Level:         Error

Description:

\SystemRoot\SysWow64\Drivers\PzWDM.sys has been blocked from loading due to incompatibility with this system. Please contact your software vendor for a compatible version of the driver.

You should uninstall Prassi Windows Disc Manager

To identify what loads when you boot use Autoruns (freeware from Microsoft).

http://technet.microsoft.com/en-us/sysinternals/bb963902

With Autoruns you can uncheck an item, which disables it from starting, or you can right click an item and then delete it. If you uncheck you can recheck to re-enable the item. It is a much safer approach than editing the Registry and better than using msconfig.

Run Autoruns and select the Everything tab. Click File, Save and, using the scroll to the right, change the “Save as type” option from Autoruns Data (*.arn) to Text (*txt). The file name changes to AutoRuns.txt. Click the Save button and upload the file to your OneDrive as a shared file and post as a link here.

Hello Gerry,

for some reason I totally missed your reply earlier. Thanks for the effort.

I hope you or someone else can make something of these. If not, I guess I'll have to resort to re-install Windows.

Again, thanks for the help.

To troubleshoot most computer problems it helps to look at available clues in the System Information file and the Event Viewer logs. An experienced eye can pick out the needles in the haystack and see more clearly the precise nature of the problem or problems.

Please provide a copy of your System Information file. Type System Information in the Search Box above the start Button and press the ENTER key (alternative is Select Start, All Programs, Accessories, System Tools, System Information). Select File, Export and give the file a name noting where it is located. Do not place the cursor within the body of the report before exporting the file. The system creates a new System Information file each time system information is accessed. You need to allow a minute or two for the file to be fully populated before exporting a copy. Please upload to your OneDrive (formerly Sky Drive), share with everyone and post a link here. Reports in normal mode preferred. Please say if the report has been obtained in safe mode.

Please upload and share with everyone copies of your System and Application logs from your Event Viewer to your OneDrive and post a link here.

To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window expand Windows Logs and select System. Place the cursor on System, select Action from the Menu and Save All Events as (the default evtx file type) and give the file a name. Do the same for the Applications log. Do not provide filtered files. Do not place the cursor in the list of reports before selecting Action from the menu. Do not clear logs whilst you have a continuing problem.
