Hi,
I have a Lenovo T440s with Windows 8.1 Pro installed 8GB Ram and INtel HD Graphics card. Whenever i do video call on skype using desktop version after a while skype freezes for a bit, disconnects the call and shows red on the connection bar. After few mintues it works again, then does the same thing and completely freeze and shutdown. When using skype app(modern windows one) its does similar thing, just does shutdown itself yet freezes, disconnects and reconnect. this is constant thing noticed on both side of skype. however, at the same time if switch to my macbook pro and call the same person, i can do video for hours and no problem !
Is anyone else having the same problem or is it just me. I need a solution please, its really annoying when doingsome serious work !

Hi all,
Hoping someone can help me here. If I use my discrete video card (nvs 42000m) to boot into windows, it will freeze on the sign in page or sometimes on the metro page however when Optimus is enabled it works just fine.
So I thought it was a driver issue. I went to Nvidia and downloaded their latest video card driver for windows 8.1. No help
Uninstalled that, went to Lenovo's support site and installed their recommended driver and all other windows 8 drivers. Again it would freeze
Booted into safe mode uninstalled that, turned optimus back on, and this time used Windows update to install my video drivers (intel and Nvidia both this time).
Didn't work. So I spent maybe another hour or so fiddling and after many restarts i finally found the culprit. It was the Lenovo monitor driver. As soon as I uninstalled that, everything worked fine and I could finally use my laptop with optimus disabled and discrete video card enabled.
Windows update keeps recommending me to update the monitor driver but if I do, then it freezes again so I'm just leaving it as the default generic monitor.
The reason why I made this thread is to inform and save potential users in the future who have a similar laptop to mine (t520 with hd 3000 and nvidia 42000m) with Windows 8 installed and they happen to choose to solely run their laptop with the discrete graphics card, remember to uninstall your monitor driver.
I am open to recommendations and other alternatives.

Hi,
This problem usually occurs when you are installing from an ISO build for a different architecture.
Windows SDK now have different ISO’s for different architectures. Please download the correct ISO based on your system platform and architecture type.

Program in WPF C# using .mdf database with LINQtoSQL freezes for a bit when I load the database

Hello everyone, I have the following code that I run inside a button clicked event in order to compare the username and password
given by the user.
public static bool isAuthenticated(string Username, string Password)
//Open a connection with the databas
using (WHDataDataContext db = new WHDataDataContext())
//Compare the Username and the password and return the result
return db.Users.Any(check => check.Username == Username && check.Password == Cryptographer.Encrypt(Password));
and I use the code like this
private void Button_Click(object sender, RoutedEventArgs e)
//Access the DatabaseControls class and use the isAuthenticated Method
if (DatabaseControls.isAuthenticated(UserBox.Text, PasswordBox.Password))
DialogResult = true; //if the result is true close the dialog
DatabaseControls.setConnected(UserBox.Text, true);
else if (UserBox.Text == "" || PasswordBox.Password == "")
//if the user didn't fill any of the requested boxes show warning
MessageBox.Show(this, "Το όνομα χρήστη και ο κωδικός δεν μπορούν να είναι άδεια", "Προσοχή!", MessageBoxButton.OK, MessageBoxImage.Warning);
if (UserBox.Text == "") UserBox.Focus(); //if the UserBox was empty focus it
else PasswordBox.Focus(); //else focus the PasswordBox
else
//if the result is false show an error and select the UserBox
MessageBox.Show(this, "Δώσατε λάθος στοιχεία, παρακαλώ προσπαθήστε ξανά!", "Σφάλμα", MessageBoxButton.OK, MessageBoxImage.Error);
UserBox.SelectAll();
UserBox.Focus();
My problem is that when I hit the button the program freezes for a moment and the it responds.
I have used this code on a c# application with .sdf file (SQL CE) and I haven't experienced this issue.
I have already tried using threads (Task.StartNew and BackgroundWorker) but I got the same result.
I have also created the DB Context once instead of using (DBContext db = new DBContext()) everytime and I still got the same result.
Could anyone please help?

Async features should have addressed it, you may not just be doing things properly.
Try implementing things this way:
1. If you're not using EF 6 which is the latest version then update your project first. This will allow you to take advantage of EF's async methods.
2. Implement your isAuthenticated method in this manner:
public static Task<bool> isAuthenticatedAsync(string Username, string Password)
//Open a connection with the databas
using (WHDataDataContext db = new WHDataDataContext())
//Compare the Username and the password and return the result
return db.Users.AnyAsync(check => check.Username == Username && check.Password == Cryptographer.Encrypt(Password));
3. Implement your Button_Click event handler in this manner:
private async void Button_Click(object sender, RoutedEventArgs e)
//Access the DatabaseControls class and use the isAuthenticated Method
var authenticated = await DatabaseControls.isAuthenticatedAsync(UserBox.Text, PasswordBox.Password);
if (authenticated)
DialogResult = true; //if the result is true close the dialog
DatabaseControls.setConnected(UserBox.Text, true);
else if (UserBox.Text == "" || PasswordBox.Password == "")
//if the user didn't fill any of the requested boxes show warning
MessageBox.Show(this, "Το όνομα χρήστη και ο κωδικός δεν μπορούν να είναι άδεια", "Προσοχή!", MessageBoxButton.OK, MessageBoxImage.Warning);
if (UserBox.Text == "") UserBox.Focus(); //if the UserBox was empty focus it
else PasswordBox.Focus(); //else focus the PasswordBox
else
//if the result is false show an error and select the UserBox
MessageBox.Show(this, "Δώσατε λάθος στοιχεία, παρακαλώ προσπαθήστε ξανά!", "Σφάλμα", MessageBoxButton.OK, MessageBoxImage.Error);
UserBox.SelectAll();
UserBox.Focus();

The browser freezes for a second while playing Zuma Blitz and Bejeweled Blitz on Facebook. It also freezes for a second while typing. What's going on?

During gameplay on Facebook it falls under Adobe Flash. If I "END" the plugin-container.exe the game crashes and have to refersh the page, in which case the plugin starts all over again. There seems to be no way to play without this process running. My typing is also freezing for a second before it catches up to my fingers. This has been happening for about two weeks. I never had this problem playing these games before.
My OS is Windows Vista and I'm running Firefox version 3.6.13

Update: Firefoxe's best browser was version ~2.2.21!
Ever since then, the user experience has been less and less. Slower browser, feats most users don't use (like skins)... really.. I'm a bit disappointed at the (negative) progress of late.

Windows 7 frequently freezes during games & (end of) videos w/ bootcamp 3.1

Hi,
when running Windows 7 via bootcamp 3.1 on my new iMac (i5, 27", ATI Radeon 4850 HD) it keeps frequently freezing (completely!) when running videos (e.g., at the end of 5-10 youtube videos) and especially when running 3d games (e.g., while switching to an in-game menu after 10-20min gaming). Even though, the Windows event logging unfortunately has no entries before the freeze, I'm certain its an ATI driver issue. Hence, I tried all drivers available or suggested in discussions, but without any success. Concretely, I tried:
- ATI 8.661.0.0 (driver date 23-09-2009, bootcamp 3.0) => freezing
- ATI 8.681.0.0 (driver date 24-11-2009, bootcamp 3.1) => freezing & color banding
- ATI 8.732.0.0 (driver date 04-05-2010, www.ati.com, mobility driver) => freezing
Does anybody has a working solution, a workaround, or another idea what else I could try?
Thanks in advance,
Mario

Don't know about the earlier poster, but that is exactly what I did. I don't know if you can download the ATI drivers from ATI without also installing Catalyst. I definitely got it as part of my download, and even tried fiddling around with the settings in there, but my systems still freezes randomly

Whay am I having script errors with some of my websites only on Firefox, not other browsers, causing the computer to freeze for a bit at a time.

I keep getting "script" errors and my computer locking up while using Mozilla Firefox on some of my websites. I don't have this problem while using Internet Explorer. Why has this just started and how can I resolve this? I like Firefox, but will have to start using a different browser if this doesn't get resolved.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Windows Professional x64 Support for Audigy 2 ZS Video Edi

Is there some reason why the Video Editor isn't x64 compatible yet?

For Video Blaster Editor ... we are currently taking steps to insure it runs under 32-bit Vista.
Regarding Vista and Audigy 2 ZS Video Editor ... here are some tips from another user. [I am going to answer every query on this thread with these instructions ... so you'll be sure to see them quite a bit]:
I have used the follwoing procedure to install a working configuration of the Audigy 2 ZS Video Editor in a clean install of Vista Ultimate.
() Download from Creative Labs (US) site: http://us.creative.com/support/downloads/ the following files:
(a) Creative Sound Blaster USB Series Windows Vista Driver .00.0060 - USBVS_PCDRV_LB__00_0060.exe (from the Vista section)
(b) VidCap for Creative Sound Blaster Audigy 2 ZS Video Editor .00.000 - A2VX_PCVDE_L9__00_000.exe (from the WinXP section)
(2) Use WinZip or WinRAR to open the file (b) and extract the folders \DrvInst and \Vidcap into your Vista Downloads folder.
(3) Connect the Video Editor to the power supply and a video source; connect the USB cable to your PC. Ignore the "Found NEw Hardware" dialog that pops up.
(4) Doubleclick on file (a) to install the Creative Sound Blaster USB Series Windows Vista Driver, and follow prompts as required; accept all defaults. After install is complete, let the PC reboot.
(5) After rebooting, in the "Found New Hardware" dialog that appears, select the options to search for a driver, don't go online to search, browse for a driver and point the search at the \DrvInst folder you extracted in (2) above. The USB video driver will be installed from the \DrvInst\Video\Driver\Win2k.
(6) After the video driver is installed, doubleclick on the Setup.exe file in the \Vidcap folder you extracted in (2) above to install the Vidcap application.
(7) Setup the options in Vidcap, and run a test recording.
Happy capturing under Vista.

Browser freezes for a second while playing Zuma Blitz and Bejeweled Blitz on Facebook

Zuma Blitz hangs while playing on Facebook

The only way to turn off the ipod is to use the sleep/wake button and then turning the red slider. The only setting to switch it off automatically would be the Timer function:
Timer
Set the timer: Tap Timer, then flick to set the number of hours and minutes. Tap Start to start the timer.
Choose the sound: Tap When Timer Ends.
Set a sleep timer: Set the timer, then tap When Timer Ends and choose Sleep iPod.
When you set a sleep timer, iPod touch stops playing music or video when the timer ends.
If you start the timer and go to another iPod touch application, the timer continues
running in the background. (user guide page 89)
And if the batteries are almost empty the ipod will turn off by itself and you will have difficulties to start it up again until you charged it a couple of minutes.

All advice would be appreciated.

We ended up getting iTunes cleanly uninstalled and were able to re-install without issue. All is now mostly well.

I can confirm disabling APSDaemon.exe, aka, new Apple Push for WiFi Sync and renaming (or deleting if you are more risk oriented) APSDaemon.exe and APSDaemon_main.dll in this folder "C:\Program Files (x86)\Common Files\Apple\Apple Application Support" resolved my issue.
Alternatively, another slightly more annoying but less techy workaround for those nervous about changing filenames is to start iTunes in Safe Mode every time. You must do it via Programs > iTunes > hold down Ctrl-Shift then click iTunes (does not work if you do it by clicking a short cut in programs list or taskbar, whatever...). Maybe this disables WiFi Sync by default, dunno. Don't care at this point, but it seemed to work.
I can live without WiFi Sync for now, but its a nice feature I would really like to use in the future.
Apple please fix!!!

Firefox often Freeze for no Reason, i'm running on windows 7 ultimate 32-bit, with intel i3-380M 2.5Ghz, 2 GB DDR3 Memory

When i'm opening firefox, it always freeze for about 1 minute, i'm not sure how it's happening, but i also run Winamp when opening firefox, when the firefox frozen, my entire desktop will also freeze, it sucks , i need to wait for 1 minutes

I have a problem with the synchronisation of my iPhone and iPad with Outlook 2007 on my 64-bit Windows 7 PC. For several years, I have had no problems with the synchronisation by cord connection and iTunes between these programmes. However, a few months

I have a problem with the synchronisation of my iPhone and iPad with Outlook 2007 on my 64-bit Windows 7 PC. For several years,
I have had no problems with the synchronisation by cord connection and iTunes between these programmes. However, a few months ago I decided to use Mobile Me. However, there were problems with duplication of calendars and then “rogue events” – which could not be deleted – even if deleted on Outlook and on the iPhone (or both at the same time) – they would just reappear after the next synchronisation. All other synchronisation areas (eg Contacts, Notes etc) work fine.
I have looked for help through the Apple Support Community and tried many things. I have repaired my Outlook. I have repaired my .pst file in Windows. I have re-installed the latest version of iTunes on my PC. I have re-installed the firmware on my iPhone. I have tried many permutations on my iPhone. I have closed down all Mobile Me functions on the iPhone. I have spent upwards of 24 hours trying to solve this problem.
What am I left with? Outlook works seamlessly on my PC. My iPhone calendar now has no events from my calendar, but does not synchronise through iTunes. Nor does it send events initiated on the iPhone to the Outlook. I am at the point of abandoning iPhones and iPads altogether. I need to have a properly synchronising calendar on my phone. Do you have any suggestions?

In the control panel goto the "Lenovo - Power Manager" and click the battery tab, there is a maintenance button in there that will let you change the charging profile for your battery. (from memory, so exact wording may be off)
The lower the numbers you use there, the longer the battery *should* last. These batteries degrade faster at higher charge levels, however storing them at too low of levels is also not good for them... I've read that 40% is optimal, but just not realistic if you use your computer.

Firefox freezes for a while when the Downloads window pops up

Whenever I start a file download (regardless of its size), Firefox freezes for a few seconds, sometimes longer. I deleted the downloads.sqlite file and it helped for a few days but it started happening again. I deleted downloads.sqlite again but this time it wouldn't help at all. I even installed DownThemAll add-on as some people suggested but it happens with it too.
I've been using Firefox for 7-8 years now and never had any issues that could not be resolved but this plus some other freezes or crashes from time to time is starting to be annoying. I have all major browsers installed because of my work but kept FF as default one but I'm starting to consider a switch after all these years.
Can anyone suggest a soluton? And I don't consider disabling the Downloads pop-up window a solution.

Thanks for your input but I already said that I deleted downloads.sqlite.

I am using Lightroom 5.7, 64 bit with Windows 7 Professional. For no apparent reason, I now get an error message when I export a photo, say a raw image to a JPG. However, the exported image seems to be OK. But now I notice that my LR directory of folders in Library view does not show images correctly: If there is a folder with sub-folder(s), the folder will indicate 0 images, but the sub-folders show the proper number of images. What happened and is there a fix? I tried uninstalling Lightroom and re-installing, but problem persists.

HP PSC 1315xi All in One from 32-bit XP to FULL FEATURE for 64-bit Windows 7

Switched from 32-bit XP to 64-bit Windows 7, which did not install all printing features or my scanner. Know a lot of people have this problem, can't find the forum which is exactly for this particular problem, and can't find an HP download. There are so many other companies on the HP Support pages. Might you include on your title page how to re-read this subject?
I'm afraid I'll lose my print and copy functions forever if I first Uninstall. Would checking "Add Printer" preserve my present version until after I get a successful download or maybe even a new Disk for 64-bit Windows 7? I haven't even found that yet. Thanks. [edited by Moderator]

Good day AmerEagle,
I understand you have upgraded from Windows XP to Windows 7 64bit and are looking to install the driver and software for your PSC 1315xi. I will certainly help you!
Here is the direct link to the download for the Windows 7 full driver for your printer:
