• DVD drive won't work after installing software

  - by Dan

  DVD drive was already region-free but for some reason would not play a certain DVD as it was the "wrong region". This is the first time I've played a DVD on the drive, but I've imported a lot of CDs before and they always worked fine, even CDs bought from the USA (I live in the UK). To get around this, I downloaded a piece of software called "DVD Region Killer". (Clicking the link won't start the download, so go ahead and check it.) After this, the drive isn't recognised. It won't show up in "My Computer", and when I insert a disc it will start to whir but not take action, i.e. iTunes won't recognise that I have put a CD in. In the Device Manager, the drive shows up with a caution-sign. The device status reads: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Disabling, uninstalling and reinstalling does not help. Clearly the software download is the issue, but it is difficult to remove. The only files I can find in Program Files are: C:\Program Files (x86)\Elaborate Bytes\DVD Region Killer which contains a changelog and a HTML document which has no info on uninstalling. It doesn't show up on "Add or Remove Programs", or even as a background process when I press ctrl-alt-del. Apparently it has no interface as such, and can be accessed by an icon in the system tray, (see review in link) but I don't see the icon. If it helps to know, I have a Dell Inspiron running Windows 8 64-bit, and the model of the DVD drive is: MATSHITA DVD+-RW UJ8C2 Thanks in advance.

• Emptying Windows temp folder is a good idea?

  - by Siva Charan

  Am using DELL Inspiron with Windows 7. As far as I know emptying the windows temp folder would be good. But I faced a strange behaviour around 8 months back, when I clear my windows temp folder. The next day onwards, my laptop starting displaying daily one or other errors and one day OS got crashed. Till now I am not sure whether OS got crashed due to clearing the windows temp folder or something else is problem. Here Windows temp folder mean "C:\Windows\Temp" This is the behind the story. Today, this temp folder "C:\Windows\Temp" contains 102 GB Most of the space occupied by the files starts with etilqs_*.*. I came to know that these files are generated due to WD SmartWare. Now my problem is:- Actually I want clean up this folder, since it occupies lot of space. If I clean up "C:\Windows\Temp" folder, will my laptop face the same kind of problem which I faced earlier OR Any new problems will occur? Please suggest me a good solution.

• Browsers behaving very strangely/not working in Windows Vista SP 2

  - by Kim_guest

  Sorry, that I'm posting this as a guest, but I couldn't log in. Maybe you can help me. I had a virus and gave this inspiron 1525 laptop to a computer expert, who removed it. I think he reinstalled Windows, because when I got it back IE 7 was installed. So after 3 hours I installed SP 1, SP 2, IE 9 and Google Chrome. First when there was only SP 1 and IE 7 installed, I could only use Google in IE, and I had copy the links download links of the updates (Update center didn't work) over to Google Chrome to download it there, because I couldn't do that in IE. Now I can't use Google at all, but strangely Bing works. Also I can display certain pages, but not all (I could open StackExchange, but not the login page; that's why I'm posting this as a guest). Another strange thing is, that now a webpage either works in both browsers (I couldn't install Opera, because the installer says it can't download the files) or in none. It is a 32 Bit system. It would be nice if you could help! I hope I will be even able to post this question...

• What to do with old laptop screens?

  - by Lord Torgamus

  This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses need not be geared towards those particular models' screens. Rules, based heavily on the original question's: Objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, be plain ol' fun, serve a social purpose or benefit the community. Your answer need not be limited to only one screen. For a really good answer, I'll go out and buy additional leftover screens. Your answer need not be limited to one project per screen. If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a useful purpose; art is nice, but functional art is way better. Thanks in advance, folks. EDIT: Found another related question. Fun projects to do with an old 17" LCD monitor EDIT 2: I, for one, am enjoying the new outpouring of creativity here. Best fifty bucks... I mean, rep points... I ever spent. EDIT 3: That does it. At the end of the week, there was a tie for most votes between the accepted answer and the game platform answer. The game platform answer was cooler, but less reasonable as a project to actually do; in other words, it was more moon rocky. Unfortunately, I think fencepost had the best comment on the topic, which is that displays on their own have no good interface. Thanks for playing, everyone!

• How do I reformat/reinstall an OS on a hard drive after its been wiped by eban?

  - by Aggrevated

  I am trying to install XP SP2 Home on a Dell Inspiron 531s. Yes it came with Vista but I happen to own a legal copy of XP. I bought the hard drive off eBay(used). I changed the bios settings to boot from CD and when I start up the computer it goes to the hard drive which says its been cleaned using eban XX.XXX.XXX. My problem is that I can't get the PC to boot from the XP disk. I have tried putting the disk into another PC it works. I have put the bad hard drive back in and the dvd+rw works. I am really stumped and am beginning to think that the hard drive is unusable. I only have the sata cords for 1 hard drive to be hooked up at a time. Any ideas or suggestions or confirmation that I can't use this hard drive would be appreciated. Yes I am probably a 'noob' but I have installed XP and Vista many times without any problems. I don't need to be put down on my level of experience I just need answers. Thanks Everyone

• What can cause two "identical" setups of IE8 and XP to display things differently?

  - by ccornet

  This has been baffling me for a while. Of the machines I use in visitting Stack Overflow, two of them are machines with the same setup: Dell with Windows XP with IE8. Since they were issued to me by the same company (one to use in the office, one to use at home), they have identical setups as well. But they display certain page elements differently! One is an Optiplex GX620 desktop, the other is an Inspiron 9100 laptop, but somehow the hardware doesn't seem like something that should be overriding how my browser displays things. Nevertheless, the laptop seems to display things differently than what is expected. Differences have included the following: This issue persisted on the laptop after Jeff fixed it, but was repaired for everyone else and on the Desktop. When viewing Vote Counts on a post, the grey line is left immediately beneath the upvotes but a number-sized white space is below that before the downvotes. On the desktop, it displays properly with the two adjacent and divided by a grey line. Code blocks seem to have a blank line at the end on the laptop. The following image illustrates how the last two elements look on the laptop. So, considering that as far as I can tell, these two setups are identical (I have not messed with any settings and they were both initialized identically as well), what else could be causing the display difference?

• Windows 8 doesn't start up after installation

  - by Raj BD

  I have a DELL INSPIRON n5110 machine running Windows 7 Home Premium 64-bit. It has 6GB of RAM and 500 GB hard disk capable to run any Windows and Linux system. And I recently attempted to install Windows 8 in the machine. Installation goes fine and smooth until the final stage when windows is done installing and GETS DEVICES READY. When GETTNG DEVICES READY reaches about 60%, the screen goes blank with the machine running. After a while it reboots. And after the new Windows Logo with dotted circles are done showing up, the screen goes blank again (when we'd expect login screen to show up). There is not even a cursor. I can see the HARD DISK ACTIVITY LED blinking but nothing shows up in the screen. I've tried CLEAN INSTALL several times. The DVD is fine, it installed and worked well in my friends' laptop PCs. I tried installing both PRO version and ENTERPRISE version and both 32-bit and 64-bit. But the problem was same everytime. Finally, I had to reinstall Windows 7 which installed and ran without any problem. The problem, we can guess, is GRAPHICS perhaps. I have Intel SandyBridge Graphics Mobile Chipset (Intel HD Graphics 3000). But if Windows 7 and Linux distrubutions like Mint and BackTrack can run on the machine, why on earth, would Windows 8 not run?

• unexplainable packet drops with 5 ethernet NICs and low traffic on Ubuntu

  - by jon

  I'm stuck on problem where my machine started to drops packets with no sign of ANY system load or high interrupt usage after an upgrade to Ubuntu 12.04. My server is a network monitoring sensor, running Ubuntu LTS 12.04, it passively collects packets from 5 interfaces doing network intrusion type stuff. Before the upgrade I managed to collect 200+GB of packets a day while writing them to disk with around 0% packet loss depending on the day with the help of CPU affinity and NIC IRQ to CPU bindings. Now I lose a great deal of packets with none of my applications running and at very low PPS rate which a modern workstation NIC would have no trouble with. Specs: x64 Xeon 4 cores 3.2 Ghz 16 GB RAM NICs: 5 Intel Pro NICs using the e1000 driver (NAPI). [1] eth0 and eth1 are integrated NICs (in the motherboard) There are 2 other PCI-X network cards, each with 2 Ethernet ports. 3 of the interfaces are running at Gigabit Ethernet, the others are not because they're attached to hubs.

On the old system, if it couldn't keep up this is where the drops would be. I drop packets on multiple interfaces just about every second, usually in small increments of 2-4. I tried all these sysctl values, I'm currently using the uncommented ones. # cat /etc/sysctl.conf # high net.core.netdev_max_backlog = 3000000 net.core.rmem_max = 16000000 net.core.rmem_default = 8000000 # defaults #net.core.netdev_max_backlog = 1000 #net.core.rmem_max = 131071 #net.core.rmem_default = 163480 # moderate #net.core.netdev_max_backlog = 10000 #net.core.rmem_max = 33554432 #net.core.rmem_default = 33554432 Here's an example of an interface stats report with ethtool.

With and without, it's the same. This is what my interrupt stats looked like before the upgrade, after, with ACPI on PCI it showed multiple NICs bound to an interrupt and shared with other devices such as USB drives which I didn't like so I think i'm going to keep it with ACPI off as it's easier to designate sole purpose interrupts.

I can't figure out why my PCI-X slots are negotiated as PCI. The network cards are all PCI-X with the exception of the integrated NICs that came with the server. In the output below it looks as if eth3 and eth2 negotiated at PCI-X speeds rather than PCI:66Mhz. Wouldn't they all drop to PCI:66Mhz? If your integrated NICs are PCI, as labeled below (eth0,eth1), then wouldn't all devices on your bus speed drop down to that slower bus speed? If not, I still don't know why only one of my NICs ( each has two ethernet ports) is labeled as PCI-X in the output below. Does that mean it is running at PCI-X speeds are is it showing that it's capable? # dmesg | grep e1000 [ 3678.349337] e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI [ 3678.349342] e1000: Copyright (c) 1999-2006 Intel Corporation.

• RAID 5 RECONSTRUCT with RAID Reconstructor

  - by user22914

  I have Dell Poweredge server 2600 with Raid 5 in 3 hard drive Scsi 36gb each, it was fail to boot sinc the third drive is offline. I attached Sata card adapter to Sata hard drive and install OS SERVER 2003 to it, downloaded drivers for Raid and everything goes fine when I use recovery data software called "GetDataBack" from here http://www.runtime.org/data-recovery-software.htm but the problem that not all data recovered, I am still looking for importants data with about 5 GB size. I have another software called "RAID Reconstructor" from "http://www.runtime.org/raid.htm" I thought if I run it to reconstruct that will help to recover more data and put the third drive to be Online but I am afraid that might erase the current data in the other drives. Please I need your advise in how I could retrive the remaining data? Thanks

• How to change RDS licensing mode from 'per user/device' to 'Remote control for administrators' on Wi

  - by Prashant Mandhare

  We have installed windows 2008 R2 enterprise on a Dell server. This server is placed remotely in data center and only administrator is going to access it for maintenance purpose. No multiple users or client remote access is needed Now during 'remote desktop services' role installation network admin accidentally selected 'per user/device' licensing mode. Because of which now 120 days free try period is ticking. Since only administrator is going to access this server remotely we need to have 'Remote control for administrators' licensing mode (like windows 2003) on it. How we can change licensing mode from 'per user/device' to 'Remote control for administrators' on 2008 server? Also will it be possible to do this change remotely using RDC session itself? or do i need to change it using physical console (if remote access is gonna be disabled during switch)?

• How to disable Bluetooth auto-answer on Windows 7?

  - by MarkR

  When my BlackBerry 9630 is connected via Bluetooth to my Dell desktop running Windows 7 x64 there are a bunch of Bluetooth services enabled on Windows Advanced Audio BB Bypass service BB Desktop Service Dial-up Networking Headset Audio Gateway Remote Control Remotely Controlled Device When a call arrives on the 9630 Windows immediately answer the call. This is annoying when windows answers the phone before I even hear an audible ring and the hapless caller is saying, "hello. hello" on top of music I have playing. Does anyone know how to tell Windows not to answer the call? I want to be able to don my headset, switch audio to my headset, THEN manually answer the call.

• Recommendations on laptops - long battery life, slim, Windows 7

  - by molecule

  Hi, I have been looking at a couple of laptops... The most important requirement is long battery life, slim & light, and runs Windows 7. One that seems to fit the bill is the Sony Vaio Z series laptops. They claim to have long battery life, have some really impressive specs (on paper) and a very nice design. They are not on sale where I am yet but has seen/used them? Second would be the Lenovo Thinkpad IBM x301 For business users, Thinkpad seems to be the way to go. I have also considered Dell Alienware M11x but may not be completely appropriate for business use? What would you recommend with a budget of USD1500-2000?

• How to preserve sysprep from changing Default User settings

  - by user33794

  I'm having diffculties configuring 20 new Dell Vostro minis here. I set up one of them with my preferred OS, applications and settings, especially the Visual Effects Settings of Windows XP. I set them to best performance and deactivated everything else in the box. I copied this profile to Default User Profile and did sysprep -mini -reseal. After capturing this image and deploying it again, the desktop settings are correct except the visual effects settings. fading and everything else is reenabled for each new user which is created on the system. How do I preserve my settings from being overwritten by sysprep? thanks!

• w2k3 chkdsk errors as vmware 1.8 guest

  - by Sean Kirkpatrick

  We have two Dell servers (CentOS 5.x) hosting a variety of VMs including 3 W2K3 and 1 W2K servers as guests as well as a handful of other Linux guests. Each Windows VM has 2 drives, C: and D:. on 2 of the W2K3 and the W2K boxes we have recurring errors appearing on a daily basis as reported by CHKDSK. We'll run CHKDSK /f and reboot all affected machines and the errors are reported as fixed. The next day CHKDSK will report the same errors. None of the linux guests nor either host report errors when the are rebooted. The RAID controllers are not reporting errors. We're beginning to think that these are phantom errors somehow, but I'm not willing to go to the bank on that just yet. Anybody have similar experiences or advice? Thanks! Sean

• Problems with 2 ISCSI connections esxi 3.5

  - by rphilli5

  I am running a dell poweredge 1950 with 4 nic cards. 1 is bonded to SAN #1 on 192.168.90.xx. The second SAN is on a separate network - 192.168.7.xx The network adapter can view the ip range of the san and the NIC can be pinged from 192.168.7.xx range. vswitch1 and vswitch2 are configured identically except for the ip address. The second SAN has been added to the iscsi software adapter but the SAN is never recognized. I can connect to the SAN from other machines on the local network. Is there something else that needs to be configured for the iscsi software adapter to know which vswitch to use?

• 8Gb Fiber Channcel HBA vs. 10 Gb SPF+ Converged HBA

  - by Hossein Aarabi

  I am putting a Dell server together, more specifically R720. I have to select the correct Host Bus Adapter. This HBA on R710 will connect to a storage device. I am confused between these two: QLogic 2562, Dual Port 8Gb Optical Fiber Channel HBA (price $2,045) QLogic 8262, Dual Port 10Gb SFP+, Converged Network Adapter (price $1,618) I thought since the QLogic 2562 is a fiber channel and is more expensive then it is faster in terms of IOPS. But, it is a 8Gb as opposed to 10 Gb of SFP+. My questions: Which one is better (IOPS performance, etc.)? Why should I choose one over another?

• How to charge an iPhone on a Windows PC without Installing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• 3 Monitors powered from a Nvidia fx580

  - by user26067

  I have a NVidia FX580 card in a Dell Precision T1500. The outputs of the back of the card are DVI and 2x displayport. I tried to run 3 screens from the DVI + 2x displayport to dvi adaptors, but the card won't have it... It'll only run 2 of these screens at the same time. http://www.nvidia.com/object/product_quadro_fx_580_us.html says; **Display Support:** Dual Link DVI-I 1 DisplayPort 2 # of Digital Outputs 3 ( 2 out of 3 active at a time ) # of Analog Outputs 1 To me this reads that it will be able to power 2xdvi monitors and 1xvga monitor. Anyone care to confirm or speculate?

• What would be the optimal disk config for SQL Server 2008 R2?

  - by Kev

  We have a new Dell R710 server that came with the following storage configuration: 8 x 146GB SAS 10k 6Gbps disks 1 x Perc H700 Integrated Controller (2 x 4 disks - 2 ports each supporting 4 disks) What would be the optimal configuration if we were just after performance? What would be the optimal configuration if we were after performance but wanted data resilience. As per 2 above but with a hot standby disk? We plan to run Windows 2008 R2 and SQL Server 2008 R2. Maximising storage capacity isn't a prime concern.

• Can I flash a PCI-E device's Firmware in a VM if the VM has exclusive IOMMU access?

  - by RibaldEddie

  I have a PCI-E Dell Perc 6/i RAID card that I'd like to flash with the latest firmware. Apparently I need either a Redhat / Centos OS or Windows in order to flash the firmware, but I have a VMWare 5.0.1 ESX hypervisor installed on the box and a CentOS guest OS. My motherboard support IOMMU and I have successfully used VMWare's PCI Passthrough feature to give VMs exclusive access to a PCI-E device. Is it safe to flash the firmware of a PCI-E device if that device is passed through to a single VM using the passthrough feature of VMware? Or should I boot one of the supported OSes directly on the bare metal?

• Real VNC won't connect to OS X Leopard VNC server

  - by Pselus

  I have 3 machines. 2 Macs, 1 Dell. 1 of the Macs is running as a VNC server and the other Mac connects great with Chicken of the VNC. Sadly, this app does not exist for Windows so I'm using RealVNC to view from Windows. I connect the exact same way as with the Mac, but on Windows when it connects, I see a program pop up and then immediately close. I have tried all options available on RealVNC and nothing changes things. Anyone have any idea what I can do to fix this?

• Recover lost NTFS partition on SSD

  - by Emil

  Hello, About 2 month ago I upgraded my Dell Latitude E6500 laptop with a Corsair Force F120 SSD drive. Everything worked well until about a week or so back. I started the computer and was faced with a beep and a message saying "No boot sector on Internal HDD (IRRT). No bootable devices". Since I figured that the boot sector had somehow got corrupt I tried booting from the Windows 7 dvd in order to repair the boot sector. But the Windows 7 installation program only found a blank drive with 111GB of unallocated space. I panicked and brought the drive with me to work to let a colleague have a look at it. We made a disk image of the entire drive and ran the drive through Testdisk in Linux. Testdisk did not find any partitions. It appears that the drive has been completely erased... What has happened? What is causing this behavior on an SSD?

• Broadcom NIC Teaming with Hyper-V R2

  - by Brian McCleary

  I have read a few contradictory articles regarding support or at least configuration with teaming of Broadcom NIC's and Hyper-V. I have a pair of Dell R805's with 4 Broadcom 5708 NIC's in them. I have teamed them up (one team for public connections and one for private connections) and I have installed Hyper-V. I am getting some intermittent connection issues though and I'm concerned that it might be due to the teaming. Basically I am wondering if anyone has successfully setup NIC teaming in the parent partition and used the teamed adapters through the Hyper-V switch. If so, what is the configuration/proper steps that you used to configure this. I have the server running Windows Server 2008 R2. Right now the server is in test mode, but my concern is that we won't see any issues until we move it into production and get some heavy traffic on the ports.

• Wireless and Wired Network Access at same time?

  - by grasper

  At work, I use a laptop. It is a Dell Latitude D630 with Windows XP. I work in a lab environment where I need to use the Ethernet Port as a Static IP to interact with a local network (which cannot talk to the outside world). What I would like to do is use the Wireless as the internet connection so i can check email, etc at the same time I am using the ethernet network... It seems like this is not possible. Is there a piece of software or a way to configure it to allow me to do this?
