One of my clients has a Toshiba laptop,celeron processor,4gb ram,500gb drive,it's 5yrs old came with Win7 but he's upgraded to the free Win 10 about a year ago.
The laptop has slowed considerably the last few months, he only has 40gb free on hard drive,ive run Disc clean up it recovered 200mb,and Ccleaner 450mb
I've noticed there are no restore points created and asking it to create one results in a blue spinning circle,I suspect the hard drive space is taken up with a Windows 7back up that I found but that doesn't delete either,blue spinning circle
Does it run ok in Safe mode. If so possible curupt or unsigned driver could cause slowdown.
You could also try deleting the W7 back up file while in there to see if you can get it removed.
5 year old laptop so hard drive will possibly be past its best and could be on its way out.
Obvious solution would be new hard drive with only W10 on it.
I bought a brand new laptop last year with nothing hardly on the hard drive and it ran as bad as the one you are working on. never ever found out why it was so slow. Gave it to my daughter and she seems quite happy with it.
Hope you manage to solve the problem. I suppose you have tried running sfc /scannow to see if it findas and fixes any corrupt files.
Thanks for the info,I've been unable to remove the windows 7back up,when I run the disk cleanup tool it doesn't even show up,I right clicked on the back up but that just resulted in a blue spinning circle,I haven't run SFC I didn't have enough time but it's something else I can try next time I meet up with the client
I know seems bit strict but we're not allowed to advise on upgrades in case it leads to that person upgrading the pc and seeing no improvement,we just have to do what we can until there's a definite hardware problem
The windows 7 back up file is taking up 29gb of space,still using safe mode and running disk clean up couldn't find the Windows 7 back up,so ive been unable to help the client with this
Also ive run sfc /scannow which found no problems
I have recovered 9gb,the client had a folder with media content in which he didn't need anymore but I would still ask if anyone has an idea why the Windows 7 back up file doesn't show up using the disc clean up tool?
