Hi. I have recentely built my first gaming pc. I installed windows 8.1 64-bit on it but lately i commonly gets to 100% Disk Usage, making the pc very very slow. Sometimes, even thoug more rarely, it gets 100% ram usage instead, which apparentely is good, but also makes my pc really slow.
Can someone help me with this? My Hard Drive is a 1Tb seagate barracuda. The main problem is the disk part and I do not know if it can be related to the sata ports where things are conncted.
Thank You!

Usage for HDD is not really % filled it has to do with the ability of the drive to complete other tasks. More particular I'd say it has to do with the task queue of the drive being filled up. Basically the computer is giving the drive tasks and that queue is filled during that period of time as the drive is trying to keep up with the amount of work it is being given.

It takes time for a HDD to read especially given the mechanical nature of them. You can think of them working similar to the CD player or maybe more visually like an old record player. The main difference being that the head doesn't touch the drive and the disk spins much much faster.


100% Memory or Disk usage is not good for the most part. Disk usage being at 100% when installing something is understandable though but it should usually flip from 99% - 100% then drop every once in a while. But you should honestly know when it is like this because you would be actively installing something at the time. 100% memory usage on the otherhand is not good at all. Windows should be paging memory to the disk to keep this from reaching 100% because when it is at 100% it means that the OS has no wiggle room to work. Basically at that point the OS has to remove something from memory if it needs more space which is not good.

Like others said you need to find out what on your computer is eating up memory and what is using the HDD so much.
 


First of all, answering to ToineF, no my HDD is far away from full. It has 644Gb free of 930Gb.
Second, I usually open up task manager when that happens, and it takes a while, but the usage of disk isn´t that much! It goes from 7 or so mb to 30mb in very stressful moments.
And ram only goes high (but far from even 1gb total used by programs) when I am playing video games.

 


Two things: best answer was accidentaly chosen.
Then could i be connected to having my two sata 6 ports used by hdd and drw?
 
if you just installed windows 8.x it will attempt to do in place repairs of the entire drive. It will go through your entire drive looking for read errors, when it finds one it will attempt to read the area over and over until it gets a good read, then it will move the data and mark the sector as bad. It does this because people often save time and only do a quick format of a drive rather than a full format which will check and put down new sector markers.

anyway, the repair process does not start until 5 mins of idle and often people have there system go to sleep pretty fast and it ends up taking weeks for what should have taken 5 hours. (depending on the size of the drive). To see if this is the case, you can start up task manager, find the process that is using your disk and see if it is the "system" process. if so, you should power on your system, set it to high performance in the power mangement and let it run idle for several hours.

that being said, I have come across several bugs where the search indexer gets "confused" because some file system problem and basically
runs gets stuck an looping in a sub directory. It just finds the directory, adds it to the index but goes back to the same directory over and over and the search index just keeps growing. To fix this you have to turn off the search index and delete the database and turn on the index service again. If this is the case the index is located at

C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb
and will be very large. (on my system is is ok and is 109 MB in size)

the RAM being full, can be due to a driver problem or the system prefetching programs to put into RAM while the system is idle.
you can turn them off to see if this is the case. http://www.tekrevue.com/tip/disable-superfetch-prefetch-windows-8/

normally you would want them on but turn them off to help isolate what is using your RAM. if you still have the problem after turning the fetching off, you would need to run resource monitor, or look at the memory use of processes in task manager.
 


But the amount of mb being used in total are never that big. This is just me saying. HDD are one of the things i know less about in pcs.

you know, normally when you have background tasks using a lot of resources it's because you have some sort of malware on your computer. My sugestion here would be to clean install windows. start fresh!
