  • what's POST code 18 / can I run an ASRock P55 Pro + Core i3 530?

    - by Michael Borgwardt
    When I switch my newly built PC on, the fans start up, but I get nothing on the monitor, and the POST display on the motherboard runs quickly through various codes and then stops at code 18, which does not appear in the manual (the list there seems identical to this one). This lasts about 10 seconds, after which the machine shuts down. After a pause (also about 10 seconds) it starts up again, and this repeats until I cut the power. Interestingly, when I push the reset button, it stops at POST code 16 (which is also not listed in the manual). Does anyone have information about the meaning of those codes? Motherboard: ASRock P55 Pro CPU: Intel Core i3 530 Graphics Card: Sapphire HHD 5750 Does anyone have experience with that Motherboard/CPU combination? It says on the packaging and in the manual that it's only compatible with Core i5 and i7 (no mention of i3), but on the maker's product page, the i3 is listed as compatible as well.

  • Can DVI look different?

    - by queueoverflow
    I have a desktop with an nVidia GT 9500 which has two DVI slots. I have a 24" TN-Panel TFT on that and it looks pretty good. Then I hooked it onto the DisplayPort of my ThinkPad with the Intel HD 3000 card with an DP-DVI adapter and I think that the fonts look even clearer. Both computers run Kubuntu 12.04, although the ThinkPad is freshly set up, while the desktop is migrated from the previous release. Is this a hardware thing or is it just some setting in the anti-aliasing or sub-pixel-hinting?

  • Why is the Objective-C Boolean data type defined as a signed char?

    - by EddieCatflap
    Something that has piqued my interest is Objective-C's BOOL type definition. Why is it defined as a signed char (which could cause unexpected behaviour if a value greater than 1 byte in length is assigned to it) rather than as an int, as C does (much less margin for error: a zero value is false, a non-zero value is true)? The only reason I can think of is the Objective-C designers micro-optimising storage because the char will use less memory than the int. Please can someone enlighten me?

  • OutOfMemoryError loading Bitmap via DefaultHttpClient

    - by Goddchen
    i have a simple problem: Although i'm using sampleSize properly, my code doesn't even reach the BitmapFactorycode, since DefaultHttpClient is already throwing the exception. Here is my code: DefaultHttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(mSongInfo.imageLarge); HttpResponse response = client.execute(request); int sampleSize = 1; while (response.getEntity().getContentLength() / sampleSize / sampleSize > 100 * 1024) { sampleSize *= 2; } BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = sampleSize; final Bitmap bitmap = BitmapFactory.decodeStream(response .getEntity().getContent(), null, options); And here is the exception: 0 java.lang.OutOfMemoryError: (Heap Size=11463KB, Allocated=7623KB, Bitmap Size=9382KB) 1 at org.apache.http.util.ByteArrayBuffer.<init>(ByteArrayBuffer.java:53) 2 at org.apache.http.impl.io.AbstractSessionInputBuffer.init(AbstractSessionInputBuffer.java:82) 3 at org.apache.http.impl.io.SocketInputBuffer.<init>(SocketInputBuffer.java:98) 4 at org.apache.http.impl.SocketHttpClientConnection.createSessionInputBuffer(SocketHttpClientConnection.java:83) 5 at org.apache.http.impl.conn.DefaultClientConnection.createSessionInputBuffer(DefaultClientConnection.java:170) 6 at org.apache.http.impl.SocketHttpClientConnection.bind(SocketHttpClientConnection.java:106) 7 at org.apache.http.impl.conn.DefaultClientConnection.openCompleted(DefaultClientConnection.java:129) 8 at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:173) 9 at org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:164) 10 at org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:119) 11 at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:359) 12 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:555) 13 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) 14 at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) 15 at de.goddchen.android.easysongfinder.fragments.SongFragment$1.run(SongFragment.java:79) 16 at java.lang.Thread.run(Thread.java:1027) As you can see, the code doesn't even reach the part where i check the size (Content-Length) of the image and calculate a proper sample size. I wasn't aware that simply calling DefaultHttpClient.execute(...) will already load the complete content into the memory. Am i doing something wrong? What is the right way to first retrieve the content length and then start reading the content from an InputStream? EDIT To avoid common answers that show how to load images from a URL: i already know how to do that, i have also posted the code above, so why do you keep referencing tutorials on that? I explicitly was very clear about the problem: Why is HttpClient.execute(...)already fetching the whole content and storing it in memory instead of providing a proper ÌnputStreamto me? Please don't post any beginner tutorials on how to load aBitmap`from a URL...

  • How to find all photos taken in April - any April?

    - by Mawg
    I have 100+ gB of photos going back 25 years. They are arranged in a directory tree by category, with nested sub-directories. How can I make a search for all photos taken in a given month, say April, in any of those directories? I don't think that a Windows search will work as that will probably be the file creation data, which could be a month or two later wen I finally more the files from SD card to PC. Perhaps searching the EXIF data? Is there a free program which can do that?

  • Is there a way to adjust colors of a specific window?

    - by Synetech
    Is there a (Windows) program or something that will allow the user to adjust the brightness/contrast/gamma of a specific window rather than the whole screen? As a use-case scenario, imagine having a web-page showing on one half of the screen, and another program taking up the rest of the screen. This other program uses the default Windows colors (e.g., white background), so it may be glaringly bright. Alternately, the web-page may be too dark to see. Adjusting the monitor or video-card settings would affect everything which will be no good. Adjusting the default Windows colors is, at best, inconvenient. Instead, there needs to be a way to set the colors of one of the windows to equalize the whole screen.

  • Deploying virtual machines - Windows Guest/Linux Host or vice versa?

    - by samoz
    I'm looking to deploy several virtual machines for users. They need access to both Windows and Linux. They also need to use the computers graphics card (for Photoshop, modeling, etc) under Windows. My question is, will an Ubuntu host/Windows guest or a Windows host/Ubuntu guest be faster? I'm somewhat worried about Windows getting a cluttered registry and slow, but on the otherhand, a Windows host would have direct access to hardware (Unless I'm just unaware of how to grant hardware access to a guest). Does the choice of software (VMware or VirtualBox) effect the choice?

  • Computer powers off then tries to start up but resets repeatedly.

    - by Sam Holder
    My machine has started shutting itself off after a few minutes on, everything goes off. A few seconds (3-5) after everything has stopped the lights come back on, the cpu fan and gfx card come on again. They spin for a second, then everything goes off again. A few seconds later same things happens again, light come back on, fans spin for a few seconds then go off. This repeats seemingly forever. If I leave it for a while I can power the machine back on for a while and it will boot again. It will then stay on for a little while again before power off. Rinse and repeat. Is this likely to be power supply or something else? The machine has been up and running for a couple of years before this.

  • Unauthorized computer use via keyboard or remote access?

    - by brydaverambo
    I’m suspecting my computer is being used when I’m not at home. This is happening either physically or remotely. My wireless switch is off. Is there any way possible to detect and/or monitor activity without purchasing software? My settings are being changed as well as passwords (Bios PW was changed and I cannot access Bios settings). I connect via the network cable. Is it possible for someone (in range) to connect to my laptop even if the wireless switch is off? This is a Dell Inspiron 1720 with the WLAN 1395 card. Here’s the kicker. When I try to download freeware for monitoring activity, I am not allowed to do this! ????

  • I need a 3ds loader for opengl

    - by Shaza
    Hey, I have an opengl project with C++, and I need to load like 10 3ds objects in my scene with their texture on, but unfortunatly the loader I'm using now is causing memory leakage, I knew that when my scene freezed after running the project by one min, so can you suggest a 3ds loader which can be very effective in loading a big number of 3ds objects??

  • Win XP cannot connect (or see) my wifi network, but can see others

    - by Jorre
    since yesterday I have a strange wifi problem with my pc. I have a wireless linksys router setup that worked fine for many months, now since yesterday my pc won't connect to the wifi signal anymore. The strange thing is, my macbook pro still connects fine. SSID is broadcasting, but my windows XP doens't see it, I have all signal modes set to "auto". Windows XP sees all my neighbours wifi networks, so the wifi card isn't broken or anything. Any idea what can be wrong here?

  • Things in .NET Framework 4 that every programmer should know

    - by Faruz
    I recently moved to Visual Studio 2010 and upgraded my website to work with .NET Framework 4. (From VS 2008 - Framework 3.5) What are things I need to know to improve site speed, readability or memory use? For example, I found out that when I use AJAX ScriptManager, one of it's new properties is EnableCDN which enables me to load AJAX .js files from Microsoft CDN.

  • SQL Server 2008 - Query takes forever to finish even though work is actually done

    - by Brian
    Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA

  • DOM Storage and locks

    - by user535759
    Since DOM storage and its equivalencies persist in between tabs and windows, I've thought about using it for message passing. The problem is that fetch and store are different operations, and therefore not atomic. I have models that rely on UUID generation, conflict resolutions, and beaconing to do the small subset of what I need to do, but my real question is this: Since the local storage is a shared memory resource, what are the locking mechanisms available for mutual access?

  • Windows 7 - all usb devices go to sleep im idle mode

    - by dvdx
    A strange thing happened after a few updates to the system: Intel rapid storage SSD firmware update Intel Ethernet adapter update GPU Intel update When the computer turns off the screen (after 5 min), an unknown time later, all the USB devices stop working. Sound card Mouse Keybord etc. I can't turn them back on, so I can't wake up the screen or do anything except turn the computer off and back on. I checked my power save profile and all is OK there. I changed in the Device Manager, the Allow USB to sleep in all the hubs. How can I fix this??

  • How to automatically monitor and limit resource of process on Windows

    - by Nat
    On Linux, normally I use ptrace function to trace all syscall, and kill the process if the it tries to do anything harmful to my machine, such as system("shutdown -s -t 00") or so. Is there a way for me to do this on Windows? EDIT: I want to write Sandbox program to limit time and memory usage of its child that can work on both Windows and Linux, and now it can only run on Linux via ptrace

  • My Router is fast when i reset it but slows down seconds later

    - by hglocke
    I have a Belkin N wireless router which until recently worked perfectly fine. Now i have to reset the router every few minutes, otherwise it slows down to a crawl. What can I do? I have tried turning the routers firewall off, but it does not make any difference. As far as I'm aware there have been no recent firmware updates. EDIT: The other devices on my network (laptop and iphone) do not have this problem. I connect to the router using a TP-Link wireless network card and I have already tried uninstalling and installing the driver. Hopefully this will narrow down the problem significantly.

  • Can I run Ubuntu directly under Windows 8?

    - by huahsin68
    Text below is extract from the article, Windows 8 Tip: Virtualize with Hyper-V. Better still, Windows Virtual PC offered a feature called XP Mode, free for users of Windows 7 Professional, Enterprise, and Ultimate, which included a full working copy of Windows XP with Service Pack 3. But the big deal here is that as you installed applications in the virtual copy of XP, they would be made available through Windows 7’s Start Menu. And you could run these applications, side-by-side, with Windows 7 applications on the Windows 7 desktop. It was a seamless, integrated experience, ideal for those one-off application compatibility issues. I was thinking to install VirtualBox in Windows 8 and then run Ubuntu as guess OS. Since Hyper-V is a Type-0 hipervisor, may I know does this bring the same benefit if I have Ubuntu Linux install as a virtual guess OS? Meaning, if I turning the Ubuntu on (the guess OS), does the Ubuntu still able to access the hardware information like nVidia display card or processor information? I'm just curious to know can this be done?

  • DVI monitor detected only on computer startup

    - by kamil
    I've recently connected a new monitor, LG M2252D-PZ, to a rather outdated computer with Windows XP and Radeon 9600. XP has SP3 installed, video drivers are the latest version back from the times the video card was still supported. My problem is that the monitor works fine only as long as I don't turn it off or switch it to a different input. When I turn it back on, it says "no signal". The key to the problem must be the DVI port, to which the new monitor is connected. The previous monitor was connected to the VGA output, and I've tested that the new one also works fine when connected to the analogue port. Apparently, the computer tests for the presence of a monitor on the DVI port only on startup. The question is, how do I change this?

  • How to get headphones and speakers working at the same time?

    - by Borek
    I have a Gigabyte P55-UD3 motherboard which comes with a Realtek sound card and audio header for the front panel. My headset is permanently connected to the front panel (mic in, headphones in) and I also have speakers connected at the rear of the computer. What I want to achieve is that both the headphones and the speakers work at the same time. On my old PC with Realtek, I was able to do this by clicking "Device advanced settings" in the Realtek HD Audio Manager and then clicking "Make front and rear output devices playback two different audio streams simultaneously" and then doing some reassigning of front/rear settings in the Realtek Audio Manager (can't remember the details). But that doesn't seem to be working now - either the speakers play sounds or the headphones, not both at the same time. To pose the question differently, Windows plays the sounds on the "default device". I'd like to make both headphones and the speakers kind of like the default devices.
