• Black screen with cursor after BIOS screen

  - by Radio

  Here is a weird one, Got computer with Windows XP. It's getting stuck on a black screen with cursor blinking. What did I do: - Boot from installation CD (recovery option - command line): chkdsk C: /R copy D:\i386\ntdetect.com c:\ copy D:\i386\ntldr c:\ fixmbr fixboot Chkdsk showed 0 bad sectors and no problems during scan. dir on C:\ shows all directories and files in place (Windows, Program Files, Documents and Settings). BIOS shows correct boot drive. Still does not boot. Not sure what to think of. Please help. UPDATE: Just performed these steps: Backed up current disk C: (without MBR) using True Image to external hard drive Ran Windows XP clean installation with deleting all partitions and creating new one. Hard drive booted fine into Windows GUI installation!!! Then: I interrupted installation. Booted from True Image recovery CD and restored archive of disk C to an new partition. Same issue with black screen.

• How can I sync Access databases and keep them up-to-date?

  - by user327472

  I have an Access database on my server. We split it up and use the front-end database for search data and adding new records or reports in local computer. If we update or add a new record, that writes to the back-end of database. I want to use this database in the other building with other servers. Also, those servers have no direct connection. How can I sync both back-end databases to keep the database data up to date? These details may be useful: It's a big amount of data - about 25,750 client records. I guess there are more than 25 tables at 80 MB.

• Tile sizes in 2D games

  - by Ephismen

  While developing a small game using tile-mapping method a question came to my mind: I would develop the game on Windows but wouldn't exclude adapting it to another platform. What size(in pixels) would you recommend using for creating the tiles of a tile-mapped game(ie: RPG) with the following requirements? Have an acceptable level of detail without having too many tiles. Having a decent map size. Allow adaptation of the game on a handheld(ie: PSP), smartphone or a computer without too much loss of detail or slowdowns. Allow more or less important zoom-in / zoom-out. Have a resolution of tile that permits either pixel-perfect collision or block-collision. Anything from a good explanation to a game example is useful as long as it can fit the requirements. This question may seem a bit simplistic, but I noticed that many Indies game developer were using inappropriate scales scenery. Also sorry for the poor syntax and the lack of vocabulary of my question, being a non-native English speaker doesn't help when talking about computers programming.

• Does installing windows format the hard disk?

  - by Jason

  My Google search for ""does installing windows format the hard disk" returns: No results found for "does installing windows format the hard disk". I was quite surprised. I'm hoping to get a quick answer here. Does an install format the hard disk, and destroy all data, including non-os/s data? -Or do you specifically have to say "format" at some point so you know you are losing everything? [I tried to go to SP3, but it doesn't work on my computer. My SP2 disk is fired. I only have a SP1 disk, with a seperate SP2 package. I can't get to Safe Mode to uninstall SP3 ("Windows XP Setup cann run under Safemode. Setup will restart now.). I don't want running the SP1 disk to destroy any non-o/s data.] Thanks.

• DVI problem with LG L204WT

  - by Holgerwa

  I have a LG L204WT which has VGA and DVI connectors. Until recently, I have used the monitor via VGA, but now I have upgraded the graphics board and switched to DVI. The problem is that each time after the computer starts, the monitor either doesn't show anything (black screen, but doesn't go into standby) or the picture is distorted. I then switch the monitor off and on several times, and at some point it starts correctly and then I can work as usual. This only happens on startup. It is one out of 3 monitors, the other two work fine. It seems to me as if the monitor is not able to synchronize on the DVI signal and either shows a distorted picture or nothing at all. There are no settings in the monitor setup that would change anything. What could be the problem?

• External monitor on old Dell 700m?

  - by Adam Henne

  Okay, linux noob. I installed 10.04 on an old Dell 700m in hopes of using it as a media center device. That seems to work great, except now it won't output to the external monitor. VGA cable works fine, TV recognizes other computers fine, it's the laptop that won't output. Turns out that the 700m, unlike every other computer out there, doesn't have a Fn hotkey to switch monitors. The only way to do it in Windows was to go through the Control Panel. In Ubuntu, though, the Monitor setup won't detect or recognize any monitors. The laptop display works fine, but I can't adjust or add anything. I did a little research and found suggestions for older Ubuntu builds involving the xorg.conf. I tried one out, in spite of my unfamiliarity, and it's screwed the whole display big time. I can fix that with a clean reinstall, that's no problem, but I'm cautious about editing xorg again. Any suggestions? Thank you!

• Windows 8 won't load as it has to

  - by MichaelHefner

  I have successfully installed Windows 8 about eight months ago, and all went well. Only the last change I made ??is to set Startmenu8, to get a more normal for the Windows look. Yesterday, my computer screen went dark blue and the mouse does not seem to work. I changed the battery and reboot. But all I get is my desktop, taskbar, and not ikony.Programmy not appear at the bottom, but do not open the maximum so I can not use them. I have a Dell desktop and run the diagnostics on the F12 at startup. All right in line with this. I want to return to the previous item, but can not get in Windows, to do it. Any suggestions gratefully received.

• How to combine with openvpn, dynamic-ip?

  - by asfasdv

  Dear everyone, I am currently using openvpn to surf online to bypass censorship. Let me show you the initial scenario: before openvpn is turned on: IP: 1.2.3.4 (hypothetical, checked by visiting whatismyip.com/) after openvpn is turned on IP: 10.2.3.4 (this is also checked with whatismyip.com/, I assume this is where the vpn's exit point's IP ) Situation: Once I enable openvpn, I can still ssh into this computer by sshing into 1.2.3.4, even though visiting whatismyip.com/ says it's 10.2.3.4. However, I am on dynamic IP, I run a website, and am using tools (inadyn in particular) which pings the freedns.afraid.org (my dns server) and updates my ip. The messed up part is when inadyn does so, my dns changes the ip to 10.2.3.4, which is presumably the exit point of my vpn. How do I get around this? (Note that sshing into 1.2.3.4 STILL works).

• Samba Permissions

  - by Nelson

  I have Samba set up on a Fedora 15 Machine. All looks well except that there's something nagging and I don't know what exactly is causing it. I have a public share on the server which is accessible by everyone and its permissions is set to 777. When one person opens a document under that share and closes it after working, the other person who opens it can't edit or save it because it opens in read only and shows that it's still open on another computer. What might be causing this and how can I resolve this?

• Chrome opens to untitled blank page

  - by jackncoke

  I am working on a computer that had a lot of malware on it. I removed most of it to my knowledge. Now when I open Google Chrome I get a blank untitled page, with the traditional sign-in URL on top. If I go to the settings, the settings tab opens up blank as well. All pages that I navigate to will come up blank as well. The browser doesn't even perform a postback, it is like it is unresponsive. I did some googling and have seen people with similar errors, but no fixes. IE 8 works great without issues. Re-installing Chrome was the first thing I did! Any suggestions?

• Setting up a transparent proxy with only one box.

  - by Scott Chamberlain

  I am playing around with transparent proxies, unfortunately I do not have two machines to test it out with. The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated. The machine I am using is pretty low end so I would like not not have to create a VM with a second box unless absolutely necessary.

• How do I program a hardware button on my laptop?

  - by daniel11

  So I have a set of touch screen buttons on the top of my laptop's keyboard, (one turns on power save mode, one disables/enables the mouse touch pad, one toggles the wifi adapter, and two turns the volume up/down). However there's another one that opened a file backup utility that came with my laptop. Since I bought my laptop, I've uninstalled that utility, rendering this button useless. Would it be possible to reprogram that button to open another file or program on my computer? And if so, what are the requirements and how would I go about doing it? Thanks in advance!

• preloading RSS contents in thunderbird, before actually reading them

  - by Berry Tsakala

  i have thunderbird 3.x, and i'm subscribed to several RSS feeds. How can I tell thunderbird to load/download any new RSS items in the background? The usual behavior with RSS feeds is that it download the headrs, or few introductory lines from the contents, but only when i'm clicking a feed item it starts loading "for real". I really want to receive the feeds and not to wait for them to load, the same way i receive emails in any email client - all messages are fully downloaded at once. there could be several reasons, BTW. - e.g. if i have short connection time, i'd rather connect, sync everything at once, and read it later. - or if i have a slow wifi connection, it's annoying to wait for each and every message, but the computer is idle while reading.. thanks

• Black screen on Windows 7 right after opening Google Sketchup or Minecraft

  - by Aero

  I get a black screen on Windows 7 right after opening Google Sketchup or Minecraft. I presume there are other applications that cause this too - but I have not tried to open them. The window initially stops responding for a few seconds, before I get a black screen and my Skype call ends abruptly. I have tried waiting for a few minutes but nothing happens. I have to power down my computer and then boot it up again. This is becoming an annoyance, and I don't know what's causing it. Here are my specs, if it helps: My graphics card is an ATI RADEON XPRESS 1100. If you need any more info or if I've missed anything please ask. Thanks :-)

• Installation fails after period of time

  - by Jack Marchetti

  I'm running Windows 7 64 bit, Ultimate. I'm running into a problem where, if my computer is on long enough, I am unable to install any software. For example, if I reboot and try to install something, for the most part, it will succeed. if I try and install something after a few hours/days, it will always fail. Sometimes stating that "a previous install failed..." or "an install is already taking place..." even though there is nothing being installed. This also seems to be making my Windows updates fail at a pretty regular rate. Any ideas?

• Google Music Player doesn't work

  I'm trying to log in on Google Music Player application but doesn't work. I get the message below: Login Failed Could not identify your computer.

• Does PCI bus really occupy 1.8GB

  - by Neil

  I am using a Dell Vostro 1700 laptop which currently has 2GB of RAM. I was considering buying some more memory to upgrade it to 4GB. I am running 32 bit Windows Vista and I know that there can be issues that prevent it from making use of a full 4GB which I believe relate to the fact that memory mapped devices, e.g. graphics card, also need to be allocated addresses in the 4GB range addressable with 32 bits. Consequently I was looking at device manager - resources by connection - memory to see what devices where allocated what memory addresses. I was surprised to see that there was an entry for [80000000 - F3FFFFFF] PCI bus. That is a 1.8GB range of addresses. When I expanded it the only thing in it was [E0000000 - EFFFFFFF] NVIDIA GeForce 8600M GT which is only 256MB. So my question is does the PCI bus really occupy 1.8GB of address space and will it prevent my computer from making use of any more memory than it already has.

• Manually Add the TortoiseSVN Registry information?

  - by Pete Michaud

  I recently installed TortoiseSVN on my Windows 7 64 bit computer. For reasons outside the scope of this question, the installer could not get appropriate permissions to add the keys that TSVN needs in the registry. I'd like to add those keys manually, with a reg file. I tried unzipping the .msi installer to see if the .reg file was there, but no luck. I looked around the net a little, but no luck. I looked in the source code, figuring there must be a file in there somewhere with a list of all the registry changes in one place, but I haven't found any such thing. How can I get a complete list of registry changes for a fresh TortoiseSVN installation?

• Programmatic, script-based, or command line method to change starting program for user on Windows Server 2000/2003?

  - by Joe Majsterski

  I have written an app that we want to distribute to a large number of customers to be used as the shell program when they log onto their server with a particular admin account. I have figured out how to change the starting program by going to Administrative Tools->Computer Management->System Tools->Local Users and Groups->Users, selecting the properties for the user, going to the Environment tab, and changing the program file name under "Starting program" to my new app. But is there a way I could do this with some code that could be sent out and run on all these servers?

• Can Grub be configured to remember the last OS you booted into?

  - by Matthew

  I typically have 2-3 OSes in my boot menu: Ubuntu 10.04 Windows 7 [Sometimes, a third option, such as Ubuntu 10.04 Netbook] If I am in an OS other than the default choice (Windows 7 in this case), and I reboot, Grub boots into Ubuntu 10.04. This shouldn't happen--when I reboot in Windows 7, I want to stay in Windows 7. Is there any way to configure Grub to remember my last choice, and boot into that? Alternatively, it would be even better if Grub only did this when I rebooted (not when I first turn the computer on). I realize this may not be possible, so I'd be happy with simple last-choice-remembering.

• Creating dynamic plots

  - by geoff92

  I'm completely new to web programming but I do have a programming background. I'd like to create a site that allows users to visit, enter some specifications into a form, submit the form, and then receive a graph. I have a few questions about this, only because I'm pretty ignorant: Is there a good framework I should start in? I know a lot of java, I'm okay with python, and I learned Ruby in the past. I figure I might use ruby on rails only because I hear of it so often and I think I've also heard it's easy. If anyone has some other recommendation, please suggest. The user will be entering data into a form. I'm guessing the request they'll be making should be one of a GET request, right? Because I don't intend for any of the data they're entering to modify my server (in fact, I don't intend on having a database). The data the user inputs will be used to perform calculations involving lots of matrices. I've written this functionality in python. If I use ruby on rails, should it be instead written in Ruby? Somewhere I've heard that you can either place the load of the work on your server or on the client's computer. Since the code performs heavy math, which option is preferable? How do I alter the setup to either make the client do the work or my server? Should I be using a "cgi-bin"? In the code that I have now, I use matplotlib, a python library, and then "show" the plot in order to see the graph. I specify the x and y limits, but I am able to "drag" the graph in order to see more data within the plot window. Ultimately, I want a graph to be shown on my site with the drag functionality. Is this possible? What if the client drags the graph so far, more computations must be made? Thanks!

• Where Windows 8 store data of things I recently changed?

  - by user1769787

  Today when I start my computer I see it's not start successfully and show me somthing to Restore like option. I click it and it's rollback many things I have done in my past. suppose. 1.I have uninstalled the software in last days. I have seen them in add or remove option and it's finally work now. (How a software can come back which I have uninstalled). I can see that my email adress which I have removed are come back. My firefox (latest Beta) goes downgrade. I have installed update in last days and now I can see it's goes downgrade. So where they stored all thing which they have rollback.I am sure if they have make a software installed once again which I have already uninstalled then they have stored it somewhere. so Where Win8 store these files which I have restored.

• Mount a remote Linux hard drive as another Windows 7 partition during boot?

  - by zhuanyi

  I would like to mount a hard drive on a remote computer (running on CentOS 6) as a Windows drive so that I can install programs to that drive. The primary hard drive for my Windows machine (which is at home) is pretty small, I have a Linux server sitting in a remote data center with a much larger hard drive and allow me to install more stuff. I know most of you are going to say Samba, unfortunately the biggest problem for me in this case is that I can not mount Samba as a network share unless I start OpenVPN or SSH tunneling first, which is not good for my case because I will install some startup programs to the remote drive as well. Therefore, the remote drive has to be ready and work just like another drive BEFORE any of the startup programs start to load. Is that possible? My home PC has Windows 7 Professional 32 bit installed and the remote server is a Xen virtual server running on CentOS 6. I have admin/root permissions for both. Thanks a lot!

• Can't access server from external IP

  - by Mathias

  I have a problem with my web server; I can't access it from the external IP address. I'm using an IIS 7 server, but I've tried with apache on Linux as well. I have forwarded all traffic on port 80 to my computer, but it just won't work. I've done port forwarding with my Minecraft server, and it did work, but when I try it with a web server, no. I've been looking on many many forums, but their methods don't work for me. My router is a Speedport W 723V, if anyone knows that one. Any help is appreciated.

• SQL Server 2008 database Backup

  - by TaraWalsh

  Hi guys, today I was trying to restore a database with a backup I had made previously on another computer, however I kept getting the following error message: the media loaded on "filepath" is formatted to support 2 media families, but 1 media families are expected according to the device specification I didn't look into it at the time, I just figured it was a bad backup and I'd redo it when I got home. So now I'm trying to do another backup, and I'm getting the above error message for that too. I did backup to a different location at one point, however that no longer exists now. Is there a way i can get passed this error and just do a fresh backup of the database? any pointers would be much appreciated :)
