    Disk at 99% even when nothing is running, slowing down PC?


    Hi guys,
    I got a brand new Toshiba Satellite p50t-B01E 2 days ago, runnings windows 8.1. You can see the specs of it here: PSPNVA-01E00N - Toshiba Satellite P50 Computer - Australia :: Toshiba :: Computers, Laptops/Notebooks, Tablets, Televisions, DVD and Blu-Ray Players, Camcorders, Storage, Accessories, and more


    I have only installed about 3-5 programs, and you can see at that link it is a very powerful machine so I don't know what the issue is. Right now it is fine as I'm only running chrome. But when I open photoshop or another program everything becomes VERY slow, glitchy and has recently started to freeze and I can't click anything or even get into my task manager (task manager screen doesn't even load, it just turns black and gives me an error then returns to my desktop).


    I closed a few things, restarted and then finally got task manager to open only to discover my disk is at 99%?? With only one program open! Here is a quick video of what my task manager looks like... disk problem - YouTube

    In this video, at around 1:56 in, you can see a Norton popup in the right bottom corner. This said "High usage by Host Process for Windows" or something like that. I can see this in task manager but I'm not sure what it is and if I should terminate it or not? It seems to just run on it's own, so I imagine it's important? But is there a safe way to disable it without harming my machine?


    It's getting quite annoying. I bought this thing for it's power and that is something I am definitely NOT getting. Please if anyone can help that would be greatly appreciated (btw I've already tried disabling the "super tech" and "windows search" services which is a potential fix floating around the net for this problem, but it unfortunately did not fix mine)

    Regards,
    Bec

    Looks like I'm having the same symptoms as you. I've tried every fix out there, and still no luck. I've tried stopping the services, disabling windows defender, disabling my disk drive, updating all drivers, the trick where you increase the memory settings, everything, and I am not able to figure this out.

    Have you tried updating windows?

    That's unfortunate well, since I got the laptop last Wednesday night it has done 2 lots of automatic updates. First lot was 77 updates then the next was 50 so I'd want to hope it's up to date! (Iit's fair that there were this many as it had been sitting in storage for a while).

    I have just clean installed windows 8.1, without any update and I'm still getting these freezes. I think the only solution for now is to go back to windows 7 until windows 10 comes out

    The video shows that C: is full or nearly full -- which is going to slow down Windows to a crawl!

    If you've been downloading lots of stuff to C:, the short-term solution is to connect an external USB drive or USB stick and move that stuff OFF your C: drive to make some room.

    Your processor, according to the video, is only averaging in the lower percentages -- so it's not a processor bottleneck.

    Thanks for the help, but that isn't correct. This laptop is brand new, has a 1TB hard drive and here is a screenshot of how full it is: http://s13.postimg.org/4a7kd9iyf/drives.png
    You'll see I also have a 4TB WD My Cloud home NAS server connected in order to keep my internal hard drives free of excessive data.

    My processor is also i7, so it is a decent one. It may not be an overclocked gaming version but it should still run very efficiently and it is not. See here: http://s13.postimg.org/48t163rqv/pcinfo.png

    It seems it is the processes that are causing this... I apparently have very high usage from something called "Host Process for Windows". Does anyone know what this is and if it is safe to terminate it, and if so how can I permanently terminate it?

    Yeah it's normally at 0%-1%, and runs perfect, then when this happens it ramps up to 100%, and the PC is unusable.
    Here are some suggestions that didn't work for me, but may work for you:
