Sounds like you've got a memory issue, sometimes when the computer is working with complex memory calculations the module dumps the data on the stack and poof reboot. Try a newer memory module? Also go into bios and see what options you have for memory processing, depending on age of laptop you might be able to disable the ALU in the CPU but it sounds like a memory issue.

ALso try reinstalling direct X, and even possibly windows itself.

Modem driver, consult mfg.

DVD/CD drive won't recognize discs. System says corect driver installed


Is it a disc that someone made on their computer and gave to you or is it one you purchased from the store? Computers sometimes have a hard time reading a disc that someone made and gave to you. Try a disc that you purchased and see if it plays it.

See if you can update the driver in the device manager.

Uninstall the DvD Drive from the device manager, then reboot and let it reconfigure everything. Go the Control Panel and under System find the device manager. Right Click on the dvd drive and select uninstall. Reboot.

Reseat the the disc by unplugging the power cord, remove the battery, then turn the laptop over and remove the screw that holds the dvd drive in place. Pull the drive out, then put it back it.

If you are using Windows Media Player try the VLC player.
Try using VLC as your player. Go to www.google.com andin the search box type "download vlc" (without the quotes). Look for the Video Lan download from site www.videolan.org/vlc Downloadand install it. It downloads and installs in 3 minutes or so. It'sa very fast player, smooth and it can play just about any type of dvd formatsand media. It's totally FREE.

When I try to burn it says DVD is copy protected. And when I download Booyah plug-in it still doesn't work.


Not very sure what happened with your DVD burner program. For anyone who wants to create a DVD disc from videos, he or she can give this DVD Creator software a try on the Windows PC or Mac.

If you wanna remove DVD disc protection and then back up DVD movies freely, try this DVD copy program as well.

Error: 651


What causes the Error 651?


  • The raspppoe.sys file has become corrupted. RASPPPOE.sys is an acronym for Remote Access Service Point-to-Point Protocol over Ethernet. This is a windows driver that many broadband service providers use for authentication when connecting to the internet through a broadband modem.
  • Possible problems with the Local Area Network (LAN) card driver.
  • There may be a conflict with the modem driver and your operating system.

How can I resolve the problem?


  1. Try rebooting your computer. Sometimes a simple reboot will clear your cache and reset the modem.
  2. Rename the existing RASPPPOE.sys file and take a copy of the file from a Windows Vista system. Apparently this problem has been reported for Windows 7 users, by renaming the current file and copying this file from Windows Vista, it should resolve the issue. This file can be found in c:\windows\system32\drivers. You can download a copy of the driver for Windows Vista here (http://www.windowsreference.com/wp-c...5/raspppoe.zip)
  3. Re-install LAN Driver. It's also possible that your drivers are outdated and you may need to download updates from the manufacturer's website.
  4. Install the latest patches for your current Windows OS.

Shaky sound and video


To solve this:

1- Check if you have more than 1 DVD player program installed. If yes, uninstall any you don't use (being careful not to uninstall the one you use or that's needed for the recording part of what you do)
2- Check if you have more than 1 Media player software like VLC media player, Microsoft Media player (automatically installed) etc.

Because it also affects video played saved on your computer (assuming AVI or video you play using Windows Media Player or another player) and DVD playback, its usually a program that is conflicting with another of the same type (plays media Audio/Video). If the above solution did not work, try performing the "system restore" and choose a date of when you definitely remember it working without chatter. If this is not an option, proceed below.

If your computer has been performing regular updates and you happen to be using a new Windows Media player, do you remember if it happened during a computer software update? If yes, the fault lies with Windows Media player having performed an upgrade to itself. You may want to "demote" media player by going to Control Panel and "add or remove programs" list (making sure "show updates" is checked) and scroll down until you see Windows Media player. Then uninstall the latest update it has performed.

If you installed another media player/DVD player program(s) and it coincides with your problems, uninstall it. Multiple DVD/Media players have their own settings, file changes/updates and they can affect one another if installed simultaneously on 1 system.

Let us know how it goes and rate us. :)

My acer extensa 2300 dvd-rw drive wont work?


Try this; Goto > DEFAULT PROGRAMS > SET YOUR DEFAULT PROGRAMS > and check the settings for each media application you have on your system.
If you just use Windows Media Player then do this aswell > open windows media player, > TOOLS > OPTIONS and go through the various tabs and check the BURN & RIP options
If They dont work check that the device is installed correctly and is enabled! You can do both of these by going to CONTROL PANEL > DEVICE MANAGER.
Scroll down the list till you find DVD/CD-ROM DRIVES.
Right click on the Driver and click properties,you will then be able to varify the two.

Cannot play dvds as drivers lost when changing from vista to xp home.when enter dvd it says dvd decoder and drives lost


If you are running XP, you will need to install a DVD playback application. IN VIsta, DVD playback is native to WIndows, in XP, Dell used a program called Cyberlink PowerDVD. You can either buy PowerDVD on line or download a free DVD playback application from places like Download.com. I've had good luck with the AVS DVD player here:

http://www.download.com/AVS-DVD-Player/3000-7970_4-10491860.html?cdlPid=10669161

If you just installed XP on this system, it is also important that all the drivers are installed and in the correct order. Dell's preferred order is:

Notebook System Software
Chipset Utility
Video Driver
Sound Driver
Modem Driver
Network Driver
Wireless Driver
Touchpad Driver
Quickset Utility

Drivers are available here:
