You have one of two reason for this problem. The AC97 is your sound device in your PC. When windows went to use the AC97 either the device it self is defective or the software somehow became corrupt.
Lets check the driver in your PC. Left click the start button, slide up to & open control panel, open System icon. System Properties window will open. Click the hardware tab, than click the device manager button. Scroll down to the + sign next to Sound, video and game conreoller. Do you see a yellow ! point any where? If your answer is yes than your sound device AC97 needs the driver software re-installed. You did not post the model number of your PC or the manufacture's name for your PC.
Ex: Acer, Dell, Hp ect.
Model numbers ex: Aspire E500, Inspiron 530, Pavilion a6450z ect.
With that information I can go to their web site & find your correct (possible updated) software for your AC97 sound driver.
I can guid you to the web site & have you download the driver software & save it on your PC. (untill than).
Your PC came with a manual & Cd's. You can load each cd & search for the sound driver for your AC97 sound card. Once found you can install the sound cards software for your version of windows.
If you post the requested information I will find your needed software.

If you have more questions feel free to ask.

Have a great weekend!
Mike

Blue screen of death. unable to download drivers. can not get to safe mode. cannot reload orperating system disks.


First off, note down all relevant information when you see a BSOD flash across the screen. This includes the error number and friendly name from the 'bugcheck' section of the stop error (see above), and any file names specified in the 'driver information' section.
If the BSOD comes up on the screen for a split-second before the PC restarts and wipes all the useful information away, we need to change some settings within WinXP. In most cases, it should be possible to stop your PC from automatically restarting when it develops a major error, allowing you enough time to jot down the BSOD error message. If you are using WindowsXP, right click on my computer > Properties > Select the 'Advanced' tab > and under 'startup and recovery' click the 'settings' button. This will open a new window, and under the 'System Failure' heading, uncheck 'Automatically restart.' Continuing on, attempt to restart the computer normally into Windows. If the BSOD occurred while booting Windows, you may be taken to a troubleshooting menu and will have to select 'attempt to start Windows normally.' If your computer starts correctly, continue using it and store the error information for later reference. If the BSOD reoccurs at random or irregular periods, see Section D below on troubleshooting intermittent stop errors.
If your system does not start correctly or the stop message happens again, reboot the system. When the POST (memory checking) screen comes up, press F8 repeatedly. This will bring you to the Windows advanced options menu.
In the Windows advanced options menu choose 'safe mode' to attempt to boot into Windows Safe mode. Safe mode loads Windows XP with a minimal set of drivers and no automatically loaded software. If faulty software or drivers are causing your BSOD problem, safe mode should load correctly. If safe mode loads correctly, refer to Section A below on 'troubleshooting software stop messages.'
If safe mode does not load correctly, and/or you get the same stop message upon attempting safe mode, it's time to try the 'restore last known good configuration' option in the advanced options menu.
Restart your computer, pressing 'F8' again to load the advanced options menu and select 'last known good configuration (your most recent settings that worked).' This uses Windows XP's built in system restore utility to restore the most recent save point, which should be the last time you installed any drivers or other software. If your system boots normally after this operation, hopefully your problem has been fixed.
If you are still receiving a Blue Screen Of Death after the above procedures, or if system restore was disabled on your system, note down any new information on the error and start thinking. Did you install any new hardware or software just before this problem occurred? The driver information section of the BSOD may help with this.
If you did install new hardware or software, and you think you know what it might be that is causing the problem, this gives you a big boost in resolving the situation.
Otherwise, proceed to the advanced troubleshooting sections below. Chances are your error is hardware or system file based and will require more effort to repair.
Specific Repair Instructions
If you have a reoccurring Blue Screen Of Death or crashing problem, and can't use Windows effectively because of it, it's time to look at more specific methods of troubleshooting your problem. Depending on the results of the basic troubleshooting steps above, you should have a good idea of whether the problem that is causing the stop messages is related to software or drivers you have installed, or is a hardware or system file issue.
Essentially, if you can't boot into Windows XP safe mode because of crashes or Blue Screens Of Death, you likely either have a hardware error or one or more essential system files is corrupted or missing. If you can boot into Windows XP safe mode, but get constant or frequent BSOD's when running XP normally, you have a software or device driver problem.

Make sure that if you added any RAM to your computer which is a common cause for BSOD that you added the correct RAM for your computer and that it is equally distributed in the ports meaning each port for the RAM has the equal amount of RAM on each side (eg, one stick 1GB, and the other has 1GB, etc).

Dll driving me nuts


Hello EricS777

The part where it looks like your xp stuff and vista stuff switch drives is normal. Only the Operating System associates the hard drives by letters this does not mean your hard drive files are switching. This happens because D: drive is Root of Vista OS and Root of any OS in windows gets the C: drive lettering.

dwwin.exe, drwtsn.exe dll is the "Microsoft Application Error Reporting" tool.

I think the message means that something is crashing during system shutdown. When the crash occurs the OS launches dwwin.exe to report the error, however the windows operating system is shutting down and so the application can't launch make the system lockup or hang.

Your problem isn't with dwwin.exe, you need to find out what is actually crashing at shutdown.

If you can`t find out what it is, try going to Administrative Tools/Services and disable the “Error Reporting Service”. You don`t want that running anyway.

Also right click My Computer/Properties/Advanced/Error Reporting
Put a check at both
Disable Error Reporting
But notify me when critical errors occur

Then, if that was the cause and the message stops, we`ll have to try to identify the cause.

Sounds like a spyware problem. I would suggest booting in safe mode with network by pressing F8 just after you turn on your computer then doing a virus scan using this website. Its free.
