  • Wrong Sound Blaster's PCI ID within Windows

    - by pavian
    I own Sound Blaster X-Fi Titanium, it was working with no problems under Linux or Windows 7. It's original PCI ID is 1102:000b but now I see different within MS Windows. BIOS setup: 1102:000b GNU/Linux: 1102:000b Windows 7: 1102:000d Windows 8: 1102:000d In last days I'm experimenting with IOMMU PCI passthrough in Xen and I tried to pass this device to virtual Windows 7 and 8. Here I found this problem. I don't know if this is just coincidence or reason of my problem but it's wrong even in physical system. Windows detects 1102:000d as a High Definition Audio sound device (I guess this name, I have localized Windows, but this is general name, the same was with Realtek HDA before drivers), it's playing but it's unstable (Windows speaker testing can crash that application) and I can't install Creative software. Used driver is hdaudio.sys. Booting in BIOS or UEFI mode doesn't change anything. Nor CMOS clean. Someone met the same problem.

  • Clicking or Knocking with Seagate HD

    - by Daniel A. White
    My laptop's main HD makes a clicking or knocking sound when Windows or the Bios tries to access it. I put it into a SATA dock and it sounds perfectly fine when spinning up, but after Windows tries to access it, it becomes a repetitive clicking or knocking sound. Does anyone know any tips that might help me access my data? I have most of it backed up, but I would still like to Ghost it before I send it off for repairs. I know my laptop is still under warranty.

  • DLINK WBR-1310B Wireless Router seems to hang...

    - by Ira Baxter
    I have a brand new DLINK-1310B Wireless Router (box never before opened, although I bought it the neighborhood computer junk store). I am using it at home (and in fact am using it this instant from a wireless laptop). When operative, I can ping it at 192.168.0.1, and I can log into it from the PC attached to by LAN and from the wireless PC at //192.168.0.1. In the course of the day since I've installed, it seems to have locked up 3 times. Each time the symptoms are my web browser (or other internet service) stops with a "No internet connection" error. Attempts to contact the router via 192.168.0.1 get no reaction, from either the wireless laptop or from the hardwired PC sitting next to it. It doesn't respond to pings to that address either. Rebooting fixes it. Its brand new. I've seen discussion in other questions about aging cheap electronics. Its too new to be aged. Anyboyd else seen this behavior with a DLINK-1310? Or do I just need to exchange it for another and try again? (I hate rolling dice, I bought the DLINK becuase a previous Linksys died of apparant heating problems). Remarkably, nobody talks about how much software is in a router. Is the stuff just buggy?

  • PC freezes after repeated clicking noises

    - by Péter Török
    I have an oldish PC (Athlon XP 2200, WinXP). Every time I switch it on, I hear a loud "click" first of all, and when it is shut down, again a click is the last sound I hear. Lately it started to behave erratically: it started to click loudly in the middle of a session. First only once in a while, then repeatedly for several seconds in a row, and finally it froze completely. We were not doing anything particular during these times, usually just browsing the web. This has already happened twice in a few week's time period. We typically use it only in the evenings, so when the freeze happened, I just decided it is time for the bed. When it was started up the next day, everything looked fine. Any hints on what could be the culprit? Could it be caused by an ageing heat fan, or dust that has accumulated inside the case? We are backing up all the data stored on it, and then will open the case to look inside, but I thought it would be good to get some background info first of all.

  • Windows Server 2008 R2 network adapter stops working, requires hard reboot

    - by Geoff Dalgas
    TL;DR version: Turns out this was a Windows Server 2008 R2 kernel networking bug. After siccing Microsoft support on it, we (eventually) got an unpublished kernel hotfix from Microsoft to address it. If you, too, are experiencing mysterious low-level network driver failures requiring a reboot/bluescreen cycle, you might want that hotfix (or maybe Service Pack 1 whenever it is released, too.) We have been using HAProxy along with heartbeat from the Linux-HA project. We are using two linux instances to provide a failover. Each server has with their own public IP and a single IP which is shared between the two using a virtual interface (eth1:1) at IP: 69.59.196.211 The virtual interface (eth1:1) IP 69.59.196.211 is configured as the gateway for the windows servers behind them and we use ip_forwarding to route traffic. We are experiencing an occasional network outage on one of our windows servers behind our linux gateways. HAProxy will detect the server is offline which we can verify by remoting to the failed server and attempting to ping the gateway: Pinging 69.59.196.211 with 32 bytes of data: Reply from 69.59.196.220: Destination host unreachable. Running arp -a on this failed server shows that there is no entry for the gateway address (69.59.196.211): Interface: 69.59.196.220 --- 0xa Internet Address Physical Address Type 69.59.196.161 00-26-88-63-c7-80 dynamic 69.59.196.210 00-15-5d-0a-3e-0e dynamic 69.59.196.212 00-21-5e-4d-45-c9 dynamic 69.59.196.213 00-15-5d-00-b2-0d dynamic 69.59.196.215 00-21-5e-4d-61-1a dynamic 69.59.196.217 00-21-5e-4d-2c-e8 dynamic 69.59.196.219 00-21-5e-4d-38-e5 dynamic 69.59.196.221 00-15-5d-00-b2-0d dynamic 69.59.196.222 00-15-5d-0a-3e-09 dynamic 69.59.196.223 ff-ff-ff-ff-ff-ff static 224.0.0.22 01-00-5e-00-00-16 static 224.0.0.252 01-00-5e-00-00-fc static 225.0.0.1 01-00-5e-00-00-01 static On our linux gateway instances arp -a shows: peak-colo-196-220.peak.org (69.59.196.220) at <incomplete> on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-222.peak.org (69.59.196.222) at 00:15:5d:0a:3e:09 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 Why would arp occasionally set the entry for this failed server as <incomplete>? Should we be defining our arp entries statically? I've always left arp alone since it works 99% of the time, but in this one instance it appears to be failing. Are there any additional troubleshooting steps we can take help resolve this issue? THINGS WE HAVE TRIED I added a static arp entry for testing on one of the linux gateways which still didn't help. root@haproxy2:~# arp -a peak-colo-196-215.peak.org (69.59.196.215) at 00:21:5e:4d:61:1a [ether] on eth1 peak-colo-196-221.peak.org (69.59.196.221) at 00:15:5d:00:b2:0d [ether] on eth1 stackoverflow.com (69.59.196.212) at 00:21:5e:4d:45:c9 [ether] on eth1 peak-colo-196-219.peak.org (69.59.196.219) at 00:21:5e:4d:38:e5 [ether] on eth1 peak-colo-196-209.peak.org (69.59.196.209) at 00:26:88:63:c7:80 [ether] on eth1 peak-colo-196-217.peak.org (69.59.196.217) at 00:21:5e:4d:2c:e8 [ether] on eth1 peak-colo-196-220.peak.org (69.59.196.220) at 00:21:5e:4d:30:8d [ether] PERM on eth1 root@haproxy2:~# arp -i eth1 -s 69.59.196.220 00:21:5e:4d:30:8d root@haproxy2:~# ping 69.59.196.220 PING 69.59.196.220 (69.59.196.220) 56(84) bytes of data. --- 69.59.196.220 ping statistics --- 7 packets transmitted, 0 received, 100% packet loss, time 6006ms Rebooting the windows web server solves this issue temporarily with no other changes to the network but our experience shows this issue will come back. Swapping network cards and switches I noticed the link light on the port of the switch for the failed windows server was running at 100Mb instead of 1Gb on the failed interface. I moved the cable to several other open ports and the link indicated 100Mb for each port that I tried. I also swapped the cable with the same result. I tried changing the properties of the network card in windows and the server locked up and required a hard reset after clicking apply. This windows server has two physical network interfaces so I have swapped the cables and network settings on the two interfaces to see if the problem follows the interface. If the public interface goes down again we will know that it is not an issue with the network card. (We also tried another switch we have on hand, no change) Changing network hardware driver versions We've had the same problem with the latest Broadcom driver, as well as the built-in driver that ships in Windows Server 2008 R2. Replacing network cables As a last ditch effort we remembered another change that occurred was the replacement of all of the patch cords between our servers / switch. We had purchased two sets, one green of lengths 1ft - 3ft for the private interfaces and another set of red cables for the public interfaces. We swapped out all of the public interface patch cables with a different brand and ran our servers without issue for a full week ... aaaaaand then the problem recurred. Disable checksum offload, remove TProxy We also tried disabling TCP/IP checksum offload in the driver, no change. We're now pulling out TProxy and moving to a more traditional x-forwarded-for network arrangement without any fancy IP address rewriting. We'll see if that helps. Switch Virtualization providers On the off chance this was related to Hyper-V in some way (we do host Linux VMs on it), we switched to VMWare Server. No change. Switch host model We've reached the end of our troubleshooting rope and are now formally involving Microsoft support. They recommended changing the host model: http://en.wikipedia.org/wiki/Host_model http://technet.microsoft.com/en-us/magazine/2007.09.cableguy.aspx We did that, and.. we'll see.

  • Computer turns itself on after any off mode

    - by Patrick
    Whenever I shut down my computer, or put it in sleep/hybernate, it turns on after two seconds. It doesn't post, it just powers on and then idles. To actually turn it off, I switch off the psu. The problem is now, whenever I switch the psu on and try to boot, it doesn't always turn on. It takes a good amount of flicking the psu switch on and off before the motherboard lights up. So far I've determined the things its not: its not caused by the mouse or network waking up the computer. I've been able to go into hybernate for the past year. And all "wake on X" settings in the bios are diabled. its not a scheduled task waking up the computer at a given hour, it occurs every single time its not due to an upgrade or new installation, since I haven't done either in a very long time I'm sure its a hardware issue. So I'd like to know, is my psu dead, or the motherboard? The psu is an Antec Earthwatts 600w, the motherboard is an Asus P5Q-E, both one year old.

  • Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not am not a "handsome prince"!

    - by Jim Dobbs
    Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

  • Old notebook internal display randomly not recognized

    - by jfcfar
    I have an old Acer TM4001 notebook. If the laptop is powered-off, with the lid closed, when I power it on, it generally works. Then, without touching anything, if I reboot the computer the internal display wil not work anymore. To make it working again I need to shut down the pc, close and reopen the lid and then turn it on. If I close and reopen the lid if it is not working after power the pc on, it won't work. When the screen is working, closing and opening it has no effect (the data cable seems ok). The external monitor always works as expected: If the internal display is not detected, the external will be the main (and only) display. This is not OS-related. When the screen is not working I cannot see the POST. What could be the cause for this?

  • Why my new GTX 660m's clock drops drastically after running few seconds

    - by trVoldemort
    I bought a Lenovo Y580 laptop few days ago, this model is equipped with GTX 660m graphics card. However, the game performance is unbelievably poor since it out from the box. I realized there is something wrong with this graphics card. I downloaded GPU-z, and did a simple test. And I was shocked by the fact that my GTX 660m graphics card is running at 135.0mhz core clock. (It should be 835mhz at least!) Even the integrated graphics card "Intel HD graphics 4000" can run at 650mhz. Further examining showed that in the first few seconds GTX 660m was actually running at 835mhz, however the core temperature quickly reached 90+°C and the clock (maybe) automatically drop to 135.0mhz. This is very strange. Anyone has any idea what's going on here?

  • What can I do to prevent system power downs?

    - by Joe King
    Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

  • What happens when a flash drive wears out?

    - by endolith
    Flash memory has a limited number of read/write cycles, after which it fails. What happens when it fails? Is it like a hard drive, where a failed write is silently moved to another part of the disk and that sector marked as bad and never used again, without data loss? Are there a limited number of replacement sectors? Do operating systems warn the user in some way?

  • DLINK WBR-1310B Wireless Router seems to hang...

    - by Ira Baxter
    I have a brand new DLINK-1310B Wireless Router (box never before opened, although I bought it at the neighborhood computer junk store). I am using it at home (and in fact am using it at this instant from a wireless laptop). When operative, I can ping it at 192.168.0.1, and I can log into it from the PC attached to it by LAN and from the wireless PC at //192.168.0.1. In the course of the day since I've installed, it seems to have locked up 3 times. Each time the symptoms are my web browser (or other IP service, e.g., POP3) stops with a "No internet connection" error. Attempts to contact the router via 192.168.0.1 get no reaction, from either the wireless laptop or from the hardwired PC sitting next to it. It doesn't respond to pings to that address either. Power cycling the router fixes it. I've seen discussion in other questions about aging cheap electronics. Its too new to be aged. Anybody else seen this behavior with a DLINK-1310? Or do I just need to exchange it for another and try again? (I hate rolling dice, I bought the DLINK because a previous Linksys died of apparant heating problems, how many do I have to cycle through before I get something that works and is long-term stable?). Remarkably, nobody talks about how much software is in a router. Is the stuff just buggy? EDIT: Happened again, while I was working on the wireless Vista laptop. (Seems like once an hour?) I was a little more careful this time. The wireless laptop can ping it. It can't get the login screen. I visited the LAN-connected PC (takes me a minute to walk from the laptop to the PC at the other end of the house), and attempted to visit a random web page. Surprise, that worked! And, now, after a minute walking back to the laptop, I can reconnect the wireless laptop, and get to the login page from it. Strange the time/date has been reset back to 2002. (I'll swear I set it and saved the system configuration after updating the firmware; it made me redo every other bit of reconfiguration again). Is there something funny about wireless leases expiring? The router says the leases it is handing out are good for 180 minutes, and the delay-to-inaccessible was only about an hour. The DSL connection seems to have a 10 minute lease.

  • remote desktop network failed connection

    - by tbischel
    I was trying to create a remote desktop connection from Windows XP to my Windows Vista Ultimate Addition machine at home. This normally works fine. Today after my connection was dropped, I tried to reconnect to my machine. It brings me to the normal startup screen, but when I tried to log in, it gave me the message "This network connection doesn't exist". This doesn't make much sense, as I have reached a Windows style login screen already. My connection returned later that day, but I'm curious as to what happened. Anyone see this before?

  • Power cut during Ubuntu upgrade to 10.04 - boots to command line, apt-get and dpkg do not work.

    - by Macha
    I was upgrading Ubuntu to 10.04, when a tripswitch tripped, cutting power to the computer. When it was restarted, it booted into a command line prompt. Google tells me to try: sudo dpkg --configure -a This gets me a lot of output that ends with a list of packages. I can't tell you what the output is, as piping the output to more/less does not work (still just all scrolls by and moves to next prompt), and redirecting it to a file just results in an empty file. Google also suggested: sudo apt-get install -f This also didn't work. Is a fresh install the only solution at this point?

  • Jan 2010 Microsoft update trashed my Win XP (64bit) PC

    - by Mark Pawelek
    I waited until this morning to install these 5 updates. My ancient Win XP (32 bit) PC has no problems but my Win XP 64 bit will not start. From the startup menu none of the 5 options given (e.g. safe mode, last known good configuration, etc) work. After selecting an option, the Windows Logo screen appears. About 9 seconds later a blue screen of death flashes [I can't read the error messages because it's there for about 100 ms] then it cycles through the reboot again. PS: This is a pretty cheap mobo (Ge Force) with an AMD 3 GH chip - but until today it did actually work. What should I do? Reinstall the O/S?

  • PSU died, is hard drive fried? Are other components damaged?

    - by srand
    After discovering and replacing my dead PSU, I was able to boot back into Windows. Everything seems to be working fine, however, one hard drive is not. Windows 7 says that this SATA hard drive needs to be formatted before it can work. Can the data be recovered? Also, is there a way to check the integrity of the other components of my computer or assume they will work fine?
