  • System won't boot: Gigabyte HD 7790 1GB OC GPU issue or Corsair VS550 PSU issue?

    - by MGOwen
    Installed a new GPU, and PC won't boot. Turn it on and: No monitor signal at all (tried HDMI and VGA via DVI, on 2 working monitors). CPU and GPU fans DO spin, but No system beeps, no sounds from drives (they might make a small noise in the first 1 second or so, but there's definitely no OS loading or anything like that) If hit "power off" button it turns off immediately (no holding down for 3 seconds like usual) If I put my old HD 5670 GPU back in, everything works fine. But (plot twist!) card is not totally dead. My friend put it in his PC, and it works fine (he even played a game for 15 minutes, no issues). He has a Corsair TX850 850W and a Gigabyte MB. So my main theory is: the GPU isn't getting enough power from the PSU. But is it: Bad PSU? Seems unlikely, since it works fine with the other GPU. Also, the PSU Is brand new and 550W (single 42A/504W 12V rail). Overkill for this GPU. Corsair is a decent brand, but maybe just mine is faulty? Bad GPU? Could it be drawing more power than it should be, somehow, or something? Supposedly HD 7790 needs only 21A/75W on the 12v rail, though this one is factory overclocked a bit... but should that triple the power requirement? Something else? Could there be a motherboard incompatibility somehow? Both MB and GPU are less than a year old and PCI Express 3.0 x16. Things I've tried: Re-seating the video card Testing PC with old GPU (works fine, same PCIe slot). Checked AMD's stated amp/watt requirements of a 7790 and my PSU (see above). My PSU can output twice the amps (single rail) and 5x the Wattage a 7790 needs. Here are the full specs: Gigabyte HD 7790 1GB OC GPU Corsair VS550 550W PSU 4GB RAM AsRock H61M U3S3 motherboard i3-2100 500GB SATA HDD (2007-ish) blu-ray drive (new) PCI 802.11g card Edit: Motherboard BIOS Update seems to have fixed it. (If anyone has same problem and it doesn't work, comment here).

  • Is PCI Express x4 faster or slower than a standard PCI slot for graphic cards?

    - by Stephen R
    I am looking at potential motherboards for a computer I want to build and ran into this conundrum. The motherboard has two PCI Express slots that allow for 16 channel cards to fit in them. The catch is only one of them operates at 16 channels, the other operates only 4 channels. My question is, would it be faster to buy a PCI Express graphic card and install it in the 4 channel PCI Express slot? Or would it be better to buy a standard PCI graphic card and install it in one of the available PCI slots?

  • Sound leaks from speaker even when headphones are inserted

    - by instantsetsuna
    I've a Dell Optiplex 960 (which I presume has a speaker inside the tower). This speaker is normally in use whenever I play music (lets call this "tower speaker"), and when I insert my headphones in the 3.5mm jack (of the tower), the tower speaker stops and the music is played through the headphones (an obvious thing to happen). But sometimes, the tower speaker starts playing the music even when the headphones are inserted! So, the music is played through both of them! This gets quite embarrassing. So, my question is - Is there a way to turn off this "tower speaker"? EDIT : I'm using Windows XP

  • Full computer freeze with audio stuttering after playing games for a period of time

    - by Wes
    I've been having a problem with my computer freezing completely when playing games like LA Noire or SW:TOR (yay early access!). Basically, what happens is I will play for around an hour or so (depending on the game) and when the freeze happens, the entire computer locks up and any audio that was being played glitches out and stutters broken-record style (only much shorter. Very techno). I think it might be heat related and thought it might be my video card overheating, so I have been setting my video card (Nvidia Geforce 260GTX 216-core) fan to highest setting, but that has little to no effect. Now I'm beginning to think it's either my FSB or CPU overheating. Can anyone provide some insight or similar experiences? I'm really at a loss and don't wanna damage my rig beyond repair.

  • Building my own computer

    - by There is nothing we can do
    I'm planning to build my own computer. I do not have enough cash to buy all components I need in one go. I want to ask, if I buy motherboard which is compatible with i7 processor (any) and compatible with graphic card Nvidia gtx 780, does it mean that this mother board will be compatible with processors (from intel) which will be released next year? Same for graphic cards? The point is that I'd like to avoid situation where I buy motherboard let's say now, and in couple of months there will be new graphic card/processor which will not be compatible with my mother board? Or maybe shall I start completely somewhere else?

  • Multi-monitor resolution and position settings lost after reboot

    - by SoftDeveloper
    I've had two 1280x1024 monitors running for years on an nVidia 8800GT card with no problems. I've now replaced one monitor with a new 2560x1440 one. The card seems to support both fine, however every time I reboot the resolutions and monitor positions revert to the old settings. I've tried upgrading, downgrading, stripping out and reinstalling many versions of the nvidia drivers to no avail. Logging in as another user doesn't help - same problem. Booting into another another OS (Win7 64) works OK, so it is just this OS installation. During boot up everything looks fine (ie native 2450x1440 res) until the nVidia control panel or something is loaded which flips it back into the old mode. I have no old saved nvidia profiles. I can't find anything in the registry relating to these old settings. Its driving me crazy having to set resolutions and realign monitors on every reboot! Can anybody help?

  • Windows 7 sound control is not flexible.

    - by jon
    I would like to be able to listen to music on both of two audio output devices, but Windows 7 seems to only allow me to select one or the other as the Default device. When device A is the Default device, device B is muted; and vice versa. This seems to be stunningly inflexible. Since Windows 7 is unable to do this, can anyone recommend any add-on software that would control the hardware more flexibly and thoughtfully?

  • Is GPU active when there are not any monitors?

    - by Mixer
    Does GPU render anything when there is no monitor plugged in? Today I turned my old PC into some kind of a "server" which means that I want it running 24/7. I don't need any display (I will operate through ssh) so when everything was set up I removed my monitor. After a hour I checked my graphic card's cooling system and it was still hot. My graphic card is GeForce 8600 (with DVI connector), OS is Debian Linux. What is the best solution in this situation (standalone server) if GPU is active and I don't want it to waste power?

  • Multiple EyeFinity Display groups

    - by Shinrai
    Is it possible with an EyeFinity enabled card to make multiple display groups at once? I was playing with a FirePro 2460 and while a 4x1 or 2x2 display group works quite nicely, if I make a 2x1 display group and then select one of the other displays to try to make a second 2x1 display group, it disables the first one. Is there any way to circumvent this behavior and set up two separate spans on the same card? Additionally, can you set up distinct display groups if they're on different cards? I will have the opportunity to test several of these cards in one machine very shortly, but I'm curious if anyone has any experience. EDIT: I can confirm that you can make multiple spans on multiple cards (as long as they don't cross cards, obviously) (If the answers are different for FirePro/FireMV cards and Radeon cards, that is helpful and relevant knowledge - I doubt it, though.)

  • Android:Playing bigger size audio wav sound file produces crash

    - by user187532
    Hi Android experts, I am trying to play the bigger size audio wav file(which is 20 mb) using the following code(AudioTrack) on my Android 1.6 HTC device which basically has less memory. But i found device crash as soon as it executes reading, writing and play. But the same code works fine and plays the lesser size audio wav files(10kb, 20 kb files etc) very well. P.S: I should play PCM(.wav) buffer sound, the reason behind why i use AudioTrack here. Though my device has lesser memory, how would i read bigger audio files bytes by bytes and play the sound to avoid crashing due to memory constraints. private void AudioTrackPlayPCM() throws IOException { String filePath = "/sdcard/myWav.wav"; // 8 kb file byte[] byteData = null; File file = null; file = new File(filePath); byteData = new byte[(int) file.length()]; FileInputStream in = null; try { in = new FileInputStream( file ); in.read( byteData ); in.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } int intSize = android.media.AudioTrack.getMinBufferSize(8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT); AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 8000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT, intSize, AudioTrack.MODE_STREAM); at.play(); at.write(byteData, 0, byteData.length); at.stop(); at.release(); } Could someone guide me please to play the AudioTrack code for bigger size wav files?

But under XP the logic contained within FireAttackProc gets executed but none of the sound clips play. Is there a quick solution to this so the sound will play under XP? I ask for a quick solution because i am happy being able to execute fully in Vista/Win7 but would be great if there was a quick solution so it would be XP compitable also. Thank you.

  • Playing Multiple Sounds at Once in Qt

    - by Ben
    I'm trying to play background music along with sound effects using Qt. However, I can't get more than one sound to play at once. For example: QSound::play("Music.wav"); QSound::play("Effect.wav"); When this code is run (on Windows), you can hear Music.wav just start to play, but then it stops and Effect.wav plays. Is there any way to get the two sounds to play at once?

  • Which audio playback technology do I need for this?

    - by mystify
    I have trouble choosing the right audio playback technology. There's a ton of technologies to use on the iPhone, it's so confusing. What I need to do is this: start playing short sounds ranging between 0.1 and 2 seconds high quality playback, no crackle (I heard some of the iPhone audio playback technologies do a crackle sound on start or end, which is bad!) ability to start playback of a sound, while there's already another one playing right now (two, three or more sounds at the same time) What would you suggest here, and why? Thanks :-)

  • How to use a separate class to validate credit card numbers in C#

    I have set up a class to validate credit card numbers. The credit card type and number are selected on a form in a separate class. I'm trying to figure out how to get the credit card type and number that are selected in the other class (frmPayment) in to my credit card class algorithm: public enum CardType { MasterCard, Visa, AmericanExpress } public sealed class CardValidator { public static string SelectedCardType { get; private set; } public static string CardNumber { get; private set; } private CardValidator(string selectedCardType, string cardNumber) { SelectedCardType = selectedCardType; CardNumber = cardNumber; } public static bool Validate(CardType cardType, string cardNumber) { byte[] number = new byte[16]; int length = 0; for (int i = 0; i < cardNumber.Length; i++) { if (char.IsDigit(cardNumber, i)) { if (length == 16) return false; number[length++] = byte.Parse(cardNumber[i]); //not working. find different way to parse } } switch(cardType) { case CardType.MasterCard: if(length != 16) return false; if(number[0] != 5 || number[1] == 0 || number[1] > 5) return false; break; case CardType.Visa: if(length != 16 & length != 13) return false; if(number[0] != 4) return false; break; case CardType.AmericanExpress: if(length != 15) return false; if(number[0] != 3 || (number[1] != 4 & number[1] != 7)) return false; break; } // Use Luhn Algorithm to validate int sum = 0; for(int i = length - 1; i >= 0; i--) { if(i % 2 == length % 2) { int n = number[i] * 2; sum += (n / 10) + (n % 10); } else sum += number[i]; } return (sum % 10 == 0); } }

  • Saving file to phone in stead of SD-card

    - by Galip
    Hi guys, In my app I save an XML file to the users SD-card by doing File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/Message.xml"); But not all users have SD-cards in their phone and therefore my app is likely to crash. How must I change my File creating method in order to save the file to the phone's memory instead of the SD-card? Also, how must I change the loading of the file? (currently: new InputSource(new FileInputStream(Environment.getExternalStorageDirectory() + "/Message.xml")))
