I cant find the driver for my samsung intercept. I would like to connect to my computer but the S3C6410 ANDROID ADB doesn't work

Here is what I have found. You cannot let windows automatically install. You must answer no to automatically install and do it manually. So try downloading this link and unzipping it where you can find it. And then point the install window to this .inf file.
a somewhat official answer is all your problem is lack of androidusb.sys, which located in windows\system32\drivers\, it was deleted or replaced by installing some other android related usb client drivers, however, when you install it manually by pointing it to the android_winusb.inf, it do copy the .sys file into system32\drivers\ again, so when come across with this problem, remove target client device keys (with the VID/PID) in registry in currencontrolset/usb/enum, then better restart windows , and run .exe file to install driver or install it manually, and if you can get the right androidusb.sys from your driver directry (for example c:\progrm files\htc...), you can just copy it into system32\drivers\ but complicated.
I cannot vouch for this file but it looks legit. CaptivateADBDriver

Fix error 651 on windows 7

In windows 7, when you try to connect using your PPPoE connections, you may be faced with the following error: Error 651: The Modem (or other connecting device) has reported an error.
These connections would work just fine with Windows XP or Windows Vista PCs.
Again, you are not alone, this seems to be a known bug in Windows 7 that is being worked at. However, you can workaround this problem.
The RAS PPPoE driver file "raspppoe.sys" found under c:windowssystem32drivers folder seems to be the root cause of the problem. Fortunately, we can workaround the problem simply by renaming the original raspppoe.sys file to something like "raspppoe_orig.sys" copying a working file from a Windows Vista system. If you do not have access to a Windows Vista system. click here to download raspppoe.sys file (unzip). This should help!

Im looking for a Missing sys file on my computer the file pauvcflt.sys is what I need to finish a install update for my usb drivers and I dont know where to look to find it

It is going to be really hard to search for a single, not-so-common system file on the internet. Its probably one tiny file from a heap of a hundred files required for drivers. You haven't given lot of details but as long as drivers are concerned, you can search for them online with the device name etc.

How to replace missing cmicnfg.cpl file

This error occurs after trying to uninstall the updated (and overrated) C-Media WDM Audio Driver for onboard sound that appears after upgrading to XP SP2 and/or going to WindowsUpdate. Likely the driver didn't work, so you tried uninstalling the driver and were going to put back the old Realtek AC'97 driver, but couldn't get rid of the updated driver.

To fix: Start, Run, type in "regedit" (no quotes), and delete the cmaudio string from
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. This makes it so it will not run on startup and try to find the cpl file that was deleted during the uninstall or not installed correctly by the installer in the first place, whichever your case depending on when you started seeing the error. If your sound was working perfectly before this, you are done. To get your sound working again if it isn't, read on -

While still in the registry editor, click on the top computer icon in the Registry Editor to highlight it (so that it will do a complete search of the registry and not just from your present point forward), do a Find (Ctrl+F) and find and delete all KEYS related to cmaudio and C-Media, not just the string entries, but the KEYS, except for that entry in the Run key I mentioned above, just delete the cmaudio string for that one.

Delete the string "CMCPlus" from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Cpls to get rid of the Control Panel icon, and delete the file it points to that resides in C:\Windows\System32.

Download this remove utility from

and run the file you find in the zip file - it can be ran without extracting it from the zip. Take out the C-Media Audio Driver line.

-- NOTE: This utility is for taking the name out of the Add/Remove Programs section only, and does not remove it from your computer, but it is very useful for issues like this when we are MANUALLY uninstalling a program to take it out of the Programs list and should work in 98/ME/2000/XP.

Delete these files from the C:\Windows\System32 directory (or "System" directory for Win98)


Delete everything you can readily delete in C:\Temp, C:\WINDOWS\prefetch (XP only), C:\WINDOWS\Temp, and C:\Documents and Settings\%YourName%\Local Settings\Temp (2000 and XP only), so that there will not be any files left for it to try to recover the driver from. You will likely have to leave things that start with hsperfdata_ and Perflib_Perfdata_***.dat files if you find them, but should be able to delete most others without changing attributes.

Now open the Device Manager (Right-click "My Computer", hit "Manage", then find Device Manager in the Computer Management console). Right-click the C-Media WDM driver under Sound, video, and game controllers, hit Uninstall. Then right-click the top computer icon listed there with your hostname beside it, hit "Scan for hardware changes". It should install a generic "Multimedia Audio Controller" instead of the "C-Media WDM Audio Driver", though you might see that C-Media Audio for just an instant before it reverts back to a generic driver (if it stays, you'll have to go back through the registry again, delete the system files again, and do a full search of your hard drive for those files so they don't get re-copied again). From here you can download your specific Realtek AC'97 Audio Driver setup.exe file here or use your motherboard's installation CD to re-install and you should have sound again.

good luck!!

I can not play audio files

In the windows media player go to > now playing - more options - devices - speakers then changed the audio device to use your soundcard.

Also, uninstall any other players, they usually interfere with each other.
