• Nvidia driver on Windows 7 causing black screen

  - by inKit

  I have just installed Windows 7 on a desktop machine and for the first time ever have had a really tough time doing so, its normally a nice smooth install. This time I found that the monitor would simply go black after completing the installation. I tried reinstalling about 3 times and this did not help. After much searching I discovered that it was the nvidia drivers that were playing up with win 7, so i booted into safe mode, disabled the device, then rebooted to complete the installation. Windows 7 now works fine as long as the nvidia 9600 gt video card is disabled. The moment I enable it, the system requires a reboot and the screen will go black before even getting to the log in screen. I have tried downloading the latest driver and installing it manually, I have also tried uninstalling the device and allowing windows 7 to install it itself. Nothing seems to work. any clues?

• Can I Store MediaWiki Files on the cloud?

  - by user219048

  I recently got a chromebook, and I've been brainstorming different ways to put mediawiki on it (with localhost, not a server). One way I've read about online is to go into developer mode to download and set up LAMP. I was wondering, wouldn't I be able to store the apache, mysql, php, and mediawiki files on the cloud (google drive)? And if so, would anything prevent me from accessing my wiki on any other computer's localhost, assuming I could just log into Google Drive to access these files? Might there be any reduced performance when operating from the cloud?

• Slow speed for UFS mounted drive in Linux

  - by Incredible

  Hi, I have a disk that has Sun OS disk, (ufs filesystem). And I want to mount it in my debain machine with read/write mode. Since by deafult linux doesn't support write to ufs filesystem. I had to recompile the kernel by setting to the flag CONFIG_UFS_FS_WRITE=y. Now I am able to write to the filesystem, but the read/write speed is very slow. It is around 120 KB/s. Any idea what is wrong and how to resolve this issue? Thank you in advance.

• Why does MS-DOS tells me I need extended memory and thinks a file is read-only? [closed]

  - by Jake Inc.

  I am running a .COM file on a MS-DOS 6.22 boot USB drive When I run it on my laptop the program works fine but when I run it on my desktop I get error 40 not enough extended memory. When I go to the memory tab in GUI I try to switch none to auto, but I get the error "This file might be read-only". It's not read-only, when I put it on my desktop I change the settings and the new settings are in a .pif I can't run .pif in MS-DOs so I need to Change the .exe not create a .pif. Change the amount of extended memory all files have on my MS-DOS. On my laptop there is no memory tab, the only real difference is my laptop is x64. Thanks for helping but I think teh x64 bit has nothing to do with it I dont eve nthink iits in 64 bit mode because Im using a boot USB. What i need to is listed above, thanks for helping.

• Why my USB mouse get suspended after 3 seconds of inactivity?

  - by Vi.

  Mouse's bottom LED goes off after 3 seconds after connection and cursor movements and wheel stops. Pressing any button, reconnecting or resetting USB device resumes it for another 3 seconds (when resumed by pressing button, this event does no go to X). This happens when using any of USB ports. This mouse works well with other computer with Linux. It was working well before. Why can it happen? How to fix it? Update: It happens only if laptop is on battery. Answer: this is caused by powersaving done by laptop-mode-tools. To temporary turn off powersaving one can use for i in /sys/bus/usb/devices/*/power/control; do echo on > $i; done

• How to prevent Excel rounding numbers or adding redundant 0's?

  - by Highly Irregular

  I have a column of numbers that appear like this: but the actual value of the shown cell is 20130.153334 Other values have a different number of decimal places. I don't want to add redundant 0's, so I can't just specify a particular number of decimal places to display. I really just want to treat the values as text. I have already changed the format of the cell to Text, as the description for Text is: "Text format cells are treated as text even when a number is in the cell. The cell is displayed exactly as entered.". However, it clearly isn't being displayed exactly as entered! Strangely, if I hit F2 on the cell to go into edit mode, then hit enter, it is then displayed correctly. I can't do this manually for 2000+ records though! How can I prevent the numbers being rounded?

• Windows/global setting to allow only SSL when on public Wifi?

  - by hungry

  Rather than going through each of my apps and modifying settings, or tweaking individual browser settings (I use three different browsers) or just being careful not to type non-SSL URLs into the web address bar, is there a solution at the Windows level that will prevent anything from connecting to the web from my laptop unless it's using SSL? I also have mini apps installed like Gmail checker, etc that connect to the web of their own volition using my usernames, passwords and such, so it goes beyond just web browsers. The reason I'm asking is I want to work securely on the general Internet when on public Wifi (e.g. coffee shops) without a lot of hassle or having to remember everything that needs to be locked down. When I'm back home I want to go back to full access mode using any kind of protocol on the web. If a website doesn't support SSL when I'm out in public then I just don't surf it - that's not a worry to me.

• Vagrant sahara plugin - multiple snapshots

  How I can make more than one snapshot when in sahara sandbox mode? Or, can I see list of all commits I've ever made and rollback to any? Why do I need all this? I just want to setup initial VM. After that I want to compile number of packages from sources, and this takes pretty long time. So right now I thinking of this order: Setup initial ubuntu 12.04 vagrant box Snapshot this state Compile sources, install system wide rbenv (it make compilation also) Snapshot second state Start all my infrastructure experiments Rollback to any of my previous states or commit third state

• Why are my favorite websites becoming slower, over months?

  - by Wolfpack'08

  I spend a lot of my time at sites for watching online videos: youtube, gorillavid, thedailyshow.com etc. I used to watch the videos in full screen mode, and then that became very laggy. So, I started watching them with full-browser zooming. Then that became laggy. Recently, I've had to actually zoom out; otherwise, the video will lag so much that my PC locks. Could this be a symptom of my processor, RAM, or motherboard going bad? Has it, perhaps, anything to do with softwares like Chrome or the playeres the sites are using being updated?

• SSH tunnel doesn't work

  - by s1ck

  I am trying to use my server as a "proxy" with ssh. However, setting up tunneling with ssh -D localhost:8000 user@myserver does not work. I tested this on various machines with ssh and putty - It connects just fine, but when I set my browser settings accordingly, I just get an error "Connection has been reset". I tried monitoring the traffic with wireshark, but I didn't even see some tunnel-traffic. I explicitly set AllowTcpForwarding to "yes" but I still can't use the tunnel. When running ssh in verbose mode, I don't get any errors but debug1: Connection to port 8000 forwarding to socks port 0 requested. debug1: channel 3: new [dynamic-tcpip] debug1: channel 3: free: dynamic-tcpip, nchannels 4 What am I doing wrong?

• Can I sleep one of the displays on a dual-monitor setup? [duplicate]

  - by archedpenguin

  This question already has an answer here: Can I sleep one of the displays on a dual-monitor setup (running Windows 7)? 4 answers I want to be able to 'put the display to sleep' on one of my two monitors when it isn't needed, so it doesn't distract me or use unnecessary power. Ideally, the display would be asleep, but the OS would remain in dual-monitor mode, so I could still have a variety of windows open in the sleeping monitor's display space, which would mean I wouldn't have to keep switching between single- and dual-monitor modes. Its the same as "Can I sleep one of the displays on a dual-monitor setup (running Windows 7)?" I just wasn't sure I could comment on such an old thread. None of the answers there provided a perfect solution and I was wondering if there is now a solution available.

• Windows XP - Website unaccessible on single pc in LAN

  - by DorentuZ

  For serveral days now, a website isn't accessible on a single pc in the LAN. On the other pc's, it works just fine. And it's just a single website that's not accessible as far as I know of. The website generates a timeout on every single web browser I've tried (IE8, Firefox and Chrome). However, traceroute, nmap and telnet all work just fine. I've even tried multiple user accounts and safe mode, but that didn't work either. As a side note: using a linux live cd did work and I could access the website without any problems. The hosts file is the windows default, the ip- and dns settings on the network adapter normal as well. No strange processes are running and no viruses found. According to tcpview and netstat there are connections to the domain, but every request in the browser results in a timeout.. Any idea what's happening?

• Hyper-V with a single host NIC

  - by Cylindric

  I'm trying to create a simple Hyper-V test machine, and am having more problems than expected with the basic networking. All other hypervisors I've used (vmware server, vmware player, virtualbox) allow me to use the default single NIC in my machine, and then create guests with "bridged" mode so they appear like a normal machine on the network. With the Hyper-V server, when I create a Virtual Switch and set it to "external", I lose all network access from the host. The solutions I've seen online seem to rely on complex configurations requiring multiple vSwitches and RRAS on the host to get it going. Is it really that complex to get a simple, single-NIC Hyper-V server going, in such a way that I can still use the host? The host is Windows 8.

• Vista Startup - Cannot Find the File Specified

  - by Redmastif

  Yesterday I restarted my laptop because my Wi-Fi catcher wasn't working correctly, and when the computer reached the login screen, instead of showing my user account it said "Cannot find the file specified". I rebooted and ran the Startup Repair and Memory Diagnostics but nothing showed up. I also took the battery out for a minute and tried again but still no luck. The weird thing is that I cannot even boot into safe mode, it still shows the same error. I don't remember downloading or opening anything suspicious recently, and I have 3 different cleaners/anti-malware programs as well that I usually run about once a week. I did go into the registry recently but I didn't modify or delete anything as I was only checking to see if I had a certain key in it. I have a Dell laptop running Vista Home Basic SP2. If I have to I can reinstall the OS with the CD or even take it to Best Buy but I'd rather try and fix it first. Thanks.

• OS won't boot during vs2010 install on vista 64

  - by Noam

  I am installing vs2010 on a vista 64bit machine. During the install it asked for a restart. Since that, vista won't load. I tried restore to previous good config - didn't help. I am only able to boot it using safe mode with networking. When I did that, it continued the vista part of the install (the screen with the 3 out of 3 updates) but after that when I restarted again - still fails. HELP!!!

• Can't boot into my Windows 7 64-bit Acer laptop

  - by John Smith

  Boot normally -- it hangs on "Starting Windows" animation forever. Boot safe mode -- it bluescreens. Boot with a recovery CD (or try Repair Installation directly without a CD) -- it hangs on the green loading bar forever. I dual-boot Ubuntu and can get into the Ubuntu partition fine so I don't think anything is necessarily wrong with the harddrive, but the Ubuntu partition is tiny and I rarely use it and can't access my Windows files anyway. Is there anything I can try that'll help repair whatever happened? I just want to run a checkdisk utility or something similar that'll repair whatever got botched.

• Vim equivalent to Emacs C-i?

  - by Culip

  Does Vim have a command equivalent to Emacs' Ctrl-I? Emacs has an extremely useful shortcut "C-I" which fixes indentation of the current line (or selected lines.) For example, suppose you write this tiny code on Emacs: def foo print "boo" end and you are selecting the whole 3 lines. You press "C-I" then the code becomes def foo print "boo" end I can use this in quiet mode i.e. ignoring. Emacs as well. Does anyone know how to do this on Vim?

• Is there any way to make an external monitor the primary under Boot Camp?

  - by mmc

  This may be a general problem for all Windows XP portables, I don't know, I don't have a dedicated Windows portable. I'm running a MacBookPro Unibody (so it's using the Nvidia 9600M chip under Windows XP SP2). Is there any way to get my external monitor to be the "main"? Even when I use the Nvidia Control Panel to move the task bar to my external monitor, games still refuse to run on anything other than the internal monitor. (In full screen mode, of course, if it's in a window, I can drag it to the other screen, no problem) I know I'm missing something elementary here.

  I have VirtualBox Portable installed from vbox.me. I moved it on a USB drive and added a virtual Ubuntu. It works fine on the computer I created it, but moving the usb drive to a different the Ubuntu does not start any more. I already changed location descriptions in <machine>.vbox and the VirtualBox.xml. When pressing Shift while starting the GRUB loader comes up, so I tried the recovery mode.
