Satellite C660 with Windows 8.1 is very slow

I upgraded windows 7 to 8.1 and it was very slow, the disk is always in 100 usage.
When I had the Windows 7 I never had the computer slow.

An entry is listed on your screenshot Tareas en segundo plano de proteccion
Its Windows Background Tasks protection srtasks.exe
This process starts automatically and should not cause any performance issues.
However, in case you have still problems with this exe file, I would recommend you to check the system for possible virus and malware.
Sometimes the viruses look very similar to the standard windows processes an could affect the system performance as well as the functionality.

    How to defrag & cleanup Satellite C650 with Windows 7?

    Hello,
    Moreover I can suggest you to:
    1) Perform a regular disk error-checking (check this as an instruction http://windows.microsoft.com/en-US/windows7/Check-a-drive-for-errors)
    2) Perform a virus scanning with an antivirus e.g. Microsoft Security Essentials
    3) Check you computer for performance issues and resolve them (go to Start => type 'Performance Information and Tools' hit Enter, in a new window on the left side click 'Advanced tools' and review the performance issues enlisted (if any).
    Good Luck!

    Replace the Time Capsule with a new one or replace your router with an Airport Extreme Base Station that has faster Wi-Fi. Or you could just connect your old Time Capsule using an Ethernet connection from the Time Capsule to the computer's Ethernet port.

  • New Satellite C660-1F1 windows 64-bit -cant use graphics editing software

    Hi Guys....any help appreciated...this is the message I sent to Toshiba support but they are taking their time getting back to me:
    Important information: Satellite C660-1F1
    Key Features
    - Genuine Windows 7 Home Premium 64-bit (pre-installed, Toshiba-HDD recovery)
    - Intel Core i3-380M Processor
    - DVD-SuperMulti +-R (Double Layer)
    - 2048 MB DDR3 RAM (1066MHz)
    - 39.6cm (15.6") TruBrite HD (1366 x 768) High Brightness display with LED backlight with 16:9 aspect ratio
    Hi... I purchased my laptop about a month ago from Argos and it has a 2 year warranty. I have one big problem - the 2 main graphics editing programmes that I use do not work. Both Corel Paintshop Photo Pro x3 and Adobe CS5 can both be installed and opened but as soon as I try to save a photo or edit a photo both of the programmes crash and i have to close it down by using end task in task manager.
    This happened when I installed the full versions of both programmes which I purchased and it also happens when you download the trial versions from both the Corel and the Adobe download sites. I have been on so many help forums for both adobe and corel and the most helpful pointer came from one of the designers at Adobe - a Chris Cox.
    He very logically stated that as it happened in both of these 2 graphics editing packages that it was most likely a problem with the graphics card drivers or the actual graphics card hardware. I purchased a 64-bit operating system to handle precisely these 2 programmes which can be exhausting on the system. I know i only have 2 GB RAM at the moment but it has been happening with other people...some who even have 8GB and 16GB of RAM which is what I will have in the next few weeks. However, not if I cannot rectify this problem. Please can you help/advise the best solution. This seems to be a problem only with the 64-bit systems. Both Adobe and Corel are 64-bit compatible.
    There is also a message that appears when I open Adobe Photoshop CS5 Extended....which is as follows:
    ...."Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements, Check the video card manufacturers website for the latest software."
    I then click that message away ....use the programme, edit something, try to save and it crashes. I have gone through all troubleshooting directions and ran countless diagnostics but there only seems to be one common denominator between the 2 different programmes and that is my Toshiba laptop.... I even tried installing another large photo editing software package to test it and I had the same result - an application crash.
    Please help! Thanking you in advance.
    Kind regards
    John

    Hello John
    Have you already got some answer from Toshiba?
    What to say my friend? In my opinion the best advice you can get from Corel and Adobe. They have best experience with own product and have probably tested them on different hardware platforms.
    Notebook manufacturers offer different notebook models with different hardware configurations. Some of them are cheap and offered with average hardware. The performance is not the best but good enough for every day activities like internet, office, mailing and so on.
    On other hand there are notebooks with excellent and powerful hardware. Very often such notebooks cost twice as much as cheap low budget products.
    Please dont understand me wrong but your C notebook is not the best one for usage with such powerful software.
    I really dont know what Toshiba can do about it. I can imagine that you need other graphic driver but graphic driver support for mobile computers is pretty limited and I dont think you can do much about that.
    What you can try is to download and install driver from graphic card manufacturer but you must do this on your own risk.
    Sorry friend but I dont have any other advice for you. I just think youve bought wrong notebook for such complex graphic operations. 2 GB RAM? I dont know.
    Good luck.

  • Satellite X200 with Windowa 7 became slow with JAva 6 update 17

    After installing Windows 7 on my Satellite X200 I made the upgrade of Java from update 10 to update 17. The computer became very slow when ther a Java window opened in IE8. I uninstalled update 17 and installed update 10 again at no avail. Please help!

    I agree with you and will try to get an answer on a Java forum. I tried a recovery to an earlier date but the recovery failed, probably because I had already unninstalled the original java update 10. The same happened even after I reinstalled update 10 (which, by the way, is not shown on the list of programs of the Control Pane remove programs list.

  • Wifi drivers not found - Toshiba satellite c660 PSC1LE - windows 7 64Bit

    Hi,
    I'm looking for the wifi drivers for my Toshiba satellite c660 PSC1LE laptop.
    Already tried this search: http://eu.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=EU
    and 0 resaults...
    my newly installed windows 7 home premium 64Bit doesn't identify any wifi device, and after installing a driver from a different source my computer gets stuck while trying to connect to a network.
    Do you have any idea what can I do? How to get my internet running?
    I really need some help...
    Thanks!

    thank god!
    after a weak struggling with it, I finally managed to get it to work...

    If you are having the same problem, find your laptop's specifications, find your wifi adapter, search for the drivers for it.
    sorry guys, and thanks!
    I saw there were some questions regarding the same problem but no answers.
    I hope this will help people.

  • Re: Does Satellite C660 support Windows 7 64bit?

    My Toshiba Satellite Notebook C660/01C PSC0LA-01C01H came with Windows 7 Home Premium 32-bit installed. I later upgraded to Windows 7 Professional 32-bit.
    This supports a maximum of 4 Gb RAM.
    The Celeron Dual-Core T3500 CPU supports 64-bit processing according to the Celeron and C660 specs.
    Will the other hardware and firmware -- data bus and BIOS, etc. -- support 64-bit memory addressing if I install Windows 7 Professional 64-bit. CAN I even install Win7 64-bit?
    Regards,
    Hedley

    If you want to get hardware details about your notebook, why you dont install an hardware diagnostic tool like Everest Home Edit or SANDRA Sisoft.
    By the way; as far as I know there are different C660 Satellite series on the market and there are also Win 7 64bit drivers available on the driver page.
    So tell me why an notebook manufacturer should release Win 7 64bit drivers if such system would not be compatible?
    For me it does not make any sense

    Hi there,
    you should checkout these both sites for drivers since the drivers were modified to run on mobile systems too:

    Otherwise I don´t know a accurate source for video drivers which are up-to-date.

  • Satellite C660-1FS - Windows 7 startup error

    Hello to everybody. I have this laptop with Windows 7 Home Premium (no installation disk given by purchase). Since this morning I experience the following message/problem
    Windows Error Recovery
    Windows failed to start. A recent hardware or software change might be the cause.If windows files have been damaged or configured incorrectly, startup repair can help diagnose and fix the problem. If power was interrupted during startup, chose start windows normally
    Launch Startup repair (recommended)
    Start Windows Normally
    Both options do not work. Furthermore, Windows cannot enter in Safe Mode. I live in Belgium and I don't know what to do. Shall I try with a friend's windows 7 installation disk (from Dell notebook) or I should contact Toshiba directly?
    Thanks in advance

    Check if you can recover the notebook using HDD recovery procedure as described here:
    http://aps2.toshiba-tro.de/kb0/HTD1303440001R02.htm
    If this will not work, you will have to install the OS using recover disk.
    I assume you have not created the recover disk in the past. Right?
    In such case you need to order the recover disk from here:

  • Mac with vpn tracker software running very slow

    Hello,
    I leave in Seattle and I use a Mac G5 running vpn tracker software tunneling into a Microsoft corporate network in San Jose, CA. My mac is plugged into a router and it is very very slow. I also have a PC with vpn tracker software which is running wireless and it is fast. Any ideas on what I need to do to make the Mac run faster. Could this be issues with my clients network? Should my Mac G5 be running wireless in order to get it running faster? Any advice would be appreciated.

    Having more RAM has little or diminishing affect unless you are runnning apps that need and can use it (graphics being one, such as CS5 and later).
    Many laptop owners and desktop like SSD for shorter boot (Mac always boots fast, quicker than Windows, use both).

    Backup of coure, TimeMachine and maybe one other method or set is useful, then do a clean install and reload the OS and let it do all the updates.
    Most of the time after a lot of digging around and questions and answers, it gets down to "Did you install xyz" and a list of 3rd party programs, drivers and apps that you added that aren't part of the core OS or from Apple. Whether Norton (notorious) or some "cleaner" program or even something you need but which may not be compatible with or needed with OS X and Mountain Lion.
    You can also set aside 100GB and run Windows natively as well as a guest VM OS.
    Along with monitoring RAM, disk activity, I've seen RAM DIMMs that were 'loose' or not fully seated - even though Lion OS ran well the second that they tried to install Windows 7 on their MacBook Pro it had errors and could not complete. They had upgraded the RAM on their own. Just odd that OS X was that immune and insensitive.

  • Powerful System With Bottleneck: PPro CS6 Preview Very Slow.

    Hello there!
    I'm a YouTube MotoVlogger filming with 3 GoPro cameras in 1080p, which I stack up in Premiere CS6 to get different angles. I also sometimes make use of a green-screen for other fun things and will export this as an uncompressed TGA-sequence from After Effects, with alpha of course.
    I've been having really bad problems trying to preview my project in Premiere CS6, and despite my system being fairly-powerful, I know there's a major bottleneck somewhere—probably with my HD setup with respect to editing. I basically can't preview a TGA sequence (which is repeated 3 times at different scales) without rendering first.
    Initially, I suspected my video card since it was a GTX550Ti and wasn't fully-supported, but only has 192 CUDA cores. I went and got a GTX 680 with 1536 CUDA cores but noticed no real improvement. I am also not getting any kind of yellow pre-render indicator in Premiere. It's just all red and doesn't preview well at all.
    My system specs:
    Dual XEON Hexacore, 24-cores total
    48GB RAM DDR3
    SSD Boot drive (OS)
    Main Drive: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive (Premiere installed here).
    3TB Backup drive (USB 3)
    NVIDIA GTX 680 Video
    Of course, had I known about this RAID stuff or that I would get heavy into editing, I would have gotten the system built with RAID 0, but I don't have it and I have a lot of stuff installed, from 3D Graphics to Audio software, vinyl cutting, etc.
    So, am I correct in my guess that my HD I/O is way too slow? I need to try setting the scratch disk to the SSD, but there's only 24GB available. Total storage is about 128GB or something like that.
    I was thinking of going with a USB3 External Raid 0 setup. Would this be a good fix for my Project files?
    Any help is appreciated.
    On an unrelated note, is it just me or is anyone else having issues using FireFox with this forum? My cursor keeps jumping back to a prior line of text! Super annoying.
    Thanks!

    I have read other messages that indicate that PPro does not LIKE to be installed to anything other than the boot drive... and it sometimes (often?) does not work properly if installed to anything other than the boot drive
    Since you have PPro installed to the same drive that you are using for video files, you are overloading your data transfer capability... in effect, you are using only one drive (see below)
    Trying to use only ONE Hard Drive for Video Editing
    You are a music conductor, with a baton that you use to point to various parts of the
    orchestra... this is like Windows pointing to various parts of the hard drive to do
    Windows housekeeping or to load program segments for various functions
    Now, at the same time and with the same hand... while still using the baton to conduct
    the orchestra... pick up a bow and play a fiddle... this would be doing something with
    your video file at the same time as all the other work
    You as a person cannot do both at the same time with the same hand
    A computer is a LITTLE better, in that it can switch from one kind of task to another
    very quickly... but not quickly enough for EASY video editing
    You need AT LEAST two hard drives (separate drives, never a partition
    http://forums.adobe.com/thread/650708 for more) with Windows (or Mac OS) and software
    on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down
    by trying to do everything
    Partition = Crash http://forums.adobe.com/thread/957286
    My 3 hard drives for video editing are configured as...
    1 - 320Gig Boot for Win7 64bit Pro and ALL program installs (2)
    2 - 320Gig data for Win7 paging swap file and video project files
    When I create a project on #2 drive, the various work files follow,
    so my boot drive is not used for the media cache folders and files
    3 - 1Terabyte data for all video files... input & output files (1)
    (1) for faster input/output if you have 4 drives
    - use drive 3 for all source files
    - use drive 4 for all output files
    (2) only 70Gig used, for Win7 & CS5 MC & MS Office & other smaller programs
    Search Microsoft to find out how to redirect your Windows paging swap file
