    resources at 100% even when nothing is running

    Checking through the list doesn't reveal anything, but it's still 100%.

    What made you check the Task Manager?

    Even if I scroll down everything isn't using any resources.

    I checked task manager to see why programs were taking a while to respond, like actually clicking on the start menu causes a noticeable delay while it opens.

    I would start with disk.

    First I would run chkdsk /r
    I would also get a tool to look at disk health, most drive providers have their tools or crystaldiskinfo Crystal Dew World

    Have you checked for virus using a second set of eyes, something like malwarebytes?

    You could also click on the performance tab in task manager, then Resource Monitor link at bottom of page. Click on Disk Tab when window opens. Then in the Disk Activity section you can sort the reads and writes looking for heavy hitters.

    If you want a more advanced tool to track down usage, you might want to try Sysinternals Process Explorer. It's free & gives detailed information.

    You can also use it to check all processes to see if there is malware present. Go to Options/VirusTotal/Check Click on it, accept the agreement & it will show the results in a column on the left.

    The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

    The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.
