X-fi Hardware causing Low-level system Crash? Black Screen+Repeating Sou

This a problem that has persisted in my computer through three motherboards, two processors, a graphics card, two Operating systems, and a RAM overhaul. I am currently running:
Vista Home Premium 32 bit
2x SATA 250 gig
Gigabyte 965P-DS3 Motherboard
Core 2 DUO 6600
2x 2 Gig RAM
BFG Geforce 7900 GT 52 Ram
Creative X-fi Fatality Extreme Gamer
The Problem:
Typically while playing a game, after -3 hours, the screen will go black, and the speakers will emit loud popping/crackling. This happens without warning. Sometimes (Rarely) the computer will immediately reboot. Usually, it just locks up. I used to think this was a graphics card issue, However--
Today, it happened while I was just doing some desktop publishing work, while listening to iTunes. I'd had iTunes up for about 5 hours, playing music in the background. Without warning, the system crashed to black screen+popping.
Because this happened when I was at my desktop, and not in a game, I think it is not related to graphics. Any ideas?
Steps I've taken so far:
Replaced Power Supply
Disabled onboard motherboard sound,
Updated BIOS/Flashed CMOS,
Updated Chipset drivers
Uninstalled/Reinstalled newest Sound card Drivers
Uninstalled/Reinstalled newest graphics card Drivers.
Purchased additional case fans.
The previous system, which encountered the same problem, was an Evga board running XP, with different RAM.
At this point, I've run out of potential solutions. I've talked to a friend of mine, and he says that if none of that helps, it may be a low level issue either associated with heat, or a bad X-fi card. Any additional thoughts would be appreciated.Message Edited by Miyth on 0-04-20070:39 PM

  • Why does Final Cut cause a hard system crash after upgrading computer's memory?

    2x2.8 gHz Quad-Core Intel Xeon MacPro that orginally came with 2gBs of memory. We upgraded to 4gBs of memory by adding 2 1gB ram chips. Ever since, Final Cut Pro has been causing hard system crashes. Does anybody have an idea why this is happening?

    Installing memory is very specific
    the correct type of DIMMs must be installed in the correct slots dependant on the type of processor fitted
    install exactly as per the Mac Pro guidelines here:
    Mac Pro Memory DIMM Instalation
    you will have to reload the web page a few times after the page warning to down load correctly (command R)
    if it is per the instructions and your having trouble, the DIMMs are most likely faulty

  • System crash (blue screen) during CD burn

    Hello All,
    I need your advise due to serious problem with my PC. Per technical specification located in the following site CPU support: the motherboard supports 133/266 MHz FSB and Ratio 12.5.
    Unfortunately, I found out that my recently purchased computer doesn’t work at such frequency(FSB=133, Ratio = 12.5), namely, all operation related to the DVD-ROM (Pioneer DVD-120) or Samsung CD-R/RW eventually caused system crash. I tryed to reinstall the OS, however it has not solved the problem. Only frequency decreasing allows to avoid the crash(blue screen of death). The proper volatages and temperature value are as follows: Vcore = 1.74V. PS_3v = 3.25V, PS_5v = 4.95V, PS_12v = 12.24V,  Tcpu = 48C, Tsys = 33C.
    Please advise,
    Thanks, Raz Noam
    Here is my configuration:
    Athlon XP 2000+
    KT4V MS6712 motherboard
    256 Mb  DDR 333 Smasung
    40 Gb IDE master on IDE1
    60 Gb IDE slave on IDE1
    Samsung SW 248F master
    Pioneer DVD-120 slave
    Windows XP Home Edition

    System crash that I have experienced occurs only during CD Burner or DVD activities. It is very random, however I have notice that when I am burning CD (test mode only) the system crash occurs quite often. I attribute it to the fact that this mode is perhaps harder than only play. However, system crash occurs also during play mode. The crash is actualy stop mode with different error core, I mean, stop 0xd1, 0x0A, 24, 77. BTW, I dissabled autoreboot option. So far it was no problem with reboot after crash. So, I suspected some problem with mainboard, however, perhaps, that PSU can impcat as well. Unfortunately, I have no experience with PC hardware, therefore I need your advice based on rich experience. What I dare to assume that the problem rather in hardware than in SW.

  • K8N neo Platinum Win XP SP2 random system crashes/Blue screen

    I have recently built a new pc with the items as listed in my signature.  Some of the compontents were new (RAM, HDD and VIdeo) and some were second hand (CPU, M/B, Keyboard and Mouse).   I found that when I install WIN XP the system seems ok.  But after I install any SP1 or SP2  which are required to run the USB2.0 my system crashes randomly and I get a windows blue screen and an auto restart.  in the last week it sometimes lasts a day or so then it crashes.  Other times it will crash within 5 minutes of start-up.  I found a forum topic about a similar problem the other day but when I went looking for it again I couldn't find that topic.  In that topic there were comments about PSU's and their ability to run the K8N Neo Platinum.  In my specs are my PSU details.  Can anyone advise if my PSU may be the problem or if there is any other problem.
    I have made a WIN XP boot disk with SP1 and I have an SP2 disk I was given by a PC shop.  If you are able to help or need further info to be able to help please let me know.

  • Imac crashes black screen

    Imac Crashes leaving black screen, need to turn off and on again to remedy.... quite sporadic in any programme - can anyone help?

    The fans may not be the cause of the problem but it's definitely related. Now I'm running the hardware monitor every time I play D3 and it always warns me that the CPU fans is spinning up shortly before the crash, which may then occur within seconds or at most 2-3 minutes when I stay in fullscreen. I can't remember experiencing a crash after I went back to windowed mode after the alarm, but I also haven't pushed it much. Also, the temperatures reported really don't look awful at all, nothing exceeds 80°C, there's no sudden surge.
    Interestingly, the computer actually keeps running after the screen goes black (but D3 is definitely out), and only when I press cmd-alt-esc does the whole system go completely down (looping sound).
    I've checked the logs and couldn't find anything really significant, then again I may not know what to look for. The only suspicious entries at more or less exactly the time of the crash (although I can't tell whether it's when D3 crashes, or the whole computer) are the following in kernel.log:
    12-07-14 2:57:48.000 PM kernel: ** Device in slot: SLOT--1 **
    12-07-14 2:57:48.000 PM kernel: ** GPU Debug Info Start **
    12-07-14 2:57:48.000 PM kernel: 0x00006740
    This is followed by 544 lines similar to the last one with various hex addresses over five seconds, although after line 436 only 0x00000000's are reported. The line just after that is at the time when I restart the computer and says
    Jul 14 15:00:36 localhost kernel[0]: PMAP: PCID enabled
    system.log doesn't report anything in this time frame, there's no crash report for D3 in CrashReporter... Is there anything else I could check?

  • Sudden video crashes/black screen flashing with MSI GTX 680 + MSI GT 640 (PhysX)

    I've been running an MSI GTX 680 Lightning + MSI GT 640 (dedicated PhysX) setup since last September with excellent results. Most of my Steam games would crash in less than 10-15 minutes before I added the 640.
    Just this week, however, I've noticed a new and different problem. While playing several different games, the monitor randomly flashes black, then the game stutters and finally my whole system crashes. I've never seen this before. The only thing that seems to correct the problem is to scale back the resolution from 2560x1600 to 1920x1200 or even 1280x800.
    The problem seems to be getting worse. Now, while doing anything on my PC, the system freezes briefly, the screen rapidly goes black, then turns back on and system unfreezes. This happens 3-5 times in a cycle then stops. The cycle repeats every few minutes and happened twice while typing this post.
    I've got the latest graphics and other component drivers installed. All diagnostics say the video cards are working properly, but these problems persist.
    Are these indications of failing video cards? Any/all suggestions appreciated.
    My system specs: MSI GTX 680 Lightning 2GB, MSI GT 640 1GB (dedicated PhysX), i5-2500K, Asus P8Z77-V, Coolermaster V8, 16GB Corsair Vengeance 1600, 4TB storage, Corsair HX1000, Dell 3008WFP, Windows 8 Pro 64-bit.

    First of all remove the GT640 so we can check if the issue is solely related to the GTX680. Then monitor temps in load and idle using Afterburner (>>How to use MSI Afterburner<<)
    If problem presists when not using the GT640 remove current drivers in safe mode using >>Driver Fusion<< and install latest MSI driver (http://www.msi.com/product/vga/N680GTX-Lightning.html#/?div=Driver&os=All). Yes, I know that driver is older than Nvidia one but it is a surely working one with the special MSI design and features.

  • ITunes with videos bad, Music & Regular! Crash, Black Screen, Tagging?

    So i have been using iTunes for ages and have been collection Music's CD's longer and i got to load them to iTunes a while ago. Music works great in iTunes but with my CD's i often got music video's included so i tried to play them and some regular videos in iTunes and got the following problems and issues (Almost all the tested video files was optimised for iProducts (All MP4 format)) :
    Can't use some of my music videos (mp4 format) in itunes but i can in Quicktime (Got black screen but good sound ). I have no idea how they coded iTunes but shouldn't they use the same codec's?.
    iTunes have a tendency to crash if i play music videos in a row. (Like to use random in a music video list, calming in the background. i know it's kind of excessive but i like it).
    Sometimes i need to play through a music video then reverse back to it to get a picture. (Sound works great tho) .
    Laggy! Sometimes the sound get out of sync with video and vice versa. (Usually the beginning.  Has a tendency to catch up but not always, sometimes a middle lane in the video freezes.)
    Can't you tag or sort video files better.? My computer sometimes crashes or get changed so i need to reinstall my media library from a backup. It would immensely help if i could ID3 tag media files the same way i can song so they automatically sort in to music video's, movies and Tv-series (media types!) without forcing me too change it in the advance tap at show more information. (This is off topic but i need this for audiobooks too (iTunes don't got my type of books so i am manually coping them from CD to MP3 format and transferring them to my iPhone))
    So i'm a trial and error person so i worked a little bit with the problems when i had the time and  when finally got somewhere and had some real questions so i created this profile and wrote this post.
    Please read the whole post before you go yelling: -Look at this!, Already Asked!, See this forum! It's your computer! I usually get to the point somewhere on this post. At the bottom of the post i have my current specs for my computer. So here comes the wall of text:
    I started with this http://support.apple.com/kb/TS1718?viewlocale=en_US and http://support.apple.com/kb/TS1717 which is what you get if you search a bit in apple's support site. Tried all the things there. Disabled Direct3D, Tried Safe Mode On (Note: These two made the performance worse not better.), Checked display colour quality (Maxed), Turned on DMA, (A slight improvement still issues.) and finally got to ReadyBoost. I have all my media on an external drive (Aha you says!) and yes i finally figured out that iTunes can't handle files of that size from a regular external (Observe i do not have ReadyBoost on my 1T drive, It says it don't have the necessary performance). So i moved my video files to my internal drive and it significantly improved in problems 2,3,4 (Not gone!), Also noticed that i need to have as short pathway as possible (smaller improvements yet again!) (None of this shows in troubleshooting, Apple needs to read my post i think.)
    I am now browsing web forums for a better suggestions on the problems and found that Apple either did not care about the problems or the members of this or other forums recommended other media player's to use for handling devices and media (MediaMonkey, doubleTwist and so on). Either as to further their own agenda or that they have giving up on iTunes as a media player for large number of media files. (Found a good media tagger, Magic MP3 Tagger, which worked wonders on some of my older albums with no or little information). So back to my problems or questions.
    What can be the trouble with a mp4 format?
    Tendency to crash, is iTunes really that unstable?
    Play through music video to see picture. Really iTunes?
    Laggy! don't know what more to say or fix. (iTunes take to long to buffer (got between 0-15 seconds delay after i come this far, better then before but not great)
    Sort video files better. (Tags). The only format i know to date that instantly recognise what media type it is, some movie format and the ringtone format m3u  (Useful to know is that you can make your own ringtones by creating a ACC with a limited play time in advanced tab (max 30 seconds)  then change the last file ending of the ACC file now created to m3u. Viola! (Don’t forget to change back to the regular playtime on the original file) your custom created ring/smstone in workable and high quality, but i digress).
    Sorry for the long read but i wanted to be as thorough as possible and please forgive any grammar and spelling problems. English is not my native tongue and the spelling checker did not work in my laptop (browser) on this website
    Currently using (The one with iTunes and the external hard drive) (But have had two different computers before with same problem, 1 PC & 1 Mac):

    This problem cropped up for me yesterday. I had just copied a new video to my iTunes library and was testing that it worked properly, but while the sound was playing, the screen was black.
    Pausing/pressing the Play button resolves the issue, until I select a new video/movie to play, when I have to do it again.
    I'm running MacOS X 10.6.6 and iTunes 10.1.1 (4). I tried reinstalling iTunes, with no luck. I also tried the old mainstay of replacing the Preferences file, but that also didn't help.
    There is ONE new wrinkle to this situation. Yesterday, I had installed a new app named AirView to stream videos over AirPlay to my iPad. This works fine, but after this, the issue cropped up, suggesting an AirPlay issue.
    I have two iMacs, so decided to try this situation on the Kitchen iMac and played a video on this other iMac just fine, video and sound. I then started up AirView on the iPad and initiated the video stream to the iPad from the Kitchen iMac. The movie played fine on the iPad. I quit AirView and went back to try the video on the Kitchen iMac, and yes, the video now failed to display until I reselected Computer from the AirPlay menu at the bottom of the screen, or used the pause/play solution, even though Computer was still selected as the default in the AirPlay menu. Doing this once seemed to be enough to resolve the issue for playing all videos on the Kitchen iMac, but not on the Office iMac.
    The only other difference between iTunes on these two iMacs is that one (the Office iMac) is running its videos from a FireWire 800 attached 2TB hard drive, while the Kitchen iMac's contents are on the internal hard drive.
    Deselecting the AirPlay option in Preferences/Devices to start videos correctly on the Office iMac is not a solution, since this iMac serves as our home server for our Apple TV.
    Since I have a practical option, however, and since this issue doesn't affect playing videos remotely using AirPlay, this is now a buggy annoyance, but no longer a problem for me.

  • 2012 13 inch MacBook Pro crashes (black screen) on Windows 7

    Hi, I am running Windows 7 (bootcamp obviously) and out of the blue my screen went black, my only option was to make a hard reset. I can then run Windows on Safe Mode, and I found out that if I turn off the graphics card (HD 4000) then Windows will run OK in "normal" mode.
    That happened a month ago, and the only thing I could think of was re-installing Windows via Bootcamp. Windows ran flawless until  a couple of days ago where the black screen appeared again and the only way I managed to get into Windows again was either on Safe Mode or in normal mode (with the graphics drivers unabled).
    Please help me, I really need to run Windows for work and this is really bothering me.

    "Don't think it's the inverter since that helps turn on the backlight on."
    Actually the inverter bumps the 5 V. ? from the logic board and bumps it up to high voltage to drive the back light.
    https://www.ifixit.com/Answers/View/51132/MacBook+inverter+board...how+to+test
    Checks you could try would be to check the input voltage to the inverter board. Check the inverter cable for shorts. These are easily seen on close inspection.  If there is a short it could have taken out the tiny fuse that's on the logic board. Or the inverter board itself could be bad. Sub board repairs would require known good replacements. I have identified that fuse but on an earlier model and repaired it after replacing the inverter cable but no tech would go that far.

  • What is the technical 'cause' of the infamous iMac black screen problem?

    Can anybody shed some light on what technical malfunction exactly causes the infamous iMac black screen problem? The common solution seems to be a logic board replacement. But what exactly is broken on the logic board? Is it the Geforce chip? Some kind of external driver circuitry? Or something completely different?

    I was referring to the many problems also described in this thread (and also in many other places):
    http://discussions.apple.com/thread.jspa?threadID=196774&tstart=0
    In specific I am referring to machines where all of this applies:
    - internal monitor stays black after power-on
    - computer boots normally
    - external display works normally
    - internal display backlight works and can be adjusted in brightness, but all pixels are black
    - PRAM reset doesn't help
    - NVRAM reset doesn't help
    - PMU reset doesn't help
    - reinstalling OS / booting from CD doesn't help
    - machines with this problem sent to repair come back with a replaced logic board
    I'm looking for more information on the technical cause of the exact problem as stated above. So I can attempt to repair my iMac

  • [Packard Bell EasyNote MX61-B] Xorg crash: black screen or segfault

    Hi everyone,
    I recently reinstalled Arch Linux after few months on Debian, and I remember I had a bug with Xorg. This bug appears known, but I can't find a solution or explication (maybe I don't search enough). Sometimes, I've a black screen for 5 seconds (approximately). I can do nothing and my computer doesn't respond. In my Xorg.0.log file, I've juste this line :
    AIGLX: Suspending AIGLX clients for VT switch
    It can happen one, two or three times in one minute, and it's very annoying. I can't reproduce that. I have no idea how, no idea of what is happening.
    But sometimes, it's more critical: same symptoms, but my Xorg session is totaly ugly. It doesn't crash, but I did as squares, rectangles of all colors.. If I kill X (with pkill X or ctrl/alt/bksp) and restart it, same result. I have to reboot my computer. In my Xorg.0.log, I've a segfault.

  • IPhone 4s turns off and crashes black screen

    HI all,
    i have a fault with my iPhone 4s  where it randomly crashes and turns off I've uninstalled recent apps to see if they were causing it but hasn't helped, it will randomly do it while using an app or browsing the net, even when recording a video I will get black marks across the screen bit like watching an old film then the whole screen freezes and just fades to black slowly,  and only way to turn phone back on is to hold lock and home screen buttons together, but this doesn't always work and I find I have to leave the phone for a few hours worse case has been overnight before it will work again..
    what could this be ?
    its really annoying!

    Hey Chriz1,
    Thanks for the question. After reviewing your post, it sounds like the iPhone will unexpectedly power off and will not turn back on. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

  • IMac crashes (black screen) while playing Diablo 3

    Hi,
    I've bought my iMac 27" i5 quad 2.7GHz 8GB in January. It's been working fine, being used mostly for some gaming and desktop apps.
    2 months ago I started playing Diablo 3, and started having problems after the first update. Basically, I can play for some time (ranging from 10 minutes to 1 hour) and after a while the computer screen just goes completely black, the last fragments of sound start to play in a loop (about .2 to .5 second) and the computer is completely unresponsive. The only course of action is to force it to shut down by pressing the power button for a few seconds. After that, it's not possible to restart the computer right away, I need to wait for a few minutes before it can start. It even happened once that it started to play the startup chime and stopped midway, shutting down all by itself.
    A similar problem also happened once or twice, when the computer was simply sleeping and it became impossible to wake it up, I had to shut it down and start it up again.
    I've explained the problem to Apple and even took my computer to the store for checkup. However, after they ran some tests they said everything was fine and didn't want to replace any component (it would have been the motherboard or the graphics card). All they could tell me was that I should reinstall the whole system (Lion, up-to-date).
    I might do that. However, tonight I tried again to play while monitoring the various thermometers and fan speeds, played in windowed mode so I could see the curves, and set up the computer to take a screenshot every second (AFAIK the monitoring app I'm using doesn't keep logs) so I could replay everything. I got my usual crash after about half an hour. What the screenshots showed is that the various temperatures raised, which probably isn't a big surprise. However, they also show that about 3 minutes before the crash the CPU fan, which had been very stable so far, started to speed up very regularly. While it didn't reach any abnormal speed, it's still weird to see how it began so suddenly and so shortly before the crash.
    As one can see from the values in the monitoring windows, the temperatures don't seem to me to be scandalous, but I may not be a good judge. Before I start reinstalling everything, I was wondering whether someone might have experienced a similar issue (couldn't find much about it on the web) or if perhaps these "symptoms" may be meaningful to someone?
    I'm grateful for any advice!

    The fans may not be the cause of the problem but it's definitely related. Now I'm running the hardware monitor every time I play D3 and it always warns me that the CPU fans is spinning up shortly before the crash, which may then occur within seconds or at most 2-3 minutes when I stay in fullscreen. I can't remember experiencing a crash after I went back to windowed mode after the alarm, but I also haven't pushed it much. Also, the temperatures reported really don't look awful at all, nothing exceeds 80°C, there's no sudden surge.
    Interestingly, the computer actually keeps running after the screen goes black (but D3 is definitely out), and only when I press cmd-alt-esc does the whole system go completely down (looping sound).
    I've checked the logs and couldn't find anything really significant, then again I may not know what to look for. The only suspicious entries at more or less exactly the time of the crash (although I can't tell whether it's when D3 crashes, or the whole computer) are the following in kernel.log:
    12-07-14 2:57:48.000 PM kernel: ** Device in slot: SLOT--1 **
    12-07-14 2:57:48.000 PM kernel: ** GPU Debug Info Start **
    12-07-14 2:57:48.000 PM kernel: 0x00006740
    This is followed by 544 lines similar to the last one with various hex addresses over five seconds, although after line 436 only 0x00000000's are reported. The line just after that is at the time when I restart the computer and says
    Jul 14 15:00:36 localhost kernel[0]: PMAP: PCID enabled
    system.log doesn't report anything in this time frame, there's no crash report for D3 in CrashReporter... Is there anything else I could check?

  • RenderToTexture with RectangleTexture causes Runtime Error and presents black screen

    Problem Description:
    Please see RTTtest.as first(https://bugbase.adobe.com/index.cfm?event=bug&id=3776210), run time error occurs on iOS devices ( I have test two devices: iPad2 and iPhone 5 )
    Error: Error #3604: Sampler 0 binds a texture that is also bound for render to texture.
    at flash.display3D::Context3D/drawTriangles()
    at RTTtest/RenderTT()[C:\RTTtest\src\RTTtest.as:274]
    at RTTtest/_OnEnterFrame()[C:\RTTtest\src\RTTtest.as:243]
    Lines between 159~189 present some of my testing results, some are correct and the others are incorrect.
    In addition, I also have test "On AIR Simulator" and nexus 7 2013, the error does not produces.
    Steps to Reproduce:
    1. directly executes the RTTtest.as on iPhone 5.
    will see the error ( on debug mode )
    2. Commenting line:169-170, and un-comment line:172-178 does not produce error.
    Actual Result:
    if ignoring the error, the render texture presents black, therefore the screen presents black.
    Expected Result:
    The testing program draws two triangles, the one is blue, and the other is red.

  • Iphone 4 crashed - black screen + constant vibrating

    HI there
    Can anyone help me with a serious iphone crash please?
    The phone showed yellow triangle saying something like 'device can not be charged with this accessory' (I wasn't trying to charge it to anything at the time), then it went fuzzy, then black and started vibrating constantly.
    I tried to reboot it via pushing the on/off and home buttons simultaneously. I tried to plus it into my laptop but itunes doesn't recognise it.
    I am in an airport on my way to Lima!
    Thanks

    Here are Apple Steps: http://support.apple.com/kb/HT1808
    You can try a DFU Mode Restore:
    Open iTunes on Computer, connect iPhone to Computer with USB Cable, hold both Home and Power buttons for exactly 10 seconds, release the Power button, keep holding the Home Button until iTunes says it has detected an iPhone in Recovery Mode, usually about 20 seconds longer. If the iPhone Screen is Black, Blank this is DFU Mode, Restore the iPhone Firmware. If something is on the screen this is not DFU Mode. Keep trying to get DFU Mode, which is sometimes difficult even for experienced users. DFU Mode = iTunes says Recovery Mode and iPhone Screen is black, blank.
    If your iPhone Restore results with an Error, write down the Error Number so you can look up the cause and the fix.
