Laggy PC after Windows 10 and hardware upgrade
Hey Experts,
A client's PC was upgraded to Windows 10 and was not running all that quickly. Shortly after this, a motherboard problem caused us to replace it, the CPU & RAM within the PC. After jumping through the necessary Microsoft hoops to confirm that this was still the same PC and that we weren't doing something dodgy, the PC was re-deployed with the following new hardware:
-Intel i5-6400 Core i5 CPU
-Gigabyte B150M-HD3 mATX Motherboard
-8Gb Crucial (2x4GB) DDR4 2133MHz
The existing case, PSU & 1TB HDD remained in place.
Ever since, the user has been experiencing unusual and moderately constant lag to the point where the PC sometimes takes minutes to simply save a Word document.
HDD testing seems to have confirmed that it is OK, though I am considering retiring the drive for a suitably-sized SSD to boost speed. However, I know that this would simply be masking the issue and I'm not OK with that.
Two issues I'm finding interesting are that, in Task Manager, ...:
1. The HDD usage percentage is often 100% or close enough to that. I've been told the percentages often show as being high in Windows 10, but don't understand why; &
2. The RAM percentage is often 90%+. I have swapped out one RAM chip, but not the other (because one was a lesser-known brand, deployed as a substitute while the Crucial RAM was still being delivered).
As I'm writing now, I realise the obvious reality that I should swap out the primary RAM module to be thorough- I don't know why I didn't think of that before now), but am interested to know if you have any other suggestions.
I hadn't really considered that the mobo might be the problem, but this of course cannot be ruled out.
Interested in your thoughts.

Ram usage sounds suspect, unless the machine has a heap of crappy web pages open or something. What does resource manager identify as taking up the largest chunks of memory?

CompProbSolv & Malmensa, the resource manager says the following (check out the two attached pics):
I did just notice the Speed Boost software on there, which wasn't there before. If our experience is anything to go on, this may be having the opposite affect to its claim. Despite that, the issues and symptoms seen are similar/ the same to those seen prior to any speed boost software bring installed.

Different solutions appeared to work for different users. Disabling the pagefile worked for someone and the problem stayed away when it was enabled with Windows managing it. Another had a problem with an SD card installed. Some had problems with drivers. Take a look and see if any works for you.
Does it do it if you boot in Safe Mode?

Have you installed the chipset and other drivers for the new mainboard? Different hardware usually needs different drivers, so those new drivers should be installed.

Thanks guys.
I'll give these suggestions a try and will let you know how I go.
But just to touch on a couple of items in your collective responses, ...:
1/ The OS was rebuilt from scratch after the Windows 10 upgrade was unsuccessful;
2/ ESET Smart Security and MBAM are installed on the PC and rin-depth scans were run by both programs with both suggesting the PC was uninfected. While I know that no anti-virus programs are perfect, we've used these both for many, many years and have never had significant issues with either false-positives or missing them missing infections (due to the increased performance, though how can you possibly ever be 100% sure); &
3/ All drivers are up-to-date, as you would expect them to be after a fresh installation.

i specificly suggested ram and disk as problem source + how to test them
so i think i am at least entitled to some gratification also

nobus, you're absolutely correct. If you can tell me how to assign a share of the points to you, I'll do so.
hit request attention, and ask a mod to redistribute the points, or reopen the Q

Solution was come to on our own, with assistance from the experts
When the RAM and disk usages are so high, what are the main users of each? This will be the first clue to the problem.
