    100% CPU usage, 100% Disk usage, cooling fans full speed

    Hi guys, hope you can help me please. I'm not too computer savvy so sorry if I'm missing something important or I say something dumb. I'm really frustrated and I'm trying my best to learn and solve this problem.
    So I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
    I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
    What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communications Service...I think it's not related to any process by itself, but its nearly ALWAYS at 100%.
    Finally, memory usage is also pretty high at 78%, but I guess this may be because 4Gb is not too much for this computer. I'm hoping to upgrade to 8 soon. Out of the 10 processes consuming most memory, 9 is Google Chrome (how's that even possible?).
    In case it helps, here's a capture of the Disk Usage stats:

    And one of the processed with the most disk usage and the Resource Monitor at the side:

    Thanks a lot for the help!

    Hi, welcome to the forums,
    Go to Device manager(right click bottom left corner), uninstall the "VAIO care" driver, get the new driver from Sony support:Sony eSupport - Computers - Support
    Install and see whether it helps, check your system for virus infections with Malwarebytes as well.

    Thanks brummyfan, I actually uninstalled Vaio Care altogether form Programs and Features, hope it's the same? This actually did bring down CPU usage drastically, and it's now at around 20% with some 40% spikes, but mainly because I'm running Malwarebytes.
    However, Disk usage is still at 100% and the computer is still sluggish, it's only slightly better than before.

    BTW, Malwarebytes has found 2 infected objects already and I still have to run CCleaner. Maybe this is related, I don't know...

    Windows 8.1

    I had the same problem which occurred immediately after upgrading from 8 to 8.1. I spent a lot of time following suggestions but what rescued me was coming across a post, which at first I thought was a company promotion, saying that CCLEANER would solve the problem with their registry clean-up tool. And it's free. I downloaded the software and ran the registry cleaner three times (rebooting each time) and problem solved. My disk usage is running along at 5-10% and no more time wasted. I was just about to the point of buying a new computer but have to thank this company for saving me the time and money. QUICK, EASY & FREE

    Disk usage on mine doesn't have a performance impact. Maybe you're using a program that's intensively uses your disk.
