Windows 10: "System" putting my pc at 100% disc usage constantly

So recently, I've been experiencing so much lag on my system, that it even makes my cursor frame skip, and now, it isn't a bad pc either. So, I checked task manager to see what was going on, and I was at 100% disc utilization. The only thing that was doing anything above 1-2 MB/s was the system. It usually sits at above 10 MB/s, and at maximum, around 40 MB/s. I have a decently old hard drive that was pretty cheap when I got it. I'm just curious as to what might be happening, and if it's just that my HDD is on its last stretch of life. It only happens when I have stuff open. It's never happened when I don't have 2-3+ things open, whether in the background or not.

Disc Usage at 100%

Hi Andre,

Thanks for getting back to me.

I started going through your list of suggestions.

I have switched off all background apps. I was horrified to see so many.

I then disabled windows update.

At that stage I thought I would check out disc usage on task manager.

Disc activity had gone down dramatically and in the performance tag activity was very low, it spiked from time to time if I did something on the PC but the speed on all activity was back to normal.

I thought I would leave things as they were and see if things stayed the same.

No problems at all until this afternoon I was trying to look at a file via windows explorer and got the message "not responding". A quick look at task manager and disc activity is 100% again. Everything slows down. I close down some screens and the desk
top turns black.

The only way I can get a display up again is "alt" + "tab". The task bar has disappeared. I decided to reboot but the only way I can do that is with the on'/off switch.

The PC reboots. I check that all the apps are still switched off and windows update is still disabled, Disc activity is still 100%.

As I type this disc activity has suddenly dropped. it keeps spiking to 100% but then reverts back to about 12%.

Is this normal or is there something else I should do.

Back to 100% now. How do I find out what is actually happening, what activity is the disc doing?

I am confused.

Any suggestions?

100% Disc usage when starting the PC

Hi Dave,

thanks for your fast reply.

The top 5 processes change all the time.

But the most often ones are:

System

Antimalware Service Executable

Chrome

Malwarebytes Service (It is doing a search right now)

Service Host (a couple different ones)

EDIT

The Malwarebytes Scan is done now but still in the top 5.

The disc usage went down to a decent number so I started a steam update to see what would happen, Results:

Steam is now Top 1 with around 60MB/s, disc usage is constantly on 95%.

Second EDIT

Steam is still updating but the disc usage is now on a constant low like 4-15% so there has to be something else bothering my pc, right?
