Windows 8.1 Disk 100% usage

[olivergejsoe]

For several months now my PC will randomly spike to 100% usage on the Disk department, effectively slowing my PC down to a crawl and I can't find the solution for the life of me.
I must have been through hundreds of forums trying to solve it, but none seem to have worked whatsoever.
I'm not very good with computers, but I'm basically at a loss as to what it could be, but I've been following guides on how others solved it and none have worked.

I ran and HDDscan and everything looked fine apart from "ultradma crc errors" which I have no idea what means or implies. Please help

Consider upgrading to SSD.
Currently there are several windows services capable of causing 100% HDD usage:

• windows updates;
  windows defragmenter;
  malicious software removal tool;
  windows defender;
  search indexer.

Udma crc errors may signal about bad hdd data cable, overheating of storage controller on motherboard or overheating of hdd itself.

I'd suggest upgrading to SSD.

If you wan't to find out, what exactly is causing 100% disk usage, you can do that with Resource Monitor - disk activity section.
