  • Thermal risks to other components when watercooling CPU

    - by B Sharp
    I recently ordered all the components for a new desktop system to replace my old, dying computer. I wanted to have a really quiet desktop, so I got a case rated for being quiet and opted to try a closed-system CPU water cooling kit (Antec Kuhler H2O 620) that was on sale for a very good price over the Thanksgiving weekend. Most of my components are still in transit, but I became somewhat worried when a friend mentioned that abandoning air cooling units can result in heat buildup inside the case due to heat generated by the video card and other components such as RAM, the northbridge, MOSFETs and voltage regulators radiating heat that the CPU fan would normally at least keep circulating around so it doesn't build up in localized areas. Is this a realistic problem? What other precautions should I take to remove heat from other components? Adding more case fans seems like it would get really noisy. Are there quiet alternatives?

  • Memory limiting solutions for greedy applications that can crash OS?

    - by Hooked
    I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process. Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program? At-home experiment*! Open a terminal, launch python and if you have numpy installed try this: >>> import numpy >>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)] * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

  • Choose between multiple keyboard layouts for different users in GDM3

    - by Daniel Wagner
    I am trying to set up a computer with multiple users each with different preferred keyboard layouts. The biggest sticking point right now is allowing each to log in comfortably. GDM used to offer a way to choose keyboard layout, but I can't discover how to set this up in GDM3. All the solutions I found when Googling this problem suggest changing the keyboard layout in xorg.conf, but that only sets a different single layout and still does not seem to allow me to change the layout between multiple choices. How can I allow multiple layouts when logging in?

  • What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?

    - by Forgiver
    I have an external hard drive that is connected to my computer (Windows 7 Ultimate 64 bit) via a USB port. BitLocker has been activated on the hard drive to protect the data. Yesterday I started downloading a huge data from the internet but now it failed to complete because of CRC error. I tried to repair it with chkdsk f:/r where f is the drive letter of that hard drive. There are many messages reporting "unreadable" as follows: What caused Cyclic Redundancy Check error on my BitLocker-enabled external hard drive and how to fix it?

  • How can I obtain/build a wireless volume knob for Windows?

    - by Mr Grieves
    I use my computer as a media center and simply love it. It's an older box running XP and it works better than everything else I've tried turning into a media center (Windows 7, Vista, several Linux distros, etc). The only thing I hate is having to walk to my audio amp to turn the volume up or down. I can use the Windows volume slider or any keyboard with keys to control volume. What I'd really love is to have a wireless knob which I can put anywhere when listening to music (e.g. kitchen) which controls the volume. It seems so simple yet I can't find it anywhere. Having controls for pausing and moving to next song would also be terrific. Griffin's Powermate could do the trick but I'd really want it to be wireless. Do you know of something I can buy or build myself to serve this purpose?

  • Getting around the FAT32 4GB file size limit

    - by Aesir
    I recently purchased a 32GB USB 3 stick that was formatted FAT32. I plugged it into my computer and attempted to copy a film onto it, the file was over 4GB however and it would not let me copy the file across because of the 4GB file size limit imposed by FAT32. After some googling I found that I could format my USB stick to have an exFAT format which would mean I could put files onto the stick greater than 4GB in size and the drive would work on both my Mac and my PC. The problem with this solution is that my PS3 cannot detect the USB stick when it is formatted with exFAT. I would like to know if there is a way I can have my USB stick formatted so it can have files greater than 4 GB and work on my PC, Mac and PS3.

  • Some info about SD card patitions after the use of the dd statment and some oiters doubts?

    - by AndreaNobili
    I am not very experienced using Linux and I have the following situation that cause me some doubts. I have wrote RaspBian (the RaspBerry linux distribution) on an SD card using Ubuntu dd statment: sudo dd if=2014-01-07-wheezy-raspbian.img of=/dev/sdb bs=1024 So if now I perform the fdisk -l statment I obtain that I have 2 partitions related to my SD card, that are the followins: Dispositivo Boot Start End Blocks Id System /dev/sdb1 8192 122879 57344 c W95 FAT32 (LBA) /dev/sdb2 122880 5785599 2831360 83 Linux And now the first doubt: the dd statment create on the SD card two partitions: 1) /dev/sdb1 that is a litle FAT32 partition (what it means (LBA)?) 2) /dev/sdb2 that is a larger Linux ext3 partition Ok...the doubt is: why it also create to me a FAT32 partition and not only a Linux ext3 partition? Ok...if I go into my computer resource I can see a device (related to my SD card) into the devices list that contains some RaspBian file, following a screenshot: And if I see the property of this device I obtain this: So, looking at the previous screenshot it seems to me that this is the small FAT32 partition, and now I have the followings doubts: If it is the smallest FAT32 partition, what contains? The RaspBian boot or what? Why, in the devices list, I have only the FAT32 partition and not also the Linux one (/dev/sdb2), to see it have I to mount it? how? Tnx

  • HDMI Sound for HTPC

    - by Brent Arias
    I have the (perhaps) the same problem as stated in this other HDMI sound to HTPC question. I tried the advice of clicking on the speaker in the system tray. I can see the HDMI audio device I want to use. That device claims to be functioning properly. But there is no sound, and it won't let me select it as the active audio device. When I click on the troubleshooter, it says that there are no speakers connected. I would think this is because my computer us unable to pipe sound through the video card (preventing the HDMI from carrying it), except that it truly claims that it has an HDMI sound device that is working correctly. So I'm not sure what is wrong at this point. Thoughts? My system is Windows 7 x64. In case it makes a difference, the video card I'm using is this GeForce GTX 560

  • How to get started in the development industry? [closed]

    - by Peter Fren
    My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

  • how do I find the ip address of a host on a Windows network?

    - by user13743
    There is a machine on our network called owner-pc. I want to learn its ip address. I'm not sure which computer it is, and I don't want to trundle to each station to figure it out.

  • Set up a GUI managed firewall for other machines?

    - by Azendale
    What ways are there of setting up a firewall for traffic routed for other machines whose rules can be managed by a GUI? Can GUFW do it? FireStarter? (or should that be avoided because it is supposedly no longer updated?) *By filtering, I'm mean the traffic I am setting rules up for is not destined for this computer. It is either from or to other computers on my LAN. Say, for (a simplified, hypothetical) example: I have an ethernet connection at my dorm that I have plugged into eth0. It gets an address of 192.168.1.185 and I also have 192.168.185.0/24 routed to me, so I don't have to do any NAT. I have a hub attached to my second ethernet port (eth1) with a few Windows computers and I give addresses out of my 192.168.185.0/24 block with DHCP. How can I use my Ubuntu box to block incoming connections from eth0 that are being routed to my Windows computers and let through just a few specific ports (so fellow students can't see what files my Windows boxes are sharing via SMB)?

  • How useful is PXE booting?

    - by J. T.
    Hi All, How fast is booting over PXE?. Is it conceivable to boot a linux installation? Does it take a long time? I have never really looked into it at all, but I was considering setting up a compiler farm and thought this might be interesting to try. Does one have a main computer that the PXE answers to to get its image? Can you have multiple PXE images to pick from? Thanks!

  • Cannot connect to telnet server

    - by BloodPhilia
    So, I can't use telnet to connect to any server but it works fine from a different computer. It just says it can't connect. I tried the following things: Disable firewall and AV protection. (Basically, there was no security feature left online) Telnet is set to "Trusted" in my AV protection. (Kaspersky Internet Security 2011) Using Putty to telnet, but apparently Putty's connection is also inhibited. (Says it can't connect to host) Disabling the telnet client in Control Panel and then re-enabling it. (Windows 7 Ultimate) hosts file is clean. Checked for nasties using MBAM and KIS 2011 as well as going though my HijackThis logs, nothing found. I can connect to the same machines/servers through the web browser, ping, tracert, etc. Only telnet seems to be blocked. Any other thoughts?

  • Windows diagnostic tools

    - by Tathagata
    I just joined a small computer lab which basically uses all Windows boxes and a few Windows Sever 2003. Coming from a *nix background I am missing all the nice tools that we have for diagnosis and troubleshooting. My question is what are the safe, free (not terribly concerned if it is like beer or freedom -both acceptable) tools out there that Windows system admins use for their day to day troubleshooting (network, applications, servers etc). I am aware of the tools that come with Windows (and their limited capabilites) - so my query is with what do you fill in your arsenal? (may be a list of win versions of tools that come in standard linux distros)

  • does any sync software find files that have moved paths within a folder?

    - by kpierce8
    Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any sync/compare program find that a file in one folder has moved locations within a compare folder. For instance say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.

  • How can I get my Sapphire Radeon 7850 to output in "1080p"?

    - by Fr33dan
    I have a Radeon 7850 connected to a Vizio 3D compatible TV. The TV has a function to parse and display SBS encoded content. On my old graphics card (a Radeon 5770) I just had to select the 1080p option in the catalyst control center. In this mode my TV reported the output mode as "1080p", with the new card the TV reports "1920x1080". I cannot figure out what the difference in between the 2 signals but the "1920x1080" cannot be switched into 3D mode by the TV. Weirdly, before windows starts the (in the Bios and so forth) the computer outputs in "1080p" so I know the card is capable of it. As soon as the blue login screen comes up though it changes back to the "1920x1080". I've tried everthing I can think of. Updated my drivers from 13.3b3 to 13.4, then even tried the 13.5 beta (Which I'm still on this moment). Tried all the "optimized" HD settings in catalyst, even the 720p modes show the resolution from the TV and not the "720p" (which it used to do on the old card when I had to lower the resolution of games)

  • How can I know I'm buying a heatsink that will work with my CPU?

    Recently I've been using my CPU a lot more for gaming, and as of two days ago, my computer had just been shutting off suddenly with no warning. I'm inclined to believe I need a new heatsink and cooling fan system. (Correct me if I am wrong.) Now I went around to BestBuy and Staples to purchase a new one, but both places instructed me to look online. Now I am posed with a problem. I don't know how to shop for one online because I want to make sure it will work with my unit. My CPU is a Pentium® Dual-Core CPU E2210 @ 2. 20GHz

  • No Games Installed with Windows 7 Professional

    - by Charles Didier
    Ordered a PC from HP with Windows 7 Professional 64-bit preinstalled, of course. No Win7 disc was included with computer. There are no games installed. I have tried to "activate" them through the Control Panel procedure, but each time I do it there is an error message telling me that not all components installed. And my Games folder is empty. Is there a solution? Synetech asked what I meant by "activate through Control Panel." I'm referring to the "Turn windows features on" procedure that's supposed to work for everybody. I'm sure it does for most, but it didn't for me.

  • email archive for multiple users

    Hi, I'm moving a web site from one server to another, and am realizing that I need to move the name servers for the domain as well (they are set to the current host, not to the registrar). So, knowing that email services will stop as soon as I switch the DNS, I'm scrambling to figure out how to archive and make available email data for folks that have mostly been using webmail for the past few years, and may not even have a computer on which to install a client to download the mail to. What does one do in this situation? Thanks for any help offered! Evan

  • How would one run a task sequence within a task sequence in SCCM 2012 SP1

    - by BigHomie
    A Shining Example: Inside all of my task sequences I have a group that installs driver packages conditionally based on computer model: And of course, this list does nothing but grow. The fact that it grows isn't a big deal, what is a big deal is that every time it changes I have to manually copy and paste those changes across every task sequence I have, which of course leaves huge room for human error. The same goes for other groups of tasks that are common across task sequences. Looking for a solution where I could centrally manage these tasks, be it link other task sequences to a group within another task sequence, or create a separate task sequence and link to that. I came across a solution by John Marcum (SCCM MVP) that mentioned this ability, but this was a while ago and I can't find the link to it anymore to see if it's even still being updated/maintained, but I'm looking for more of a free solution, or even using Powershell or the ConfigMgr SDK is fine with me, I'm no stranger to either.

  • Unable to FTP, any ideas?

    - by Nick
    I'm using Windows Server 2003. I have the FTP services installed, router set to DMZ, and currently Anonymous logins allowed. (I know, security risk, but there's nothing important on there and not worried at the moment) So here's the thing... I can ftp to my computer, list directory, get files etc, BUT only if I'm using the command prompt. If I try to log in using IE or any FTP client it's just timing out. I've tried: username@ipaddress ipaddress username:password@ipaddress and not able to get any of them to work. Anyone have any ideas? Thanks!!!
