Many problems with my PC since I dusted it off!


I have been having many problems with my pc. I was dusting when I hit a cord and the computer went into safe mode. Under system properties it says I have three problems. They are: Compatibility-mode paging reduced overall sytem performance, Drive A is using ms-dos compatability mode file sytem, and Drive C is using ms-dos compatability mode file sytem. This is making it impossible for me to use my PC for any useful aplication like internet or progams. Another problem I have faced from before this is defragenting my pc. I never see the percent bar go past 1. If you can help me with any of my problems I would be most happy.

For the first problem about compatibility-mode paging reduced overall system performance

Try disabeling goback To disable GoBack prior to setting up Windows:

1 Click Start, click Programs, and then click GoBack.

2 When GoBack menu appears, click Options.

3 On the History tab, click Disable GoBack

4 In the GoBack Setup dialog box, click OK to restart your computer.

6 Before Windows desktop appears, the GoBack Disable dialog box appears; click Yes to proceed

7 In the dialog box saying that GoBack has been successfully disabled, click OK.

8 When prompted to re-enable GoBack the next time you restart, click No.

For the second problem Drive A is using ms-dos compatibility mode file system.

If it's only the A: drive it's really not a big deal But open device manager, click the plus by flop

For Drive C is using ms-dos compatibility mode file system.

Open up a DOS window and type : type config.sys

To force Windows to attempt to reinitialize the protected-mode IDE driver you'll have to remove the noide entry from the registry:

1 Start the Registry Editor

2 Go to HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ IOS

3 Delete the NoIDE entry

4 Search your registry for BAD_IDE (You can Search the registry by pressing F3 while working in the registry editor.

5 Delete any BAD_IDE values you find

After you update the registry, restart Windows Windows will then attempt to initialize the protected-mode driver for the controller If no problems are encountered, the file system and virtual memory will operate in 32-bit mode, and Device Manager will not display an exclamation point in a yellow circle for the IDE channels.

If the protected-mode driver is not initialized properly, an error message will be displayed and the NoIDE registry entrypy disk controllers and remove the floppy disk controller Restart the machine
