: the Image solution only works if the host-computer (or laptop) is the same (or close enough). The imaged installed-OS won't recognise a new laptop, especially with different-brand motherboard.
