Win98 Multimedia Problem
Hi All... I started my machine (Win98 fully updated) and experienced:
loss of mouse, display auto changed to 640X480 resolution that could not be changed. Prior to this the PC had been flawless and no known changes had been made prior to the problem. The following was tried: 1. Device Manager: No problems found. 2. Registry Checker: No problems found. 3. Full virus scan (Avast fully updated): Nothing found. 4. Scandisk : Nothing found. 5. Spyware Doctor (fully updated): A few low risk cookies found. 6. SFC: Nothing found. I have resolved the above noted problems but during the process, I discovered the following (which were all fine the last time I used them): 1. First time each session the opening of Control Panel causes Explorer fault in Kernel32.dll. I cannot identify a cpl file which causes this. However, running mmsys.cpl will not do anything even after a new copy is extracted. 2. The Multimedia and Sounds icons are missing in Control Panel. 3. DirectX sound tests fail (Error codes Ox88780078 and 0x80004005). 4. Real and Windows Media Players do not work. Microsoft help for the error codes state they are working on the problem. What I've tried: 1. Ran Sound Blaster's Diagnostic Utility (Dos based): All Passed 2. Uninstalled and reinstalled Windows Multimedia: No improvement. 3. Reinstalled DiectX: No improvement 4. Uninstalled sound card drivers and reinstalled: No improvement. Any and all ideas welcome... |

If this problem is less than five days old, restore a copy of the registry
that predates the onset of the problem and see if that helps. The five-day limit assumes that the computer is booted every day. If it is not booted every day, you may have an old enough registry backup that you can use even though more than five days have elapsed. Note that any registry changes made after the date of the restored registry will be lost. On the Start Menu, select Shut Down and Restart in MSDOS Mode. At the Windows prompt, type: scanreg /restore and hit enter. Once the registry restore screen appears, select the date of the registry that you wish to restore by highlighting it and then click enter. If you see a registry named: Rbbad.cab, that is a copy of the registry that has already been replaced. -- Regards Ron Badour, MS MVP for W98 Tips: http://home.satx.rr.com/badour Knowledge Base Info: http://support.microsoft.com/default.aspx?pr=kbinfo "Ryton" wrote in message oups.com...
