• Can't install CUDA drivers for GeForce GT555M

  - by saeed

  I've just bought a new Asus n55 laptop. It has 2 graphics cards from Intel and NVIDIA. But when I try to install CUDA's developer driver for my GPU I get this error: "This graphics driver could not find compatible graphics hardware". I have downloaded both of the following files but both of them get mentioned error: Developer Drivers for WinVista and Win7 (270.81) Notebook Developer Drivers for WinVista and Win7 (275.33) How can I fix this problem? Actually how can I develop CUDA programs on my NVIDIA GPU?

• Best Server Ghost-Like Tool For Windows

  - by John Dibling

  I'm looking for advice on which tool we should use to clone servers. In the short term, we will be cloning identical hardware but in the long run we may want to create one image and replicate that on a different class of machine. For example, as new servers are released from Dell, we will want to continue to use the same image we already made. Right now our servers are Windows (Server 2008 & Server 2008 R2), but moving forward we may need Linux support as well. Ghost Solution Suite 2.5 seems to be the canonical tool. Are there alternatives? Recommendations/reviews?

• BSODs after Windows 8.1 Upgrade

  - by Techrocket9

  I just upgraded my system to Windows 8.1, and I have been getting BSODs that I did not get before the 8.1 upgrade. Though I cannot conclude that running the Android Emulator with Intel's HAXM is the cause, both crashes have occurred while the emulator was running. I get CRITICAL_STRUCTURE_CORRUPTION, the same error as this guy, except I don't have the hardware/software that he has that caused his problem. Minidumps here. Output of verifier.exe /all and then a reboot and then verifier /query: http://sdrv.ms/17CPVu9 Edit: According to software.intel.com/en-us/forums/topic/475129 (can't link due to lack of rep) it is being caused by HAXM. Will close question when I find a solution.

• Does Windows 8 Need New, Specialized Drivers?

  - by Synetech

  It seems like an obvious question, but I’m having a difficult time finding out if Windows 8, with all its changes, will require new, specialized drivers. I see that a lot of manufacturers have started releasing Windows 8-specific drivers for their hardware, but what about those that are not, will Windows XP or 7 drivers work or have they changed the driver/system/security architecture again, thus requiring new drivers? The closest thing I could find to an answer was a thread in which it was mentioned that the display driver model was again updated, thus requiring new display drivers, but not much else (e.g., audio cards, printers, chipsets, etc.)

• Strange Intermittent Background Sound in Windows 7

  - by NoCarrier

  Ok, this is very strange. Recently, i noticed that every 10-15 seconds, there would be this faint, annoying duh-dum sound coming out of my speakers. (hard to describe. sounds somewhat like the sound windows makes when you unplug a USB device, but not as pronounced and much quieter). I closed every app and ended as many processes as I could, but the sound persists. I look at the volume mixer and sure enough, when the sound occurs, there is a little spike in the level under "System Sounds". I haven't installed any hardware or software in the last several weeks. This started recently - completely out of the blue. Does anyone have any insight?

• Can a RAID 4 disk setup crash if only 1 hard disk fails?

  - by Steve Rodrigue

  I am a web developer. I have not much experience in hardware. For this reason, I use managed servers. This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly. The array was set up as RAID 4. Do you guys ever seen that before? Is it possible? Thanks for any help on this guys. I need to know if my web host is honest with me.

• What should a hosting company do to prepare for IPv6?

  - by Josh

  At the time of writing The IPv4 Depletion Site estimates there are 300 days remaining before all IPv4 addresses have been allocated. I've been following the depletion of IPv4 addresses for some time and realize the "crisis" has been going on for many years and IPv4 addresses have lasted longer than expected, however... As the systems administrator for a small SaaS / website hosting company, what steps should I be taking to prepare for IPv6? We run a handful of CentOS and Ubuntu Linux systems on managed hardware in a remote datacenter. All our servers have IPv6 addresses but they appear to be link local addresses. Our primary business function is website hosting on a proprietary website CMS system. One of my concerns is SSL certificates; at the moment every customer with an SSL certificate gets a dedicated IPv4 IP address. What else should I be concerned about / what action should I take to be prepared for IPv4 depletion?

• 2 HDs in RAID 1 with 2 partitions ?

  - by Prix

  Hi, i am not very familiar with raid partitons and am not even sure if this is the right place to ask about it, but i hope that if it is not that some one can point me on the right direction. This is my situation, i have 2 500 GB hds and a 3ware pci-e hardware for raid and i wanted to make a RAID 1 but i dont know if i can make more then one partition for it, for instance: MAIN HD: os partition: 100GB data partition: rest of left size and make the RAID 1 either work on all the HD or just on the data partition of it. that is on windows xp sp3 and the 3ware allows bootable raid.

• Is it possible to live-boot VirtualBox from a USB flash drive?

  - by bw.

  To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

• How to achieve redundancy across data centers?

  - by BrandonBT

  I have a LAMP server with a lot of hardware redundancy built in. I am not worried about the server becoming unavailable. What I am worried about, however, are potential network issues in the data center the server is in. What I would like to have is another server in another data center for redundancy. Load balancing is less of a concern. With that said, I am relatively clueless on two points: How to have two servers in two geographically separate data centers that have exactly the same data, in terms of both files and MySQL databases. How to ensure that all traffic coming into one data center are automatically transferred to the other database in the case of a network or server failure at the first data center. Any guidance on how to accomplish the above two problems would be greatly appreciated.

• VMware Workstation 7&8&9 does not generate /etc/vmware/network upon installation

  - by dash17291

  When I install VMware Workstation on Arch linux Virtual ethernet is not working. $ sudo tail /var/log/vnetlib Aug 28 22:20:33 VNLFileExists - Cannot check for file or directory: /etc/vmware/networking , error: No such file or directory Aug 28 22:20:33 VNLNetCfgLoad - Import file does not exist Aug 28 22:20:33 VNL_Load - Error loading the vnet configuration, file used: /etc/vmware/networking Aug 28 22:20:33 VNLNetCfgUnload - Requested cache is not loaded Database file is not present.

Previously I have copied that file or directory (I don't remember) from a working installation, but now I need a real solution. It's strange for me, may be a hardware issue also because with Ubuntu the same thing happens on the same computer.

• dd cloned win2003 std ntfs partition, "no operating system found".

  - by 3molo

  I cloned an existing ntfs partition on faulty hardware using dd and gzip. The copied partition was then written to a newly created ntfs partition on a new disk (on another server) and the bootable flag was set. However, the "Operating system not found" (or is it No operating system found?) is what happens when I try to boot it.The faulty server is part of the AD domain, but I do not have the local administrator password, so I couldn't use the repair console of windows 2003 to fixmbr. I did try to do a normal repair during win2003 installation menu, but with no success. Both windows installation and Linux recognizes it as a ntfs partition of its true size, and files can be seen and read. I've done this a couple of times before, but I didn't encounter this problem. Of course I encountered other problems, like BSDO due to lack of hw drivers etc - but that was pretty easily fixed. Why am I failing to get the copied partition to even be recognized as a bootable disk on the new server?

• SNMP - So I have a MIB. Now What?

  - by senfo

  I can't seem to get my head wrapped around the purpose of a MIB. I have a collection of ~20 MIB files that were supplied to me by the vendor, but what do I do with them? I also have a few OID's that were supplied by the vendor that don't seem to be valid. When I issue an "snmpget -v1 -c public 192.168.0.123 .1.4.6.3.2.6.2" (assume that's a valid OID), I get an error indicating the variable is unknown. Does this sound like a hardware configuration problem? Do I need to "load" (for lack of better words) the MIB into the device? Unfortunately, the vendor has been completely unresponsive with returning emails to my questions, so any help would be greatly appreciated.

• Fastest OS for Java applications

  - by user33408

  Hello I have a multithreaded Java program. I am dealing with certain perfomance problems. I have improved everything. Hardware + Software. Now I think that it's time to move to proper Operating System. I was wondering, what OS is the fastest for Java Virtual machine? I am using Sun Java6. Do you think that Sun Solaris would be the best choice for Java applications? Or FreeBSD? or CentOS (I am using it currently)? Thanks

• No External Sound

  - by Walter

  I have ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal did alsamixer seems to recognize my soundcard, though the driver is not listed in system - admin -hardware drivers, the only driver listed is my graphics card. I have tried several forums and it seems no one is interested in responding to sound issues. Here's hoping it is different here.

• 'hijacking' gui and mapping certain controls to certain functions. VNC. TouchOSC

  - by Nick

  I need a VNC LIKE application which rather than sharing the screen, can take control of a specific application and then share that functionality across a network to multiple clients. Obviously, VNC requires use of the mouse and therefore only one user can do something at one time, this is NOT what I am after. I am after something that can hijack the graphic user interface, map certain controls, and then display them in another piece of software (perhaps like TOUCHOSC) The software I would like to map and share is called YAMAHA STUDIO MANAGER and is used to control certain Yamaha audio hardware, and in my case a Yamaha LS9 and M7CL mixing console. Its free.

• Can't unlock locked screen, in Ubuntu 12

  - by Camille Goudeseune

  After locking the screen (with a keystroke bound to xlock -nice 8 -mode blank), I can unlock the screen as expected, but only within a few minutes. After being locked overnight, when I hit a key (even Ctrl+Alt combos), the screen stays black with just a brief white flash across the middle of both monitors. The workaround is to ssh in from another host and restart X. Some months ago, this happened every few weeks. By now it happens almost every morning. How do I even start to diagnose this? What might I look for in log files? (The intermittency is particularly troubling.) Failing that, is there an alternative to xlock aka xlockmore? Hardware: 3-year-old HP minitower, GEForce 9800 GT, two Asus LCD monitors. Software: Ubuntu 12.04.2 LTS. Window manager awesome-wm. NVidia driver 304.88. XLock version xlockmore-5.31.

• Windows XP - non-user input data filter message after installing wireless keyboard & mouse

  - by James

  After I installed MS wireless keyboard and mouse and associated software, I started getting this annoying message titled "Hardware installation" telling me the software I am trying to install did not pass the XP logo tests. The software is for "HID non-user input data filter" and I have two options Continue anyway or stop installation. Now, if I try to continue the installation fails, if stop installing another message pops up with a little mouse logo and the whole process repeats itself. after I am done with that message a third dialog appears. This is happening every time I boot up my PC (a desktop), I tried following an advice I found in some forum and download windows update for ID non-user input data filter, but that installation failed as well. The thing is, that both keyboard and mouse are working fine Is there anyway to get past these dialogs ?

• Running RAID on an internal storage drive

  - by Johnny W

  I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to put my documents on a "normal" HD running under RAID 1. I have four SATA 3GB/s ports on my motherboard (my Windows 8 SSD drive in on a different 6GB/s controller). All four are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive. In my BIOS I can only change settings for the entire controller, not just ports. So my question is: If I turn these four ports into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will a HD or Bluray drive be slower/incompatible with being plugged into a non AHCI SATA port? Thanks.

• Extremely poor WiFi reception on new desktop

  - by guy

  I just received a new desktop with a built-in WiFi card (Windows 7 Home Premium x64). However, I am only able to receive any WiFi signal when the computer is within 1-2 meters of a router. Even then, the signal is very weak (Windows 7 says it is "poor"). I have tried this with 2 different routers and see similar results. I have somewhere around a dozen other devices that can connect to both routers with greater signal strength (usually full strength) from much, much further away. When I tried calling support I was instructed to reinstall my drivers and attempt to change the WiFi channel of the router. Neither worked. I was then told that the problem was with my routers and that the computer was functioning normally and that it was certainly not a hardware problem. What would be the cause of this and is there anything I can do to fix it?

• What SATA drive should I install FreeBSD onto? i.e. ar0 vs da0 vs ad4/5

  - by Matt

  I'm installing FreeBSD 8.0 on a server that has hardware SATA Raid. I'm just wondering. What is the difference between these devices. i.e. ar0, da0, ad4, ad5 I take it that ad4 & 5 are my two disks. Somehow the OS can see them individually even though it's one logical mirrored drive. Should I be installing it onto ar0 or one of the adX disks. What is da0? it's smaller than the others. ar0 is not some kind of software raid device is it? Just want to make sure I don't mess this up right from the get go.

• What do you do with a 15 node decommissioned Itanium cluster?

  - by Gomibushi

  We are decommissioning a 15 node Itanium cluster. We don't know what to do with it. Being geeks we want to put it (or its individual nodes) to some cool use, but since it is Itanium we are a bit unsure what that could/would be. We are not bringing it back as production servers and we are considering giving them away, if anyone wants them. It's not the most spiffy hardware, but being 2U rack servers they pack an ok amount of cpu and memory, they're about 3 years old perhaps. Ideas to what runs well on them? Or something one can use them as?

• What are the current options to encrypted a partition on mac os x ?

  - by symbion

  I recently got my laptop stolen with some sensitive informations on it (personal source code, bank details in a secure file, passwords, etc) and I learnt the lesson: encrypt your sensitive data. Now, I am wondering what are the options to encrypt a partition (not an encrypt disk image) ? Aim: The aim is to prevent anyone (except me) to access those data. Requirement 0: The software must be able to encrypt non system partition. Requirement 1: Plausible deniability is required but preventing cold boot attack is however not an absolute requirement (I am not famous enough or have sensitive enough info to have this kind of requirement). Requirement 2 : Software taking advantage of AES hardware encryption are very welcome as I intent to get a Macbook Pro with i7 CPU (with AES-NI enabled instructions). I will have avirtual machine running in the encrypted partition. Requirement 3 : Free or reasonably cheap. Requirement 4 : Software must run on Mac OS X Snow Leopard or Lion. So far, TrueCrypt is the only option I have found. Regards,

• bad switchs duplicate my ip

  - by tacoen

  I had a large area LAN. There were many switch and AP on it, then somehow I couldn't ping my servers, and it's said that the IP was duplicated. I use arpwatch and found out that one of the switch flip-flop-ing the IP. I isolated that troublesome switch using his mac-address. But, since this a large area LAN... I doubt this will be the last cases. If there any software or hardware that I can use to prevent this kind of error? Sorry for my bad English.

• How can I upgrade from Windows 8 x32 to x64 fastest & easiest?

  - by parkviewK

  I was upgrading the hardware in a family member's computer and purchased the Windows 8 upgrade for $40 from their website. Not thinking, after I installed it I realized I now have 32bit Windows on this 64bit capable machine. Did some research and it appears that the upgrade assistant just gives you whatever architecture you were uprgading from (windows 7 32bit). Question is, what is my best option here? I have already purchased a key, will this work on x64? I'm considering installing Windows 8 Preview x64 and upgrading from there, but not sure if that will work or if it will make me purchase it again.
