Hard drive issue/Computer incredibly laggy

I have a brand new incredibly amazing laptop I got only months ago.
It's the Lenovo Y50, with the gtx 860m and i7 4710hq.

Anyways, since last night it has been going crazy. I mean, I was playing skyrim and suddenly it just started going crazy stuttering nonstop. Like super fast pulses of stuttering. I thought it was a problem with skyrim, but after closing it to search about it I realized it was my laptop, not skyrim, that was doing this. Browser is laggy as hell but usable, anything more is just unplayable/unusable until i reboot, but even then it goes back to stuttering after a bit.

I open task manager to see my disk activity is at a constant 100%, so I'm thinking this is weird, even when i have nothing big open and read speed says 2MB/s it's still 100%. It's not that task manager bug because the disk light on my computer is also constantly on. Now this has to be my problem, so I run AVG and all their other stuff and it detects viruses and stuff all from this one program (7 trojan horses) and removes them. Didn't fix it until I tried their AVG tune up thing. Not sure if it worked, as after that my disk started reading a normalish amount of activity but still lagging (more on this later). Also rebooted but that doesnt help for more than 30 seconds.

I find out that the manufacturers of the hard drives used on these laptops are poor, and constantly break for pretty much every other owner of this laptop. Whats weird though, is they all report strange sounds coming from their drive (which happened to me on my old mac so I know what those sound like), and I'm not getting any sounds at all. My disk has been running silently pretty much since I bought it. No weird sounds what so ever.

Another weird thing I noticed is after doing all that avg stuff and following guides online, my disk activity is now back to normalish (I think?). its jumping around 0% to 20%, so something fixed it youd think, except the lag is still here. Even typing this right now its kinda stuttery and slow.

One more piece of info is, this pretty much started happening less than a day after I tried to install GTA V. The installation slowed my computer down a ton and took literally like 20 hours to get to even 60% (its a 50gb game) which is when I just called it quits and ditched it. The installer brought my disk to 100% at all times, which is normal id think for a big installer so I ignored it. It made my hard drive very warm though to the touch on that area of my laptop its under, which I thought was weird.

Anyways, I'm prepared to get a new disk, as this ones garbage anyways (5400rpm or whatever) and could get one in about a month from now. (Was thinking a seagate 1tb sshd).

I'm just wondering though, is this (possibly) faulty disk really the problem or is there something else going on?

I'm sorry for such a long story, I really wanted get every detail in there.

UPDATE: After rebooting, the problem is now back in full force with 100% disk activity with NO programs open.

Hi there Azazal,

First of all, as you are facing some HDD related problem, of any kind, I would suggest you to back up your most important data that is stored on it.
Apart from that, in case you have sorted the virus issue out, I would suggest you to consider these two possible causes:

1st one - What is your OS? In case it is Windows 8/8.1, I would suggest you to disable several Windows Services: Superfetch, Windows Search, BITS. Check this thread out: http://www.tomshardware.co.uk/answers/id-2027511/windows-disk-usage-100-problem.html
2nd one - There might be something wrong with your HDD. You can just test it with some brand specific software. The results will show you the overall health status of the HDD. You can run Windows Disk...

Hope this will help,

I solved the problem after looking in my task manager processes. There was a bitcoin miner running that musta come from some recent download, using all my computers resources. Once I spotted it, it was very easy to fix. Just ended process and then deleted the folder it was running from (Hid itself in my league of legends cache folder) and everythings fine now. Glad it wasnt a problem with any hardware.
